Food Waste and Food Processing Waste for Renewable Energy Production


Purpose *          

This high efficient and low-cost eggshell catalyst could make the process of biodiesel production economic and fully ecologically friendly. The ecologically friendly and economic process could effectively reduce the processing cost of biodiesel, making it competitive with petroleum diesel.

What did we do? 

The acid value of Jatropha oil was more than 2 mg of KOH g-1. The methanol, sodium hydroxide (NaOH), and sodium methoxide (CH3-ONa) were high-performance liquid chromatography (HPLC) grade. The experimental setup is shown in Fig. 1.

Fig. 1. Experimental setup

A microwave synthesis reactor (NN-S235, Panasonic Co., Ltd., Taiwan), equipped with a mechanical stirrer and a condenser (LC-10, Hi-point Co., Ltd, Taiwan) was used for microwave reactions. The stirrer was operated at 600 rpm with a magnetic nucleus. Various catalysts (CH3ONa and NaOH), reaction times (1–6 min), methanol to oil molar ratios (3–15), and reaction powers (200–750 W) were tested. The analytic method of methyl ester content in this study followed Taiwan CNS15051 (Chinese National Standards). A GC (gas chromatography; GC-6890, Agilent, USA) system equipped with a FID (flame ionization detector) was used to determine methyl ester content.

What have we learned? 

Experiments were carried out using different catalysts in order to investigate their influence on the methyl ester yield. The microwave system was operated with a reaction time of 165 min, microwave power of 750 W, and methanol to oil molar ratio of 9. eggshell and oystershell were used as the catalysts. The fractions of the catalysts were 3, 4, 5, 6, and 7 wt%.

Fig. 2. Effects of the amount of eggshell catalyst on the yield of Jatropha methyl ester with the microwave system

As shown in Fig. 2, the yields of methyl ester were 85.5%, 89.1%, 91.7%, 87.4%, and 86.8% for 3, 4, 5, 6, and 7 wt% eggshell catalysts, respectively. The best performances were with 5 wt% eggshell catalysts. Comparing the eggshell as catalyst, operational condition addition of 6 wt% oystershell catalysts as shown in Fig. 3, the reaction time was 180 min, reaction temperature was 65 ℃, and the methanol-to-oil ratio was 9:1.

Fig. 3. Effects of the amount of oystershell catalyst on the yield of Jatropha methyl ester with the microwave system.

The results indicated that the catalysts derived from eggshells showed yield better than oystershell for biodiesel production.These results indicate that although excess catalyst might increase the biodiesel yield, the amount of glycerin also increased due to saponification, causing a reduction in biodiesel yields.

Future Plans 

High active, reusable solid catalyst was obtained by just calcining eggshell and oytershell. Calcined eggshell and oytershell exhibited high activity towards the transesterification of jatropha oil with methanol to produce biodiesel. The method of reusing eggshell waste and oystershell to prepare catalyst could recycle the waste, minimizing contaminants, reducing the cost of catalyst, and making the catalyst environmentally friendly. This high efficient and low-cost eggshell catalyst could make the process of biodiesel production economic and fully ecologically friendly. Future, the ecologically friendly and economic process could effectively reduce the processing cost of biodiesel, making it competitive with petroleum diesel.

An NE-1441 Project: Proposed Methodologies for Administering a Multi-State Environmental Best Management Practices Survey of Equine Properties


*Purpose 

Several states have reported that equine are the fastest growing segment of the livestock industry. Nationwide, equine has increased by 77% since 1997; and it is reported there are approximately 9.5 million horses in the United States (AHC, 2005). Proper management of equine operations requires the adoption of Best Management Practices (BMPs) to balance nutrient production and prevent erosion. Government agencies are concerned about non-point sources of water pollution and have focused on agriculture, including equine operations, as a major contributor to water quality issues. Many states’ laws have regulated equine farms, requiring farm managers to incorporate BMPs. The objectives of this proposed national (multi-state) survey are to quantify and assess the use of the equine industry’s BMPs in pasture management, erosion control and to examine potential environmental impacts. Few state studies have investigated horse BMPs in the U.S, and more research is needed to assess the effect of horse farm management on U.S. water quality. Knowledge of the current scope and nature of equine industry management practices are important when developing regulations, laws, and educational programs to enhance the stewardship and govern land management on equine operations.

What did we do? 

The methodology to assess horse property manager/owner practices consists of gathering a minimum of 150-2,000 names and email addresses of horse owners/farm managers from the 15 states involved in the NE-1441 project. Some of the N. E. states have fewer equine operations. An email containing survey information and a link to the 40 question online survey will be sent to horse farm managers in 2016. Three follow-up reminders will be sent to non-responding addresses. It is hoped to have a 40% response rate. Data will analyzed using SPSS 16.0 (SPSS Inc., Chicago, IL) for descriptive statistics, determining response frequencies and percentages.

The Questionnaire Instrument will include the following areas:

Part I General: Involved in the horse industry? Are you the owner or manager of a horse operation? If No, then you are finished taking the survey. Business or Hobby?

Part II Demographics: Location, State, County, Survey participants gender, age, Size of farm total acreage, Confinement areas, Pasture areas, primary and 2nd use of operation, Highest average number of horses on property? On average, how many hours per day do your horses spend grazing pastures by seasons?

Part III Horse Pasture Management Rotational Grazing, unlimited access,Pasture Management Plan, Agricultural Erosion and Sedimentation Plan weed control and type, mowing, resting pastures,Sacrifice lots, pasture topography, surface water, Sheds and barns,divert runoff, roof gutters.

Part IV: Horse Pasture Applications and/or Evaluation: Line, Fertilizer, Herbicide use, Seeding practices, Lime, Soil testing.

Part V: Horse Manure Management: Nutrient Management Plan, primary manure management, collection, storage, uses, removal.

Part VI: Conclusion: What are your limitations in altering the management of your horse operation? What information resources do you use for your equine farm operations?

What have we learned? 

The questions for an equine related APHIS/USDA animal agriculture survey need to be more specific to the activities and needs of the horse industry. Whereas most animal agriculture operations do not deal directly with the general public as a necessary component of their business plan, the horse industry depends on active and engaged clientele. If we are able to gather national data through a single effort survey, the resulting information could be compared and sorted in a consistent and statistically reliable manner, allowing educational materials and opportunities to be tailored to area or regional needs.

Future Plans 

A survey will be conducted by the NE-1441 (a northeast regional Hatch research group focusing on environmental impacts of equine operations) participating states to determine the use of the following best management practices: managed storage area, composted manure storage, stream crossings, buffers and vegetative filter strips, heavy use pads and sacrifice areas, soil testing, and fertility management on fields receiving manure. Develop means of determining the impact of equine outreach programs, more specifically determination of BMP adoption rate.This will allow us to chart progress among producers who use extension services and/or implement BMPs with the assistance of extension or other service providers such as NRCS, state departments of agriculture, and etc. We will work with social scientists to determine adoption rates, what the reasons for resistance to adoption are, and how to develop programs to overcome this resistance.

Analysis of total Carbon, Nitrogen, and Phosphorus Contents in Soil Cores Over 10+ Years from Horicon Marsh in Dodge County, Wisconsin


Why Look at Marsh Soil Nutrients?

The purpose of this project was to evaluate changes in carbon (C), nitrogen (N), and phosphorus (P) in samples from identical locations taken ten years apart from Horicon Marsh in Dodge County, Wisconsin.

The area surrounding the marsh is primarily agricultural and has the potential to contribute nutrients to the marsh, affecting the fertility of the soils and changing the ecosystem.

What did we do?  

We hypothesized that carbon, nitrogen, and phosphorus would show significant increases over the ten-year interval between samplings.

Sample sites were positioned every ¼ mile along east-west transects throughout the marsh. A soil core was obtained at each sample site in the winter of either 2002 or 2003. The same sites were revisited and new samples collected in winter of either 2012 or 2013, ten years after the initial visits. The top five centimeters of each soil core were oven dried at 105°C for 72 hours.

Total carbon and nitrogen were analyzed by combustion using a PerkinElmer 2400 series II CHNS/O Analyzer. Total phosphorus was analyzed by the Olsen P-extraction method on a QuikChem FIA+ 8000 series Lachat analyzer.

A paired t-test (α=0.05) was used to compare nitrogen and phosphorus values. Carbon data were compared with a Mann-Whitney ranked sum test at the 95% confidence interval.

What have we learned?  

Carbon and nitrogen did not increase significantly over the time period. Carbon is generally bound in soil organic matter; in histic wetland soils, changes attributable to land use might be difficult to detect due to the already high organic matter content. Nitrogen accumulation was likely mitigated by denitrification processes.

Phosphorus concentrations were greater in the second set of samples. Phosphorus adsorbs tightly to sediment and organic material, which would prevent its removal by flowing water. Changes in land use, especially row crop agriculture in the Horicon marsh area, could contribute runoff inputs of soil particles carrying phosphorus with them. This may explain significantly increased phosphorus levels between the start and end of the study period.

Future Plans  

Future studies might quantify land use changes, their extent, and their impacts on the marsh ecosystem; analyze spatial patterns of phosphorus accretion to determine if it is cycling equally throughout the marsh; and determine the impact of denitrifying bacteria and anaerobic conditions on nitrogen accumulation. Additional research could include testing the water column of the marsh for dissolved nutrients; and sampling the Rock River at its inlet to and outlet from the Horicon Marsh to determine nutrient flux to the stream from the marsh.

Evaporation Ponds – Waste Storage Facility Design Spreadsheet

Purpose

An assessment tool was developed to simplify the process of determining minimum waste storage pond (WSP) dimensions in conjunction with assuring adequate evaporation of stored runoff over time. In contrast to typical WSP designs that require intermittent pumping and handling of waste water, evaporation ponds (EPs), as waste storage facilities used to contain storm runoff from feedlots, offer long-term passive management and may be acceptable alternatives where annual evaporation exceeds rainfall and where landowners deem typical WSP designs as impractical.

What did we do?

EPs are passive management structures that allow landowners to avoid having to periodically evacuate accumulated water from typical WSPs via pumping or other means (active management). Both EP and WSP systems are designed to collect and store contaminated runoff and sediment from feedlots, but it is assumed that the use or disposal of the contaminated water is practical in the case of WSPs. It is not always practical. Some ranchers operating in arid areas who manage small feedlots during the winter have expressed interest in EPs over WSPs stating that the passive management method will keep their costs low while fitting better with their current operating systems.

At the onset of our first EP project, we found no NRCS tool specific to the design of EPs. The principles outlined in our Agricultural Waste Management Handbook (United States Department of Agriculture, NRCS, 1999) regarding waste storage facility design and our guidance for runoff produced during a 25-year, 24-hour precipitation event using the NRCS Curve Number Method (United States Department of Agriculture, NRCS, 2004) still apply. Next, we chose to build a spreadsheet that allows the designer to perform the multitude of computations needed to consider distinct EP geometric configurations, time periods, and hydrology in the design of EPs. In a nutshell, the model consists of estimating amounts of water and sediment that the EP retains while accounting for water losses due to evaporation and any periodic removal of sediment (Figure 1) over time. For any given EP geometry, the design is considered viable so long as the water level does not supersede the elevation of the embankment top minus freeboard.

The mathematical functions applied are deterministic and follow Natural Resource Conservation Service (NRCS) guidelines (United States Department of Agriculture, NRCS, 1999). Mean monthly evaporation and precipitation data are available via the National Oceanic and Atmospheric Administration website, and runoff from the 25-year, 24-hour precipitation event is estimated using the NRCS Curve Number Method (United States Department of Agriculture, NRCS, 2004).

What have we learned?

1) The design of evaporation ponds, to be used as waste storage facilities, is complex, entails many variables, and typically requires multi-year tests.

2) Simulation of waste storage pond storage levels over time provides visual results that allow the designer to observe expected behavior of these systems and judge whether or not evaporation ponds are viable alternative systems to typical waste storage facilities in which frequent evacuation of storage materials is required.

3) Calculations using a spreadsheet are simplified to the extent that dozens of scenarios can be assembled and executed within a reasonable timeframe. This allows designers to study the results from such sensitivity analyses where one or more variables must be examined at numerous levels/values due to uncertain data at particular sites.

Future Plans

1) Train NRCS field staff regarding the potential pros and cons pertinent to these systems in comparison to others.

2) Encourage landowners to consider evaporation ponds as viable alternatives in areas with low precipitation/runoff.

3) Monitor site input variable values and the evaporation pond sediment and water levels over time to assess whether or not the models applied forecast overall evaporation pond behavior.

The Importance of Nitrogen Stabilization

This session will highlight the importance of nitrification inhibitors and how they help delay the conversion of the ammonium form of nitrogen into the nitrate form which then can lead to leaching and denitrification. By using a nitorgen stabilizer, the plant has access to the ammonium form of nitrogen for a longer period of time in the root zone, where it needs it the most.

What Did We Do?

The active ingredient in Instinct II and N-Serve, nitrapyrin, is formulated to put the bacteria known as nitrosomonas, which convert the ammonia form of nitorgen to nitrate nitrogen in the soil, in a static state so that the ammonia form can be uptaken by the plant in the most stable form of nitrogen. Our product treats the soil, not the nitrogen, but uses nitrogen as the carrier, to prevent leaching and denitrification that can occur from warm, wet soils in the spring season. Our product has been tested and approved by the EPA for 40 years and has have numerous (189+) 3rd party and university data that supports that it does what we say it does, inhibits nitrification. In addition, there are other advantages to protecting your nitrogen investment which can lead to higher yields, faster dry down, higher test weight in corn and wheat and in addition, has no negative effect on protein on wheat. Instinct II can be used in UAN, Urea, or Liquid Manure. N-Serve is used on anhydrous ammonia.

What Have We Learned?

Based on the 189+ different 3rd party and university trials, plus the meta-anaylsis published in 2004, we have proven to increase crop yield by 7%, increase soil retention by 28%, decrease nitrogen leaching by 16%, and decease greenhouse gas emission by 51%. Our retention is extremely high on his product, and has proven to be a significant benefactor when used in manure (this year along, our averages on yield increase have been 12+ bushels). Future plans further expansion to outside of US markets, Canada, China, UK, and Australia alongside other EU countries. Further market expansion in the United States into other crops such as specialty crops markets, improvement on formulation for newer, expanding markets.

Northwest Winter Feeding Assessment Tool


Can Grazing Operations Be an AFO Based on Winter Feeding Practices?

Assessment of and protection for water quality resource concerns impacted by livestock winter feeding practices

Grazing lands management assistance with NRCS focuses on forage and range conditions for livestock producers and management practices during the growing season. Animal waste management system installations with NRCS have focused on water quality protection associated with confined animal feeding operations. The winter feeding management strategies of grazed livestock can also have a significant seasonal impact on the quality of nearby surface water resources.

In northern regions, winter is a dormant season for forage and a time when significant precipitation can occur. In recent years EPA has clarified the regulatory definition of an Animal Feeding Operation (AFO). The winter feeding management practices employed by grazing operations may risk water quality resource concerns and meet the EPA definition of an AFO.

A planning tool to identify sites where livestock density during the winter feeding period could create a resource concern can facilitate addressing this water quality issue. This assessment tool can review the applicability of NRCS practices for an animal waste management system and if appropriate move the planning process forward for a site design to protect surface water quality resources as needed for the seasonal feeding period.

What did we do? 

As the Environmental Engineer at the West National Technology Support Center I am developing the planning tool for livestock winter feeding sites. The landowner can participate in developing the concerns to be considered for their natural resources and operational practices. Animal manure and the nutrient balance with forage crops can be checked. A review is made if the winter feeding operation approaches the EPA definition of an AFO. The buffer quality conditions can be checked between the feeding site and the surface water sources. This tool can help engage the landowner in a conversations about adaptive management options for pasture or waste storage facility structures as might be recommended for higher animal density management over winter.

What have we learned?             

Resource planning must include the concerns and values of the landowner and the practice must fit with the characteristics of their operation. Animal production and natural resource management is ultimately effected by landowner decisions for the management of livestock and protection of natural resources.

Getting Along With the Neighbors – Some Suggestions from Farmers


University of Wisconsin Extension hosted a meeting and part of the agenda was a discussion on neighbor relations. The farms represented at the meeting were large animal operations. They shared ideas on how they build or repair relationships with the community.

* During a recent power outage, we stopped by all of the neighbors with small children, offered the conference room at the farm as a warming shelter, as we have a generator on site that kept our power going.

* I provide a business card with my number to all of the neighbors and ask them to call me anytime with questions or concerns, allowing them to
also give me advance notice if they have a get together or event that our crews should be aware of. I say to call anytime they have a question
or concern. I stop by once per year, even to the neighbors who don’t like me.

* We do an annual training with our manure haulers, reviewing both the regulations we are under (243)/our maps, but also how we expect them to
act when representing our farm–etiquette expectations on the road-Jake braking, speed, being polite

* My clients are designating one person who does marking of setbacks in the field — biodegradable flags, spray paint, cones, even tillage that
shows where the setbacks area

* When a valve was left open on a tanker last fall, we bought car wash tokens and gave them to anyone driving through the area and those who
may not even have left home yet but lived on that road.

* We bought an industrial street sweeper and use it to clean mud and manure from the road

* After LISTENING to what the neighbors said in the hearing, some in my region are volunteering to observe larger setbacks to address neighbor
concerns. These can not be put into the permit and become enforcable, but it does show that they are open to the neighbor concerns.

* In January, I buy certificates for a maid service and hand deliver them to the neighbors. That way if our operations create dust, they can use it anytime during the year when they want to.

* We sponsor a local baseball team/soccer team, put the farm name on the back of the shirts, and after each game, provide chocolate milk to the winners “and non winners”

* We plow the snow from the ends of our neighbor’s driveways after each storm. It takes 5 minutes but they really appreciate it.

Biosecurity for Livestock and Poultry Manure Management

Most biosecurity plans are meant to protect animal and human health by preventing the spread of bacteria or other pathogens. Indirectly, effective biosecurity practices can reduce the likelihood of multiple or catastrophic mortalities which is an issue of environmental concern. While not usually discussed under the umbrella of “biosecurity”, manure handling should not be ignored when considering your plan. Related: Manure Pathogens

Avian Influenza | Swine PEDv | Pumping & Land Application | Inspectors | Mortalities | Recommendations by Species

Avian Influenza Resources

Since 2015, millions of birds have either died or had to be euthanized because of highly pathogenic avian influenza (HPAI). The approved methods of disposal for large-scale (catastrophic) mortalities include: burial, incineration, and composting.

PEDv (Porcine Epidemic Diarrhea virus) Resources

The swine industry has experienced significant losses as a result of PEDv, which can be transmitted through contact with manure of infected pigs. It is possible to move the virus between farms on vehicles, pumps, manure handling equipment, clothing, or any other item that comes in contact with manure and is not thoroughly disinfected between farms/fields. The low amount of viral exposure required to cause illness means that even tiny amounts of residual manure pose significant biosecurity risks.

Preventing Manure Pathogen Dispersal Between Farms or Field

Restricting access of off-farm equipment and personnel involved in manure pumping or manure application and thorough cleaning of equipment between farms are among the recommendations to follow to reduce risks of spreading manure-borne pathogens.

    • North Dakota State Biosecure Nutrient Management. This fact sheet does an especially nice job describing how to manage and clean equipment used in manure handling around the farm.
    • The National Pork Board released fact sheets on Biosecure Manure Pumping Procedures for farmers (pg 20), commercial manure haulers (pg 22), and land owners (pg 20).
    • The Maryland Department of Agriculture developed a brochure related to transporting manure and set out some guidelines to prevent the spread of pathogens.

Biosecurity for Inspectors or Technical Service Providers

What should regulatory inspectors do when traveling between farms to prevent the spread of disease? What requests can farmers make of inspectors to protect their farm biosecurity?

Biosecure Mortality Management

One of the best collections on composting animal mortalities comes from the Cornell Waste Management Institute. Check out their sections on health and safety and animal mortality composting for research on pathogen destruction and other safety considerations.

The following fact sheet was developed in response to the PEDv (porcine epidemic diarrhea virus), although these guidelines should be effective for reducing the risks related to other pathogens. It focuses on the use of rendering as the main mortality disposal method. Biosecure Mortalities Removal (pg 10)

Environmental Protection Agency (EPA) Perspective on Nutrient Pollution

Waste to Worth: Spreading science and solutions logoWaste to Worth home | More proceedings….

Why Discuss Regulations and Nutrient Pollution?

Provide EPA’s perspective on nutrient pollution and encourage an open dialogue to help address this problem which is rapidly becoming one of the most challenging environmental problems that we face.

What Did We Do?

Although nutrients, nitrogen and phosphorus in particular, are essential for aquatic life, too many nutrients can create significant problems for our nation’s lakes, streams, and coastal waters.  Nutrient pollution can degrade habitat for fish and wildlife, render water bodies unsafe for swimming and other forms of contact recreation, create a public health concern for drinking water supplies, decrease property values, and negatively impact local economies.  According to national statistics, more than 45% of streams have medium to high levels of nutrients, approximately four million lake acres have been identified as threatened or impaired, and approximately 78% of assessed coastal areas exhibit signs of eutrophication.

Nutrients can be transported great distances and impact areas far downstream.  One of the more prominent examples in the United States is the Gulf of Mexico “dead zone,” which can be larger than the state of Connecticut in some years.  The term “dead zone” refers to waters that have been so heavily impacted by nutrient pollution that oxygen levels are depleted to the point where most aquatic life cannot survive.  Nutrients are transported to the Gulf of Mexico via tributaries of the Mississippi River from as far away as Montana in the west and Pennsylvania in the eastern portion of this large watershed.

Nutrient pollution is not restricted to the Mississippi River Basin or any one region of the country.  Nutrient pollution is widespread, impacting waters across the nation.  As we learn more about the impacts of nutrient pollution, especially the potential for some species of algae to produce toxins that can be harmful to both people and animals, states are becoming more aggressive in reducing sources and even posting health advisories when necessary.

So, what has EPA been doing to address nutrient pollution?

  1. Providing states with technical assistance and other resources to help develop water quality criteria for nitrogen and phosphorus;
  2. Working with states to identify waters impaired by nutrients and developing restoration plans;
  3. Awarding grants to states to address pollution from nonpoint sources, such as agriculture and storm water runoff;
  4. Administering a permit program designed to reduce the amount of nitrogen and phosphorus discharged to the environment from point sources;
  5. Providing funding for the construction and upgrade of municipal wastewater treatment plants;
  6. Working with states to reduce nitrogen oxide emissions from air sources;
  7. Conducting and supporting extensive research on the causes, impacts, and best approaches to  reduce nutrient pollution; and
  8. Increasing collaboration with other federal partners (e.g., USDA) to leverage financial and technical resources.

And although progress has been made over the past decade, much more is needed.  Realizing a need for greater action, In March 2011, EPA issued a memorandum titled “Working in Partnership with States to Address Phosphorus and Nitrogen Pollution through Use of a Framework for State Nutrient Reductions.”  This memo emphasized that nutrient pollution continues to have the potential to become one of the costliest and most challenging environmental problems that we face and reaffirmed the agencies commitment to partner with states and stakeholders to make greater progress in reducing nutrient loading to our nation’s waters.  If you have not already done so, please join us in protecting and restoring our nation’s waters.  For more information visit EPA’s nutrient pollution website at http://www.epa.gov/nutrientpollution/.

Phosphorus Indices: Taking Stock of Where We Are and Where We Need to Be

Abstract

The inconsistency among P Indices in terms of level of detail and scientific underpinnings among states, as well as in recommendations and interpretations based on site risk, prompted a review and possible revision of the 590 Standard and P-Indexing approach.  The need for revision has been heightened by a slower than expected decrease in P-related water quality impairment and, in some cases, an increase in soil P to levels several fold greater than agronomic optimum due to the inability of the P Index to prevent the continued over-application of P to soils.  While the basic scientific foundations of the P-Indexing approach are sound, these concerns are real.  In this presentation, we propose the use of lower and upper boundaries of P Index use and describe an approach to evaluate individual State P Indices.

This research was key to framing the application of the Phosphorus Index in Nutrient Management Planning.   See N.O. Nelson and A.L.

Why Is It Important to Review the Phosphorus Index?

Since its inception nearly 20 years ago, the phosphorus (P) Index has morphed from an educational tool to a Best Management Practice targeting and implementation tool, a manure-scheduling tool, and in many cases, a regulatory tool.  A great deal of research has been conducted across the U.S. to derive, validate, and support components of the P Indexing concept, particularly those related to source factors.  As different versions of the P Index have emerged, ostensibly to account for local topography, hydrology, soils, land use, and individual state policies and agendas, so too have differences in the P management recommendations that are made using the P Index.  As a result, there are many variations in P Indices now in use as part of the NRCS 590 Nutrient Management Conservation Standard.  This variation is both a strength and weakness of the P Indexing concept.

Andrew Sharpley, Professor, Division of Agriculture, University of Arkansas System.  Sharpley was one of a core group of scientists that back in the early 1990’s developed the scientific foundation of the Phosphorus Indexing approach.  Since then he has conducted extensive field research to justify source and transport factors included in Indices, which have been adopted in 49 of 51 States to guide nutrient management planning as part of the 590 Standard.  He was instrumental in changing USDA and US EPA nutrient management planning strategies away from single numeric soil phosphorus environmental thresholds to the Indexing approach for risk assessment of phosphorus management and land application.  In the last year, he coordinated a group of researchers and extension folks from diverse backgrounds to review and propose revisions to Phosphorus Indices in compliance with the 2011 590 Standard.
