A multiple staged digestion system capable of digesting drylot manures is currently under development. The system is currently being validated at the pilot scale with three 1.5 cubic meter batch reactors. The system shows promise with various animal manure wastes as well as other common waste products. …
Grid Soil Sampling to Guide Manure Application
Why Consider Grid Sampling for Manure Application?
Grid soil sampling for phosphorus and potassium can identify areas in fields with nutrient deficiencies and other areas with sufficient or excess nutrients. Nutrient maps can be used to define areas for manure application or exclusion, using supplemental fertilizer where manure is not applied or does not meet the crop requirements.…

Why Study Phosphorus Recovery?
Land application of manure in regions with intense confined livestock and poultry production is an environmental concern when land is limiting because it promotes soil phosphorus (P) surplus and potential pollution of water resources.…
Solid Manure Sampling Procedures
Developing a nutrient management plan depends on testing manure for nutrient content. Your manure test results are only as good as your sample. This page outlines recommended ways to sample solid manure from open feedlots.
Sample During Loading
The recommended sampling for solid manure is to sample while loading the spreader.…
Calibrating Solid Manure Application Equipment
Why should you calibrate solid manure spreaders? Simple, because you should know how much manure was applied to your fields. Combined with a manure testing program, you can calculate the amount of manure nutrients that were applied. This can save money on commercial fertilizer purchases AND improve water quality.…
Solid Manure Collection and Handling Systems
Solid manure is typically generated in systems where bedding is added to manure to absorb moisture and enhance environmental conditions in the production area. Solid manure can also result from drying conditions such as occur on the surface of a beef feedlot. Solid manure storage and handling is typically more forthright than liquid or slurry manure systems.…

How is solid manure applied to cropland?
The most common equipment for applying solids to the land is a rear-discharge, box-type spreader equipped with beaters that broadcast the manure over a width of several feet (see Image 1).…
Role of Solid Liquid Separation in Manure Storage
There are benefits for manure storage systems in separating manure into solid and liquid components. Solid-liquid manure separation is also a desirable first step in many systems used for manure treatment (composting, anaerobic digestion, etc.)
Solids Accumulation
Waste solids, particularly those from dairy freestall housing bedding, can accumulate quickly in waste storage ponds.…
Costs of Solid Manure Application and Transport
Poultry litter and beef feedlot manure are the most common types of “solid” manure. Separated solids from dairies can also be a source of solid manure. Solid manures must be scraped off the floor of the pen or house where the animals were raised. Scraping and loading onto trucks usually is done with a front end loader.…
Composting Livestock or Poultry Manure
Compost not only describes the completed degradation of a mixture of materials; it also denotes the process that materials undergo before becoming compost. A workable definition for compost is that it is an organic soil conditioner that has been stabilized to a humus like product, is free of viable human and plant pathogens and plant seeds, does not attract insects or vectors, can be handled and stored without nuisance, and is beneficial to the growth of plants.…
