Development and Application of the Newtrient Evaluation Assessment Tool (NEAT):  A Methodology for Comparing Manure Treatment Technologies

The recent development of the Newtrient on-line catalog (www.newtrient.com/Catalog/Technology-Catalog; see accompanying conference proceedings about the catalog) revealed the need to establish a set of environmental and farm operational based critical indicators (CIs).  The indicators are useful in identifying manure treatment technologies that primarily best address dairy farm environmental sustainability but include some social aspects.

Considerations in Evaluating Manure Treatment Systems for Dairy Farms

Advanced manure treatment may become a major system on some dairy farms in the future.  Reducing the impacts of excess nitrogen and or phosphorous may be necessary on farms with a limited or remote land base.  Additional treatments to recover solids, extract energy, concentrate nutrients, reduce odors, reduce the mass/volume, and/or reduce pathogens may become more of a priority as farms seek to move toward sustainability.  

NRCS Solid-Liquid Separation Document – It is Finally Here!!

NRCS has a new technical document entitled “Solid-Liquid Separation Alternatives for Manure Handling and Treatment.”  It was created through efforts from Dr. John Chastain, Clemson University with funding provided by USDA-NRCS.

This document brings together both the theory behind solid-liquid separation and the practical application of many different separation technologies.  

Minnesota’s Runoff Risk Advisory Forecast: Forecasting the optimal time for manure application

The Runoff Risk project was started in Wisconsin in 2011, with the realization at that time, there was no real-time runoff risk guidance available for manure applicators. The project has grown, with four states (Michigan, Minnesota, Ohio and Wisconsin) now operating real-time runoff risk forecast websites.

Regional Runoff Risk Tools for Nutrient Reduction in Great Lakes States

One method to reduce the impacts of excess nutrients leaving agricultural fields and degrading water quality across the Nation is to ensure nutrients are not applied right before a runoff event could occur.  Generally nutrient management approaches, including the 4-Rs (“right” timing, rate, placement, and source), include some discussion about the “right time” for nutrient applications, however that information is static guidance usually centered on the timing of crop needs.

Purpose 

Over the past four decades, the number of custom slaughterhouses in Michigan has steadily decreased as the number of livestock producers declined. Those who remain are growing larger as they capitalize on the buy local food craze by providing fresh USDA-approved boxed meats at a meat counter or by adding value to the meats by further processing (i.e.,…
