Brief Project Summary:

Over the last several growing seasons, the soil fertility and nutrient management program has found pelletized chicken manure to offer fairly consistent yield increases in both soybean and corn production. While the yield increases have not always been statistically significant, consistent trends in greater yield and greener, increased plant vigor have been observed. A disadvantage of this product is price and growers need more focused data on how much to apply and which crop to apply this product to.

Recent data from the upper Midwest has shown that only 20% of soybean producers apply P prior to the soybean rotation. As soybean yield and perhaps more importantly soybean biomass have...

Information And Results
Project Deliverables

Measurable will include 1) plant height and SPAD readings at V3-4 and R5, 2) Soy tissue sampling at R1, and 3) grain yield and moisture. All studies will be highlighted for summer research tours and discussed at appropriate extension meetings.

Final Project Results

Updated February 21, 2017:
No individual input beneficial for enhanced or traditional management
All inputs resulted in gross profit increase when removed
All inputs resulted in gross profit decrease when added
Lack of individual input response in 2016
Lack of nutrient deficiencies, disease
Enhanced and Traditional produced similar yields
Traditional +65% more gross profit than Enhanced

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
