Title: Does Late Fall Manure Application Into Cover Crops Change the Manure Nitrogen Credit?
Principle Investigator: Matt Ruark
Objective:
1) To assess how manure application practice in the late fall affects the optimum N rate.
Funding Level: $16,951
Duration: 2 year
Title: Nitrogen Management on Sandy Soils: Missing Gaps in Knowledge
Principle Investigator: Matt Ruark
Objectives:
1) Determine the difference in optimal N rates for corn following corn or soybean.
2) Determine the benefit or limitation of emergence applied PCU for corn based on change in field or optimal N rate.
3) Determine the benefit or limitation of alternative PCU application strategies on corn yield.
4) Determine if N application timing is beneficial to soybean.
5) Determine the relationship between fertilizer application and reduction in N fixation for soybean.
Funding Level: $73,516
Duration: 3 year
Title: Investigation of Soil Health N Tests to Predict Corn N Need
Principle Investigator: Carrie Laboski
Objective:
1) To evaluate the ability of soil health tests and soil properties to predict corn N need using archived soil samples from various N response studies over the past 11 years.
Funding Level: $138,911
