At the New York locations, the Cornell team is gaining insight on the effects of tillage practice, cover cropping, management decisions of manure application and manure-based products, and value of manure on environmental and agronomic parameters including greenhouse gas (GHG) emissions, soil health, yield and forage quality.

Cornell University conducts research across three study sites in New York state: two in western New York and one in central New York. The sites in western New York are a large plot study, where the team compares five different management practices, and the nitrogen replacement study, where the team quantifies the amount of fertilizer nitrogen that can be replaced by different manure products and their potential impact on yield and forage quality. The site in central New York compares two different management practices across four yield stability zones. All of the study sites grow corn silage.

Spreader in field

"It is great to be able to work with producers that are interested in evaluating various management practices on their farm. Partnerships like this are essential to generating relevant questions and getting meaningful results."
- Quirine Ketterings, Principal Investigator

Slide

"If we’re going to change our practices, we need to understand the value. There’s a big focus on data in agriculture. But if you can’t use it, what’s the point? This data will help us better utilize our resources. That’s why we’re participating."
