Wisconsin Enhances Soil Health Through Nitrogen Optimization Pilot Program
WEST BEND, Wis. – In its third year, Wisconsin’s Nitrogen Optimization Pilot Program (NOPP) aims to enhance soil health while addressing crucial environmental concerns regarding nitrogen use. Nitrogen is vital for plant growth, but excessive application can lead to groundwater contamination and pollution. Lindsay Rushford, program coordinator, emphasizes the initiative’s goal to reduce harmful nitrates for healthier ecosystems.
Allen Dornacker, a participant in the program, is utilizing manure as a natural nitrogen source on his 30 acres of rye, planted specifically as a cover crop to enrich the soil. The rye’s roots will absorb nitrogen, benefiting subsequent corn crops. "Nitrogen is expensive and over-application can hurt yields, so participating in this study enhances efficiency," Dornacker noted.
Monica Schauer, the research director from the University of Wisconsin, is analyzing the effectiveness of manure and cover crops compared to traditional chemical fertilizers. She acknowledged that fields with a history of manure may benefit more than previously recognized.
Dornacker’s dual goal of fertilizing his crops while feeding his 350 dairy cows highlights the program’s sustainable agricultural approach. Enthusiasts interested in similar projects can find more information through the Wisconsin Department of Agriculture, Trade and Consumer Protection.
