Over 527,000 acres of unmanaged woodlands are being used for livestock grazing throughout Minnesota. Managing these grazed woodlands based on the use of best management practices can provide environmental and economic opportunities, including improved water quality, maximized forage production, and higher-quality timber. The best management practices involved are commonly used in other parts of the country with other types of ecosystems, but have not been widely adopted in Minnesota due to a lack of knowledge and experience with implementing them within the ecosystems of Minnesota.
Funding supports an Irrigation Specialist to develop guidance and provide education on irrigation and nitrogen best management practices (BMPs). In this position, Dr. Vasu Sharma provides direct support to irrigators on issues of irrigation scheduling and soil water monitoring. She is collaborating on the development of new irrigation scheduling tools that help irrigators manage water and nitrogen resources more precisely. These tools help reduce nitrogen leaching losses in irrigated cropping systems.
This project will provide a better understanding of nitrogen fertilizer management on irrigated, sandy soils that are common in central and west-central Minnesota.
