Welcome to the Soil Fertility Lab's website. Our work focuses on determining timely and efficient use of fertilizers, developing farmer-friendly soil health tests, and understanding how long-term management strategies can build organic matter and soil productivity. We engage and work collaboratively with farmers, crop consultants, and educators on a wide variety of soil fertility and management issues.

  3. Soil Fertility and Nutrient Management in Hops

    Feb 4, 2019

    The Soil Fertilty Lab is looking for hop growers to participate in our new research project. Details on the project, as well as cooperator involvement, can be found here. This is a two-year study that we hope to expand upon with further research after completion. Inputs from growers, as well as our advisory committee consisting of select regional growers, will form future research questions. We look forward to establishing a strong connection with the hop growers of the North Central region and working with you to answer questions and establish best practices in hop soil fertility and nutrient management.
