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.


  1. Soil Balancing Call-in Conversations

    Oct 2, 2018

    Soil management not only impacts crop yields, but also has a huge impact on the environment. For organic farmers, soil balancing has become a widely used method for soil management. Soil balancing is done by managing base cation saturation ratios, which can be an overwhelming concept to understand. As such,  our multidisciplinary team at Ohio State University is offering several opportunities for people to participate in phone-in events designed to provide conversations about the basis and practice of soil balancing. Researchers will be on hand to provide input and answer questions but the main focus will be to hear from callers and learn from their experiences. The phone-in conversations are a three-part series beginning this month. Click on the heading to view more information.
