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. The Soil Fertility Lab has two new graduates!

    Apr 30, 2019

    We are excited to announce that the Culman Lab has two new graduates! Congratulations to Jordon Wade and Noely Gonzalez-Maldonado on completing their graduate degrees. Jordon's PhD dissertation, entitled "Soil Health and Nutrient Dynamics in Agroecosystems of the Midwestern US", focused on elucidating how soil health measurements influence and are influenced by fertilizer applications. Noely's MS work, entitled "Evaluating the Effects of Long-Term No-Till and Crop Rotations in Soil Health and Corn Productivity, focused on determining the effects of half a century of continuous no-till and crop rotation on soil health and its relationship with crop productivity. Both theses will be made available on our website soon!
