This week's Conservation Tillage Conference in Ada, Ohio, is expected to draw more than 900 participants. The program will feature a day-long discussion with industry and university experts on improving Ohio’s water quality, particularly ways to keep phosphorus and nitrogen from impacting water resources. Nutrient management, cover crops and soil health and Solving the P (and N) problem are just a few of the sessions offered at the conference. SENR faculty experts, including Robyn Wilson, Steve Culman and Warren Dick, are scheduled to present their research.
A recent Columbus Dispatch article (12/22), "Curbing Fertilizer Runoff a Challenge" features Professor Warren Dick's research on gypsum and in particular how it captures phosphorus and prevents it from washing off the fields. Eugene Braig, program director for aquatic ecosystems in the SENR at Ohio State University is also quoted in the article.
Gypsum, which has roots in the past as a farm soil treatment, also may have a bright future, and not just as a booster of crops but also a protector of water. Warren Dick, a scientist in Ohio State University’s College of Food, Agricultural, and Environmental Sciences, is two years into a three-year study of gypsum’s benefits on farms, including to soil quality, crop yields and reducing phosphorus runoff.
ADA, Ohio – Growers who plant cover crops and vegetative systems in agriculture will find that it can tie up phosphorus in a stable phosphorus form that remains in the soil which can increase phosphorus use efficiency, according to a soil researcher from Ohio State’s College of Food, Agricultural, and Environmental Sciences.
