Special Presentation on Soil Science
Dr. Libby Dayton, a soil scientist with the Ohio State University, will make a special presentation about her research at the November meeting of the Portage River Basin Council. The meeting is Thursday, November 6 at 2 p.m. at Wood Soil and Water Conservation District offices in Bowling Green. It is open to the public.
Dr. Dayton is engaged in edge of field studies on agricultural land. She is studying how particulate phosphorus found in farm fertilizers converts to dissolved reactive phosphorus. It is the dissolved reactive phosphorus that has been implicated in overgrowth of algae in lakes. Research shows that farmers are using less phosphorus in their fertilizers, yet the amount of dissolved reactive phosphorus in waterways has been increasing.
Dr. Dayton has been working to make the P-index more accurate, predictable and robust. The P-index is a measure of the efficacy of farmers’ efforts to reduce phosphorus transport. The goal of her work is to help farmers manage and reduce the risk of transferring phosphorus from their fields to the waterway. It is a complicated subject. According to reports from OSU, some topics she is considering include tillage strategies, soil type, fertilizer placement, soil phosphorus content, field topography, soil infiltration rate, drainage control structures, and cover crops.
