News article: New Ohio State Research Shows Phosphorus Levels in Ohio Soils Trending Downward
This news article was originally published on the website of the College of Food, Agricultural, and Environmental Sciences. COLUMBUS, Ohio — Agricultural soil phosphorus levels held steady or trended downward in at least 80 percent of Ohio counties from 1993 through 2015, according to recent findings from the College of Food, Agricultural, and Environmental Sciences at The Ohio State University.

Maintaining soil phosphorus levels in accordance with the research-based Tri-State Fertility Recommendations helps lower the concentration of phosphorus in agricultural runoff, according to ongoing research by SENR research scientist Libby Dayton. Because erosion matters, the phosphorus associated with eroded soil can be curtailed by reducing soil disturbances such as tillage and by maintaining field cover either as crop residue or as a growing crop, she said.
