The national winners represent farmers and fertilizer retailers across the nation dedicated to the 4Rs of nutrient stewardship — using the right nutrient source, at the right rate, at the right time and in the right place.
Ohio workshop to focus on reducing off-site movement of soluble nutrients
Farmers who plant cover crops and vegetative systems will find that it can tie up phosphorus in a stable form that remains in the soil, which can increase phosphorus use efficiency, says a soil researcher from Ohio State's College of Food, Agricultural, and Environmental Sciences.
That, and the question of whether agriculture can significantly reduce off-site movement of other soluble nutrients, will be discussed by Ohio State University Extension, the Ohio Agricultural Research and Development Center and industry experts in agriculture, climatology and environmental economics during a workshop hosted by the Soil and Water Conservation Society on March 17.
The daylong workshop will focus on discussing technologies and techniques to reduce off-site movement of nutrients and the barriers to their adoption and implementation, said Jim Hoorman, an OSU Extension educator and an assistant professor studying cover crops and water quality issues.
"Recently collected Ohio soil test data using phosphorus speciation is showing that phosphorus is tied up by calcium/magnesium, iron oxides, and aluminum oxides," said Hoorman, who will discuss "New Ohio Data on Cover Crops and Phosphorus" during the event. "However, under certain environmental conditions (saturated soils, no oxygen), the iron oxide is being reduced by the soil microbes hungry for oxygen, releasing soluble reactive phosphorus."
