AMES, Iowa – Soil health and water quality benefits associated with organic farming will be the topic of the Iowa Learning Farms webinar at noon on Wednesday, April 21.
Kathleen Delate, professor and extension organic specialist in horticulture and agronomy at Iowa State University, will share research results that show greater soil and water quality benefits in organic systems with longer crop rotations, when compared to conventional corn-soybean rotations.
Small grains and perennial legume species, like alfalfa, are integral to supporting greater soil microbial populations and aggregate stability. Certified organic production requires the use of slower-release forms of nitrogen, which are associated with less nitrate loading and improved water quality.
“Returns have (frequently) been negative in conventional row crop farming in recent years; alternatives that consist of longer crop rotations with lower inputs and improved soil and water quality need to be explored,” said Delate, who is responsible for research, extension and teaching in organic agriculture at Iowa State University. “Give organics a go. You might be surprised to see how your soil changes and how many more pollinators and beneficial insects show up on your farm!”
