Statewide Iowa (RI) — Midwestern corn growers are testing whether they can use less fertilizer and still maintain yields or improve their bottom line through on-farm research trials. It’s part of an ongoing project led by Practical Farmers of Iowa that’s designed for producers who use cover crops, no-till, and other practices to boost soil health. Kevin Prevo, who grows crops and raises livestock in Davis County, says this will be his fourth year of taking part in the trials.
It’s an easy process, he says.
Prevo says he appreciates being able to see how other farmers respond to the nitrogen rate research trials.
Participants apply their typical nitrogen fertilizer rate and a reduced rate in randomized strips in their fields, and share data about their yields, costs, and profits. A coordinator at Practical Farmers of Iowa says enrollment in the program will likely stay open until early April. Farmers who participate receive compensation.
