Project Overview
Organic grains fetch a substantial price premium and demand for organic feed grains far exceeds domestic supplies, creating a strong market incentive for grain farmers to go organic. Challenges include learning how to farm without synthetic inputs, greater reliance on tillage, excess P accrued with manure-based fertility, and lower yields sold at conventional grain prices during the three-year transition period.
This project evaluated four transition strategies: perennial alfalfa-grass hay (no tillage), and an oat-corn-soy rotation with cover crops and minimal, reduced, or full schedules. Field trials were completed at three sites and certified organic corn was grown in year 4 after all treatments. Soil health parameters, nutrient losses, crop yields, and net economic returns were documented.
Farmer Takeaways
(1) Reducing tillage during the three-year transition period improves soil health outcomes and reduces erosion risks.
(2) Growing perennial forages for hay during the transition may enhance soil health, corn yields in the first certified organic year, and economic viability of the transition.
(3) Suitable and correctly adjusted planters are essential for seed-soil contact, crop establishment, and viable yield in minimum-till organic grain crop production.
(4) Timely (ASAP after harvest) cover crop planting is essential for soil health benefits. Deep-rooted cover crops planted early in fall can recover all soluble N to 5-7ft depth.
(5) A high-biomass cover crop mix of grass, legume, and crucifer can substantially enhance soil P, Ca, Cu, Zn, and Mn, and may make P applications unnecessary.
