Dairy

“On a poorly drained no-till Wisconsin field, surface-applied composted or fresh dairy manure (81-102 kg total N/ha) did not match sidedressed urea at 90 kg N/ha for corn yield or nitrogen uptake, and left lower plant-available N in the top 10 cm. An interseeded annual ryegrass cover crop cost nothing in yield or N uptake and cut nitrate-N leachate concentrations by 1.7-4.9 times.”
