The objective of this three-year drag hose project is to establish yield reductions from using a drag hose on soybeans at various vegetative stages. Most liquid livestock manure in the western Lake Erie watershed is surface-applied in the fall without a growing crop. Manure is now being routinely applied to corn, both incorporated and surface-applied, up to the V4 growth stage. This project determines if this is an option in soybean fields, as well. This research explores the eventual application of livestock manure to emerged soybeans. It aims to determine the yield damage from fully loaded six-inch manure drag hose across soybeans after emergence at various growth stages and from the tractor dragging it.
