Rigging The Race: Grower converts his anhydrous rig to speed liquid nitrogen application

摘要

Faster, easier, safer - and less power. It's for those reasons that Wood River, NE, farmer Kenny Layher converted his 13-knife anhydrous ammonia rig to a 16-row liquid fertilizer applicator. The benefits more than outweigh the higher cost of nitrogen(N) in solution vs. that of anhydrous ammonia, Layher says. He farms in a groundwater quality management area, where potential for nitrate leaching to the groundwater is high. Regulations prohibit fall preplant N applications. Instead, he's required to delay N application on his irrigated corn until after March 1 to shorten the time between N application and crop uptake.
