Farmers’ shift away from fall application of nitrogen for crops such as corn and sorghum is being reflected in changing retail practices, says Farm Journal Field Agronomist Ken Ferrie. “In my area of central Illinois, I know two fertilizer plants that have completely dropped anhydrous ammonia,” he says. “Their sales had shifted to spring application of nitrogen solution. While ammonia can be applied in the spring, farmers found it took up too much of their time when they needed to concentrate on planting, compared to nitrogen solution that can be applied as they plant or with herbicides.”
