Grass Hay Fertilization

As grass hay harvest gets underway we need to be thinking about fertilizing those stands with nitrogen (N). The most efficient way to fertilize these grass hay stands is to split apply N based on the expected yield of the next growth. The actual rate should be 50 lb N/ton of expected hay yield. Fertilizer should be applied as soon after cutting as practical. All of our common N fertilizer materials work well. If urea or UAN are used, applying these right before rain will help to minimize N volatilization loss.
