Applying fertiliser

This week’s sheep feature reports on a Teagasc Grass10 early spring walk. One of the main messages delivered was the importance of getting fertiliser applied as soon as weather and ground conditions permit. At €380/t, urea represents a cost of 82c/kg N. Taking the average spring nitrogen response of 10kg grass dry matter growth per 1kg nitrogen applied on productive swards, this equates to a cost of 8.2c/kg grass DM.
