A.The main advantage of splitting is it gives an opportunity to apply a small amount of nitrogen early in the season while reducing the risk of losses by not applying all the nitrogen early. For example a silage field that is not being grazed in Spring could get 40 units of nitrogen per acre in mid February to take advantage of any early growth and another 60 units in mid-March. If March arrives without the opportunity for an early split it is then advisable to apply all the nitrogen in one split.
