Does that mean that a grower should be applying some ‘starter N’ if he is treating his seedrow applied urea with AGROTAIN?
Applying some untreated urea or some other type of nitrogen as a source of starter N is unlikely to be beneficial for the following reasons: • In the early stages of growth, the greatest nutritional demands of the seedlings will be for phosphate(P). Since the usual source of seedrow fertilizer P will be ammonium phosphate, any P that is taken up by the young seedlings is most likely to be paired with some N. Therefore, at these early stages of growth, the plant will be obtaining adequate amounts of N from the P fertilizer. • Our soils are seldom totally devoid of readily available N. Therefore even if no seedrow P fertilizer is applied, there should still be adequate supplies of N present in the soil to meet the early N requirements of young seedlings, especially since these needs are minimal at a early growth stage. • Keep in mind that while the suppression of the conversion of urea to ammonium carbonate by AGROTAIN is very effective at the early stages, its control of the urease enzy
