Optimization of com nitrogen nutrition under influence of nitrification inhibitor
The influence of nitrification inhibitor (NI) 3(5)-methylpirazole on soil nitrogen transformation, growth, development, and yield of com (Zea mays L.) grain were studied. It was found, that application of urea with nitrification inhibitor negatively influenced growth of nitriflers in the soil. It was recorded a decrease of nitrate nitrogen ratio in the soil that resulted in prolongation of the urea efficiency. As a result it was harvested additionally on average 0,5-1,0 t/ha (5-10%) of the com grain.
