Smart ways to use nitrogen fertilizer: economical and efficient application
1. Good nitrogen retention. Changing nitrogen fertilizer from surface application to deep application can greatly reduce volatilization losses and denitrification. It reduces fertilizer consumption by weeds and algae, giving nitrogen fertilizer a good nitrogen-retention effect. Apply nitrogen fertilizer 7--9 cm deep. According to measurements, when ammonium bicarbonate spherical fertilizer is applied deep, 30 days after fertilization the nitrogen loss is 3...
