Nitrogen fertilizer is used skillfully, economically and efficiently.
First, the effect of nitrogen conservation is good. Changing nitrogen fertilizer from surface application to deep application can greatly reduce the volatilization loss and denitrification of nitrogen fertilizer. Reduce the consumption of fertilizer by weeds and algae, so that the nitrogen fertilizer has a good effect on nitrogen conservation. The nitrogen fertilizer was deeply applied to 7ml / 5cm. According to the determination, ammonium bicarbonate ball fertilizer was applied deeply, and the nitrogen loss was 3% 30 days after fertilization.
