Ammonium bicarbonate is abbreviated as ammonium bicarbonate and it is still one of the major nitrogen fertilizers in China. The biggest drawback of this type of nitrogen fertilizer is chemical instability and high volatility loss. Farmer friends call it a gas fertilizer. Friends of the farmer's friends used to deposit ammonium bicarbonate on the surface. Due to the effect of moisture in the soil, the ammonium bicarbonate will decompose quickly and cause the loss of nitrogen volatilization. Therefore, the utilization rate is not high. This is the root cause of the low effectiveness of the ammonium bicarbonate fertilizer. . The application of ammonium bicarbonate should follow the principle of “deep application of soilâ€. The fertilizer is applied to a depth of about 6 cm. The characteristics of soil particles are generally negatively charged, and ammonium ions dissociated from ammonium bicarbonate are adsorbed, so that nitrogen is preserved and losses are reduced. The role. However, under special circumstances, such as when it is difficult to apply deep-seated cover crops, it is possible to combine irrigation immediately after spreading and reduce losses as much as possible. This is a last resort. HEBEI PINGLE FLOUR MACHINERY GROUP CO., LTD , https://www.plrollermill.com
