How does agricultural ammonium bicarbonate improve fertilizer efficiency?
How does agricultural ammonium bicarbonate improve fertilizer efficiency? Please guide agricultural ammonium bicarbonate soluble in water, its nitrogen content is low (17%), easy to decompose and volatilize at room temperature. Scientific application of ammonium bicarbonate can effectively improve its fertilizer efficiency, and the correct application of ammonium bicarbonate is very beneficial to crop growth. Although ammonium bicarbonate is easy to decompose to produce volatile ammonia, and the higher the temperature, the more water content, the faster the decomposition. However, ammonia vapor is easy to be carbonized and dissociated in soil solution, and absorbed by soil particles and organic matter, which can avoid leaching. Therefore, first of all, it is necessary to apply fertilizer according to this characteristic, no matter dry or wet, it is suitable for deep application, generally 6-8 cm, ploughing or covering the soil immediately after application; if it cannot be applied deeply, it should be combined with irrigation. With the application of ammonium bicarbonate, the paddy field can maintain a water layer of 7 cm and 10 cm. After sprinkling ammonium bicarbonate, it will not fall into the water for 2 to 3 days, but it is necessary to avoid burning the plants. In addition, ammonium bicarbonate should be used in low temperature season for dry crops, mainly as base fertilizer. Secondly, the deep application of ammonium bicarbonate is a good way to reduce the volatilization loss of ammonia and improve and prolong the fertilizer efficiency. Thirdly, ammonium bicarbonate is easy to decompose in case of alkali, so it can not be mixed with lime, plant ash or alkaline phosphate fertilizer, so as to avoid the loss of ammonia. Finally, in order to improve the utilization rate of ammonium bicarbonate, it should be used in conjunction with phosphorus, potassium and some trace elements and medium element fertilizers to maintain the balance of nutrients needed by crops.
