Powdered ammonium sulfate is a commonly used nitrogen fertilizer that contains a high concentration of nitrogen nutrients and is commonly used to promote crop growth and increase yield. However, for rice cultivation, whether it is suitable to use powdered ammonium sulfate fertilizer needs to consider a series of factors, including soil environment, nitrogen requirements, fertilizer utilization efficiency and so on.
Firstly, powdered ammonium sulfate can provide sufficient nitrogen source in rice cultivation. As a fertilizer containing high nitrogen concentration, powdered ammonium sulfate can satisfy the nitrogen requirement of rice. The nitrogen required for rice planting is mainly used for the growth and development of leaves and stems, as well as the formation of flower pods and grains, so moderate nitrogen application can promote the growth process of rice and improve the yield.
Secondly, powdered ammonium sulfate can provide an acidic environment and improve soil acidity. Rice has strong adaptability to acidic soil, and powdered ammonium sulfate will produce acidic substances when the fertilizer dissolves and reacts, which can neutralize the alkalinity of the soil, thus improving the acid-alkalinity of the soil and conducive to the absorption of nutrients by rice roots.
However, it is important to note that excessive application of powdered ammonium sulfate can have a negative effect on rice. Nitrogen is an essential nutrient for the growth and development of rice, but excessive nitrogen will lead to a series of problems, including lodging resistance reduction in the stem, easy occurrence of diseases and pests, and quality decline of rice. Therefore, when applying powdered ammonium sulfate, it is necessary to control the fertilizer amount reasonably according to the soil fertility and the growth needs of rice.
In addition, the fertilizer utilization efficiency of powdered ammonium sulfate is also one of the factors worth considering. Because rice has a long growth cycle and developed root system, it requires relatively high nitrogen absorption and utilization. However, powdered ammonium sulfate is applied in granular form, which can not be well combined with the soil and is easy to be leached and lost, which reduces the fertilizer utilization rate. Therefore, powdered ammonium sulfate can be considered to be used together with organic fertilizer to improve fertilizer utilization efficiency.
In summary, the applicability of powdered ammonium sulfate as nitrogen fertilizer in rice planting needs to consider several factors. Under suitable soil environment, proper use of powdered ammonium sulfate can provide sufficient nitrogen source for rice, and promote the growth and yield increase of rice. However, care needs to be taken to control the amount of fertilizer applied to avoid the negative effects caused by excessive fertilization. In addition, reasonable collocation of other fertilizers and improving fertilizer utilization efficiency are also an effective way to use powdered ammonium sulfate fertilizer. The final decision should be made according to the actual situation and the advice of professional and technical personnel.
