Fertilizer's acidity and alkalinity and reasonable fertilization

Rational application of chemical fertilizers can greatly increase crop yields. How do you use fertilizers rationally? This must understand the acidity and alkalinity of fertilizers. When buying and using chemical fertilizers, you must first understand the acidity and alkalinity of the fertilizer. The acidity and alkalinity of chemical fertilizers can be divided into two kinds: chemical acid bases and physiological acid bases. Fertilizer acidity and alkalinity refer to the acidity and alkalinity of the fertilizer dissolved in water. According to this definition, the fertilizer can be divided into chemical acid fertilizer, chemical alkaline fertilizer, chemical neutral fertilizer. Ammonium sulphate, superphosphate, etc., soluble in water, acidic or weakly acidic fertilizers are chemical acidic fertilizers; ammonia, potassium carbonate, etc., soluble in water, alkaline or weak alkaline fertilizers are called chemical alkaline fertilizers; Ammonium, potassium sulfate, and calcium nitrate, which are neutral or nearly neutral in water, are called chemical neutral fertilizers. Physiological acidity refers to the acidity and alkalinity of the soil after the fertilizer is applied to the soil and absorbed by the crop. According to the different acidity and alkalinity in the soil after the fertilizer is applied, the fertilizer can be divided into physiological acid fertilizer, physiological alkaline fertilizer and physiological neutral fertilizer. Ammonium sulfate is a commonly used nitrogen fertilizer that can be decomposed into ammonium and sulfate ions in soil after application. Although both of these ions can be absorbed and utilized by plants, the amount of ammonium ions absorbed by plants is much greater than that of sulfuric acid. Root, so most of the sulfate is left in the soil. When the plants absorb ammonium ions, they release hydrogen ions, making the soil acidic acidic fertilizer. After sodium nitrate, calcium nitrate and other fertilizers are applied to the soil, the soil is rendered alkaline by the absorption and utilization of plants, and thus it is called a physiological alkaline fertilizer. Ammonium bicarbonate, urea, etc., applied to the soil and absorbed by plants, the soil presents a neutral or near-neutral fertilizer, called physiological neutral fertilizer. When people purchase chemical fertilizers to fertilize crops, they must determine the types of chemical fertilizers to be applied according to the acidity and alkalinity of the soil, the sensitivity of plants to acids and alkalis, and the conditions of water pouring so as to increase the efficiency of fertilizers and rationally apply them. Neutral soil generally does not choose fertilizer, as long as pay attention to fertilizer technology can better play the effect of fertilizer. However, soils that are too acidic or too alkaline are not only unfavorable to crop growth, but they also force the effectiveness of most nutrients in the soil solution to be reduced. Fertilizer fat supply becomes worse. In order to make use of the economics of fertilizers, it is necessary to use acidic or physiological acidic fertilizers, such as ammonium sulfate and superphosphate, in alkaline soils, and alkaline or physiological alkaline fertilizers, such as calcium nitrate, in acidic soils. Its role is to neutralize and adjust the acidity and alkalinity of the soil through the acidity and alkalinity of the fertilizer so as to gradually convert it to the neutral direction, so as to increase the solubility, availability, and effectiveness of fertilizer nutrients. This is also an important measure to improve the soil. one. Conversely, if acid fertilizers are applied to acid soils for a long period of time, the soil will be acidified, plated, and branched. On calcareous or alkaline soils, alkaline or physiological alkaline fertilizers will cause soil problems. Salt and alkalinization, structural deterioration, and fertility degradation.
