Fertilizer fertilizers generally refer to commercial fertilizers processed through chemical reactions. Compared with organic fertilizers, fertilizer fertilizers have the advantages of high nutrient content, rapid fertilizer efficiency, and ease of transportation. First, fertilizer classification. There are many ways to classify fertilizers. There are two more commonly used methods. One is to divide the nutrient elements contained in chemical fertilizers; the other is to classify fertilizers according to their speed. 1, according to the classification of nutrients contained in fertilizers. According to the classification of nutrients contained in chemical fertilizers, chemical fertilizers are classified into nitrogen fertilizers, phosphate fertilizers, potash fertilizers, trace fertilizers, and compound fertilizers. Among them, nitrogen fertilizer, phosphate fertilizer, and potassium fertilizer contain one of the three elements of fertilizer, and they are called "single fertilizer" or "unit fertilizer." Compound fertilizer is a fertilizer containing two or more nutrients in three elements. It contains two kinds of fertilizers called “binary compound fertilizers†and contains three kinds of fertilizers called “ternary compound fertilizersâ€. ". Compound fertilizers, among the three nutrients of nitrogen, phosphorus, and potassium, fertilizers made of chemical methods and/or blending methods with at least two nutrient-marked amounts. Including compound fertilizers, blended fertilizers, organic-inorganic compound fertilizers. Compound Fertilizer Among the three nutrients of nitrogen, phosphorus, and potassium, there are at least two kinds of nutrient-marked chemical fertilizers, which are compound fertilizers. Mixed fertilizer, nitrogen, phosphorus, potassium three kinds of nutrients, at least two kinds of nutrients labeled by the dry mix method of fertilizer, is a compound fertilizer. Organic-inorganic compound fertilizer, containing a certain amount of organic compound fertilizer. 2, according to the efficiency of chemical fertilizer classification. According to this method, chemical fertilizers are divided into quick-acting fertilizers and slow-acting fertilizers. Fast-acting fertilizers refer to fertilizers that are quickly absorbed and utilized by crops, such as nitrogen fertilizers (other than lime nitrogen), water-soluble phosphate fertilizers, and potash fertilizers; slow-acting fertilizers are fertilizers that are slow to absorb and utilize crops, such as calcium, magnesium phosphate fertilizers, and phosphate rock fines. , steel slag phosphate fertilizer.
