What is the difference between compound fertilizer and simple fertilizer?

What is the difference between compound fertilizer and simple fertilizer? Compound fertilizer refers to chemical fertilizer containing nitrogen, phosphorus and potassium or only any two of them. The advantages of compound fertilizer can be summarized as follows: comprehensive nutrients and high content. Nutrients in each compound fertilizer are evenly distributed, which not only provides the best nutrients for crops, gives full play to the mutual promotion between nutrient elements, but also has balanced nutrient release, stable fertilizer efficiency and long fertilizer supply time, so it usually has good fertilizer efficiency. Easy to use. Compound fertilizer particles are relatively solid, dust-free, uniform in size, small in moisture absorption, easy to store and use, suitable for mechanized fertilization, but also easy to spread manually. There are few side components and no adverse reactions to soil. Simple fertilizer generally contains a large number of secondary components, such as ammonium sulfate only contains 20% nitrogen, and a large number of sulfate roots in addition to the lack of sulfur in the soil, applied to the soil is a waste. Almost all or most of the nutrients of the compound fertilizer are required by plants, thus avoiding waste of resources and adverse effects of side components. Most compound fertilizers contain calcium, which has less effect on soil acidification than simple fertilizers. The compound fertilizer has various proportions and can be selected and applied in a targeted manner. Compound fertilizer is made by secondary processing according to the requirements of farmers according to the soil nutrient status and crop fertilizer demand characteristics. Therefore, the nutrient proportion of compound fertilizer products is diversified, and many expenses can be saved and labor can be reduced in fertilization practice.
