Chef Tu explains the advantages and disadvantages of compound fertilizer.

Released Date: Nov 11,2021 Article Source: TDCU
Compound fertilizers generally refer to binary compound fertilizers synthesized by chemical methods, such as diammonium phosphate, potassium nitrate and potassium dihydrogen phosphate. The ternary fertilizer prepared by secondary processing is called compound fertilizer. Tu Chef Xiaobian thinks that by comparing compound fertilizers with simple chemical fertilizers, we can better understand the advantages and disadvantages of compound fertilizers.

I. Advantages of compound fertilizer

1There are many kinds of nutrients with high content. Compound fertilizer contains many kinds of nutrients and high content of effective components. For example, diammonium phosphate is a kind of18-46-0Compound fertilizer, said the fertilizer is nitrogen (N)18%, phosphorus (P205)46%Binary compound fertilizer. It has more kinds of nutrients and higher content than simple nitrogen or phosphorus fertilizers.

2Good physical properties and convenient application. The particles of compound fertilizer are relatively firm, dust-free, uniform in particle size and small in hygroscopicity, which is convenient for storage and application. Compound fertilizer is not only suitable for mechanized fertilization, but also convenient for manual application.

3And no adverse effects on the soil. Simple chemical fertilizers generally contain a large number of secondary components. For example, ammonium sulfate only contains20%Nitrogen, which contains a large amount of sulfate as a by-component, except for a few sulfur-deficient soils that need to be supplemented with sulfur, most of the sulfate remains in the soil, resulting in waste of sulfur resources; butcomplex fertilizerAlmost all or most of the nutrients are needed by crops and can be absorbed and utilized by crops. Due to the small number of secondary components, the basic influence on soil properties is relatively small.

Second, the disadvantages of compound fertilizer

1And the nutrient ratio is fixed, so it is difficult to meet the needs of crops. Many crops have different nutrient requirements in different growth stages, and the soil fertility and nutrient release conditions in different regions are also very different. Therefore, the compound fertilizer with relatively fixed nutrient ratio is difficult to meet the requirements of all kinds of soils and crops at the same time.

2The release rate of various nutrients is out of step with crop requirements. The movement rules of the main nutrients in the soil are different. For example, the mobility of nitrogen fertilizer is greater than that of phosphorus and potassium, but the aftereffect of fertilizer is far less than that of phosphorus and potassium. Therefore, it is difficult for compound fertilizers to fully meet the special requirements of crops for nutrients in a certain period in terms of nutrient location and release speed.

Shandong Tudachu Fertilizer Co., Ltd. is a high-tech enterprise introduced by the government, which integrates the research and development, production, sales, foreign technology introduction and import agency of microbial agents, water-soluble fertilizers and fully water-soluble tower compound fertilizers. It is supported by a full set of functional fertilizer products, scientifically nourishes every cycle of crop growth, and provides a variety of high-tech products. According to the different conditions of different crops, nutrition cares for every link of crop growth, effectively solves the problem of crop nutrient deficiency, and enables crops to grow healthily and obtain higher quality and more output.
