Compound fertilizers and compound fertilizers can cause losses in different fields. Compound fertilizers and compound fertilizers are two different types of chemical fertilizers. The price and fertilizer efficiency of the two are far apart. Compound fertilizer refers to a chemical fertilizer containing three elements of nitrogen, phosphorus and potassium or two elements.

1. Different production processes The compound fertilizer is synthesized by chemical reaction, and its nutrient content is uniform and the particle size is consistent. The compound fertilizer is formed by physical mixing, the production process is simple, the nutrient is uneven, and the effect is poor.
2. The nutrient utilization rate is different. The chemical fertilizer synthesized compound fertilizer has uniform nutrient release and high utilization rate. However, the physical mixed compound fertilizer releases unbalanced nutrients, which is easy to cause waste and lack in the process of crop absorption.
3. Different implementation standards No matter whether it is compound fertilizer or compound fertilizer labeled as compound fertilizer, it is generally marked as GB15063-94, while the marking standard of compound fertilizer is different, which is the enterprise standard for implementation. You can discern it with a little attention when you buy it. Where the marking standard is GB15063-94, and the total nutrient does not exceed 30%, it is a compound fertilizer.

Since the difference in fertilizer efficiency between compound fertilizer and compound fertilizer is not very large, in 2002, the relevant state departments issued new standards for fertilizer production, and classified compound fertilizers and compound fertilizers into one category. In comparison, the cost of compound fertilizer production is low, as long as the various basic fertilizers are matched and mixed well.

Compound fertilizer production needs to provide certain conditions for the chemical reaction of raw materials, and then spray granulation, the cost is much higher than that of compound fertilizer, so whether to buy compound fertilizer or buy compound fertilizer, depends on their The nutrient content is not what you need, and the price is right.

As long as the nutrients contained are the same, there is little difference between compound fertilizer and compound fertilizer. When purchasing compound fertilizer, it mainly depends on whether there is agglomeration. Most of the fertilizer agglomeration has no effect on the use effect, but it has an impact on the use process. And buy compound fertilizer to see if the particle size is uniform.
