What are the differences and characteristics of compound fertilizers and compound fertilizers?
Compound fertilizer refers to a chemical fertilizer containing three elements of nitrogen, phosphorus and potassium or two elements. There are two production processes for compound fertilizer: one is a compound fertilizer produced by a physical mixing method; the other is a compound fertilizer formed by a chemical reaction.
Since the compound fertilizer and the compound fertilizer have little difference in fertilizer efficiency, in 2002, the relevant state departments issued new fertilizer production standards, and classified the compound fertilizer and the compound fertilizer into a large category. In comparison, the production cost of compound fertilizer is low, as long as the various basic fertilizers are matched and mixed well. The production of compound fertilizer needs to provide certain conditions for the chemical reaction of the raw materials, and then spray granulation, the cost is much higher than that of the compound fertilizer. As long as the nutrients are the same, the compound fertilizer and the compound fertilizer have little difference.
