First, the production process
Compound fertilizer, as the name suggests, is to mix several fertilizers in a certain proportion, and then granulate them by pulverization and mechanical mixing. The process is relatively simple, and the general production equipment investment is not large, mostly used by small and medium-sized fertilizer manufacturers.
Compound fertilizer is the synthesis of new substances by chemical reaction in several proportions, and is formed by granulation. Production equipment investment is large. Generally, small fertilizer enterprises cannot produce them.
Second, nutrient content
The nutrient content of the compound fertilizer can be arbitrarily adjusted according to the needs, and the fertilizer formula is more flexible, which is suitable for the production of formula fertilizer. The nutrient content fluctuates greatly.
Compound fertilizer can only chemically synthesize several kinds of fertilizers in a certain proportion, and the ratio of nutrient distribution is relatively fixed and difficult to adjust. Suitable for the production of general fertilizers. The nutrient content is relatively stable.
Third, the particle hardness
Since the compound fertilizer is only granulated by the drum, the particle size is uniform and the hardness is generally small.
Due to the chemical synthesis, the compound fertilizer has a complicated production process and the hardness of the particles is generally large.
Fourth, the nutrient utilization rate is different
Due to the faster dissolution rate of compound fertilizer, once the nutrient is not absorbed by the crop in time, it is easy to be lost and the utilization rate is low.
Due to the slow dissolution rate of the compound fertilizer, the rate of nutrient release is also slow, and it is not easy to be lost. Therefore, the utilization rate is high.
Five, the price is different
The production cost of the compound fertilizer is low, as long as the various basic fertilizers are matched, and the mixture is stirred and uniformly granulated. Therefore, the price is relatively cheap.
Compound fertilizer production 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, so the price is relatively high.
