What kind of fertilizer is coated compound fertilizer
Coated compound fertilizer is a plant nutrient complex formed by one or more plant nutrients wrapping another plant nutrients. Its principle is similar to "Yuanxiao", with stuffing (core), skin, layers of packaging, so that fertilizer package, a variety of fertilizers as one. The coated compound fertilizer is different from the ordinary compound fertilizer in five aspects. First, the granulation process of the coated compound fertilizer is different. The ordinary compound fertilizer is granulated by the mixture of several kinds of fertilizers or directly mixed (such as BB fertilizer). Coated compound fertilizer is made of fertilizer wrapped in fertilizer and wrapped layer by layer. Second, after applying to the soil, the rate of deep solution and release are not the same. The common compound fertilizer dissolves quickly and releases quickly, while the coated compound fertilizer dissolves slowly and releases slowly. Third, the utilization rate of fertilizer is different. The release of ordinary compound fertilizer is fast, the fertilizer efficiency is short, and the fertilizer use efficiency is generally 30% to 40%. The coated compound fertilizer has the advantages of slow release and long fertilizer efficiency, and the fertilizer use efficiency is generally between 50% and 70%. It is 20 to 30 percentage points higher than the former. Fourth, the fertilizer supply capacity of crops is different. The fertilizer effect of common compound fertilizer is short, and it must be topdressing many times in order to meet the nutrient needs of plant growth and development. The fertilizer effect of coated compound fertilizer is long-lasting, and a full amount of basal application can basically meet the nutrient needs of crop growth and development. Fifth, the residue is different, the common compound fertilizer is completely soluble or basically soluble, the residue is less, and the stamina is small. The coated compound fertilizer dissolves the core and the residual empty shell.
