Microelement fertilizers are mainly inorganic salts or oxides. Some minerals and metallurgical by-products or waste materials can often be used as raw materials for microelement fertilizers. The production method is the same as that of inorganic chemical products.
Due to the small amount of application per unit area, it must be diluted with a large amount of inert substances before application. Uneven application will poison some crops. Microelement fertilizers often need to be mixed into macro fertilizers and applied together, usually in two ways: one is to mix them in the production of macro granular fertilizers. This method is more convenient and economical, and does not produce uneven nutrients. The disadvantage is that it is less flexible and difficult to meet the various requirements of the market; the other is to coat the surface of the macro-granular fertilizer with the trace element fertilizer powder. This kind of operation can be carried out in the secondary processing plant, which can meet the needs of the market at any time.
There are two ways to apply trace element fertilizers: soil application and foliar spraying.
Soil fertilization: In addition to chemical fertilizers (such as borax, zinc sulfate, manganese sulfate, etc.), the commonly used micro-fertilizers also include glass fertilizer, slag or scraps, which are usually used as base fertilizer or seed fertilizer. The application method is as follows: before sowing, combine with soil preparation and apply it into the soil, or mix it with nitrogen, phosphorus, potassium and other chemical fertilizers, and apply it uniformly. The application amount should be determined according to the types of crops and micro-fertilizers, and generally should not be too large.
Extra-root topdressing: mix soluble micro-fertilizer into a certain concentration of aqueous solution, and spray the crop stems and leaves. The advantage of this method is to avoid the harm caused by uneven fertilizer in the soil, and it can also be sprayed multiple times according to specific needs at different development stages of the crop to improve fertilizer efficiency.
