Three main points of rational application of micro-fertilizer

Microelement fertilizer is the abbreviation of microelement fertilizer, which provides fertilizer with trace elements for plants, such as copper fertilizer, boron fertilizer, molybdenum fertilizer, manganese fertilizer, iron fertilizer and zinc fertilizer. They are mainly inorganic salts and oxides. Most of them are by-products or wastes of mining and metallurgy. They can be used to prepare multi-element foliar fertilizer for fruit trees, vegetable foliar fertilizer and compound fertilizer.

See crop application

Different crops need different amounts of micro-fertilizers, such as rice needs silicon; rape, leguminous crops need boron; garlic, onion needs selenium.

soil observation and fertilization

Different soils contain different types of trace elements. Only by knowing which element is lacking in the soil and applying the fertilizer with this element can it be effective. Such as boron deficiency, zinc deficiency, its boron content is less than 0.5 parts per million, zinc content is less than 1.5 parts per million, it is a lack of trace fertilizer. Before it is clear, it can be tested in small areas and then applied in large areas.

appropriate application of

Microelement fertilizer is generally used as base fertilizer. Apply boron 100~ 200g, zinc fertilizer 100~ 150g, ferrous sulfate 100~ 250g or copper sulfate 510g per mu, and avoid excessive application.
