Micronutrient fertilizer, namely trace elements fertilizer, including zinc sulfate, ferrous sulfate, manganese sulfate, boron fertilizer and so on . How to use it well? Rech Chemical Changsha teach you three skills to well use micronutrient fertilizer.
1,check the soil before fertilization
Different soil contains different trace elements. Only by knowing which elements the soil lacks, we can choose the effective solution to make up. At present, according to soil organic, quality and PH value, we make sure the soil contents. If Lacks boron or zinc,its boron concentration will be less than half point of one millions and its zinc will less than 1.5 of one million. Then it could be called micronutrient deficiency. You’d better do some experiment in small area before widespread use , or it will be worse without knowing which lacks.
Second,check the crops before fertilization
Different crops have different requirements of micronutrient fertilizer, such as rice need silicon; Rape, leguminous crops need boron, while Garlic and onion need selenium.
Third, control the fertilizer’s dosage
Micronutrient fertilizer is usually applied as base fertilizer. Fertilize boron 100~200g per area, or zinc sulfate 100~150g, or ferrous sulfate 100~250g or copper sulfate 510g. Do not fertilize too much.
