How to add micro-fertilizer to soybeans?

How to supplement microelement fertilizer to soybean? Please give an introduction Soybean needs some trace elements for normal growth, among which molybdenum, boron, zinc and manganese are more important. Molybdenum is a component of soybean nodule nitrogenase and an indispensable component of normal life activities of nitrogen-fixing bacteria. Boron is also very important in soybean life activities, lack of shed soybean root development is not good, nodule growth is not good, lose nitrogen fixation ability. Therefore, attention must also be paid to trace elements. The abundance and deficiency of trace elements in soil and environmental conditions determine whether trace elements needed by soybean can be satisfied from soil. For example, low-lying or poorly drained soils are most likely to lack manganese, iron in calcareous soils, and molybdenum in acidic soils with pH below 6. In the application of microelement fertilizer, it is better to apply seed coating when sowing, which is more economical. If trace element deficiency is found at seedling stage, foliar topdressing should be adopted, spraying with 0.1% molybdic acid solution before flowering of soybean, spraying 40-50 kg solution per 667 square meters.
