Characteristics of sodium humate
1. Look at the appearance of the product. Sodium humate for agriculture is dissolved in water, it is shiny granular or powder, slightly alkaline, rich in humic acid, polysaccharides, vitamins, minerals and other nutrients.
2. Determine the water-soluble treatment of sodium humate. The water solubility of humic acid fertilizer represents the production level of a manufacturer. The higher the water solubility, the better the performance of humic acid fertilizer in crops. Humic acid fertilizers without water-soluble treatment, of which humic acid is basically ineffective, except for alkaline soils.
3. Consult whether it can be used for plant auxins, does not contain any toxic and harmful substances, does not contain heavy metals, and will not cause any adverse effects on the soil and crops.
4. To determine the solubility, you can put a little sample into a water cup. The faster the dissolution rate, the less impurities in the product, the higher the purity, and the higher the fertilizer efficiency of the product.
5. Determine whether the soil moisture and water evaporation rate are stable and have a certain anti-early water retention effect.
