钾humate植物生长调节

Potassium humate 55% 65% 75% content crystal and granule we are professional humate supplier in China Function: 1) Promoting the formation of good soil structure,increasing the cation exchange capacity (CEC), water-holding capacity, and the capacity of fertilizer retention. 2) Promoting nutrient uptake by plants and enhances the soil's ability to chelate nutrients and to promote exchange of nutrients between plants and the fertilizers being applied. Thereby reducing the loss of applied fertilizers from leaching and run off. Because they are already a part of a certain organic structure, the humates' chelate complexes with microelements can penetrate into the cell more easily than ordinary ions. 3) Stimulating beneficial microbial activity and root growth. Long-term research showed that humic substances bond many organic and non-organic substances into poorly soluble or insoluble compounds, so it reduces the toxic effect of residual amounts of herbicides, soil polluting radio nuclides, heavy metals, and other harmful substances, as well as radiation and chemical contamination. 4) Improve crop stress-resistance ability, it has been proved that the humates help to fight the effect of droughts and ensures their drought resistance. Long-term experience in the use of humates in China has shown that their presence is important during all stages of plants'development but particularly vital in the early stages. The pre-planting treatment of seeds is very important. Even before germination begins, vital forces are awakened, and the immune system is stimulated. 5) Increase the yield and quality of various crops. Humates contain more biologically active components, and it directly affects their use. Packing: is available in 25kg/bag.
