Potassium humate is a kind of efficient organic potassium fertilizer,it’s water soluble product,it’s the most abundant and the most common organic compound type in the nature.And potassium humate is widely used in agriculture,oil drilling,chemicals, construction material,pharmaceuticals industry.etc.It’s environmental friendly,now is popular used all over of the world. The humic acid is a kind of biological activity agent which could improve soil active potassium content and reduce potassic loss and fixation.It has the functions of improving the NPK efficiency.
Function
1. Promote the absorption of potassium by crops,enhanced the root development,improve crop antibodies,reduce potassium shortage phenomenon.
2. Stimulate cell division,improve the environment of plants,develop deep roots and luxuriant leaves,increase the crops yield.
3. Improve soil structure,promoting crop growth,enhancing crop’s resistant ability to adverse environment conditions,improve crop quality and protecting agro-ecological environment.
4. Stimulate plant growth increase the yield and quality.
Stimulate the membrane of seeds as well as the metabolic activities and thereby increase the germination rate. Increase the capacity of root to take up nutrients (N, P, K + Fe, Zn and other trace elements) as these elements is easier to be converted into forms available to plants. Accordingly, the yield will be increased up to 30%.Enhanced cell assimilation as well as photosynthesis increase the plant's sugar and vitamin content.
5. Increase the effectiveness of herbicide pesticide and fungicide, immobilize or reduce their harmful residues.
Vegetables:
150kg-225kg/hectare for drip irrigation and fertigation.
