Humic acid Potassium Salt (Potassium humate) (K-humate) NPK fertilizer is one of the major components of humic substances. Humic acid Potassium Salt (Potassium humate) (K-humate) is obtained by alkaline extraction of lignite or brown coal or leonardite and is used commercially as a soil conditioner.
Chemically, it is a super-molecular heterogeneous aromatic hydroxy carboxylic acid composed by various functional groups, taking on effects of sorption, complexation, chelation, flocculation, which dissolves loads of hydrophobic matters.
Function & Benefits:
Enhancing nutrient uptake by combining nutrients and humic aid as well as keep a well-balanced nutrition.
Improving the structure of soil, increasing the buffering powder of soil, optimize N. P. K absorption by plants.
Neutralizing both acid and alkaline soils, regulating PH value of soils with prominent effect in alkaline and acidic soil
Reducing nitrate leaking into the groundwater and protect the underground water
Enhancing the resilience of crops, such as cold, drought, pest, disease and toppling resistance
Stabilizing nitrogen and improving nitrogen efficiency (as an additive with urea)
Promoting healthier, stronger plants and beautifying appearance
5-10kgs/ha/time, 2-3 times during seedling and growth stage, better to be applied with N, P fertilizers
Mixed with Nitrogen fertilizers: 5% of total blend i,e, 5kgs of Potassium Humate per 100kgs of Urea
Used as muti-functional compound and basal fertilizer, top dressing, seed fertilizer and foliar fertilizer
