Manufacture of Potassium Humate(Humic acid) Liquid 2-4%

It is well-established fact that the humus in soil serves to stimulate the plant growth. Humic substances are arising from chemical and biological degradation of plant and animal residues. This product alone is not a nutrient. It absorbs nutrients and water and releases slowly. Depending on the crops, dosage is fixed as soil application or as foliar application after suitable dilution. Humic acid or salts of humic acid have been shown to increase the availability and uptake of nitrogen, phosphorus, calcium, iron, and magnesium; increase the osmotic process; provide release of auxins and amino acids; and serves as quality substrate for microorganisms. Humic acid is found naturally in soils, but does not exist in all soils in quantities that will support optimal crop and tree growth. Adding potassium humate rich in humic acid to the soil is a positive, natural practice and promotes long term health of the soil. Potassium humate can be mixed with organic manures and fertilizers, applied as seed soaking treatment, root application, foliar application or used directly during fertigation. Neyveli Lignite is rich in humic substance. This patented process (Indian Patent No: 201577) invention provides an efficient method for extraction of humic acid in the form of potassium humate from lignite as raw material.

Sector: Agriculture & Agro-industry
Country: India
Area of Application:
Applications: In Agriculture: In general, potassium humate stimulates the growth. The quinoidine and active acids within the product bear strong potentiality of oxidation, which restrains the activities of free radicals and hence, avails the development of the foliage and positively influences plants metabolism, photosynthesis, respiration, activity of ferments. Potassium, acting on the cell level, facilitates the absorption of nutrients by the roots and the exchange of gases through the stomata; this element is also a vital constituent of chlorophyll, speeding up photosynthesis. Potassium Humate alleviates the toxicity of pesticide residue and prevents soil from contamination of heavy metallic ions as well as other harmful matters. It has good cation exchange property. This improving the utilization of fertilizers, it, combining with such elements as N, P and K, constitutes highly-efficient multi-function compound fertilizers. Application of potassium humate results in higher yields and better product quality, more massive root system, positive ecological effects, increased soil tolerance to drought. It is highly suitable for all types of crops application, and ideal for fertigation.
Keywords: Humic acid, potassium humate ,organic Nutrient ,soil replenisher
Advantages:
Potassium humate is obtained by alkaline extraction of lignite by indirect heating method. Potassium humate is a polymeric heterogeneous aromatic and aliphatic hydroxyl carboxylic acid salt. It is comprised of active groups such as hydroxyl and carboxylic. A dark brown solution (2-4% conc.) easily soluble in water and is slightly alkaline in property.
