Humic Acid

Humic Acid

Humic acid is a powder ,flakes or granular from Leonardite.,leonardite humic acid potassium salt /humic plus. It is a basic raw material for manufacturers in agricultural and natural additive for fertilizer to improve the structure of the soil and increase the fertility.

Functions & Benefit:

Humic acid water soluble improve the structure of soil; increase the buffering power of soil.
In light and sandy soils, humic acid increase the cation exchange capability to retain nutrients and water, importantly to magnify the ability of root to take up nutrients. In heavy and compact soils, working with fungi to create a crumb structure for better water oxygen and nutrients intake and improved root penetration.

Organic fertilizer humic acid can neutralize both acidic and alkaline soil; regulate the pH-value of soil.
Under alkaline conditions, humic acid can buffer the pH and convert the nutrients and trace elements into absorbable form and promote their uptake by the roots, as under high pH value many essential nutrients and trace element are not in plant-available form.
In acidic soil, it can largely reduce the toxins such as the ally aluminum and heavy metals, which will be bonded firmly and immobilized by humic acid, thus their toxicity is reduced and phosphate is bonded by aluminum is released.
Lowes lawn fertilizer humic acid granule for salinalised oil: Salts are split up by the high cation exchange capability cation (eg.Ca, Mg) are bonded and chelated. The high osmotic pressure within the root area is largely reduced.

Humic acid powder 95% 85% 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.

Humic and fulvic acid benefits reduce nitrate leaking into the groundwater and protect the underground water.
Humic acid binds the nitrate and keep it around the root zone, in this way drinking water is better preserved.

Increase the effectiveness of herbicide pesticide and fungicide, immobilize or reduce their harmful residues.

Direction for use:

KHUMIC-100 (humic plus/humic acid 95, humic acid98) application:

Base fertilizer:

5-10kgs/ ha, better to be applied with N, P fertilizers Mixed with Nitrogen fertilizer: 5% of total blend ie.
5kgs of potassium humate per 100kgs of Urea.
Also it depends on the soil condition.
Caution: Dissolve the material in a small tank and do filtering when used for drip irrigation tank, The residues can be used as
base fertilizer.

Humic acid granule application:

Agriculture and Forestry: Organic Fertilizer, used alone in Turfgrass; Compound with other fertilizers to produce N.P.K fertilizer, raw material of plant nutrition liquid; Agents of pesticides, soil, and stockbreeding, etc.

Turfgrass Application: Greens: 750-1000 kg / ha annually Tees & Fairways: 500-1000 kg / ha annually


Woven bags with lining 25kgs net weight, also can satisfy the customer's requirement.
