Leonardite Extract Humic Acid & Potassium Humate

Leonardite Extract Humic Acid & Potassium Humate 1. Product Definition   Potassium humate has prominent effect to fix and slow release nitrogen also release the phosphorous locked by Fe3+, Al3+ in the soil, meanwhile optimize micro element absorption and create a suitable environment for microbia, naturally work as additives for fertilizers, especially nitrogen fertilizer.   2.

  3. Function & Benefits 1) Largely increase the efficiency of fertilizers,especially Urea,ammonium sulfate,DAP,MAP.
2) Optimize the structure of soil to increase the buffering power and fertility of soil.
When the soil is less fertile also sandy to some extent ,humic acid will increase its cation exchange capacity to retain water and beneficial micro nutrient ,accordingly largely increase the fertility of soil.Under heavy and compact conditions,Humic acid will work with fungi to construct a crumb structure root to absorb water oxygen and nutrient also improve root penetration.
3) Neutralize both acidic and alkaline soil to release the beneficial metal ion,thus promote absorption by plants.
When the soil is alkaline, many beneficial meatal ion and other trace elements can not be absorbed by plants,humic acid can buffer the pH and convert the nutrients and trace elements into absorbable form and promote their uptake by the roots.
When in acidic soil, humic acid will tremendously reduce the toxins such as the ally aluminum and heavy metals, which will be bonded firmly and immobilized ,thus their toxicity is reduced and phosphate is bonded by aluminum is released.
Under Salinalised soil: Salts are split up by the high cation exchange capability, cation (eg.Ca, Mg) are bonded and chelated.
4) Promote plants growth also largely crease the yield and quality .
Humic acid stimulates the membrane of seeds to form a strong roots ,which is decisive to increase the capacity of root to take up both micro and macro nutrients .Based on improved structure by humic acid N is largely stored and slow released ,P is release from AL in soil,also other microelement is in the form of easy-available by plants,meanwhile the beneficial fungi is active to produce different kind enzymes.with the above joint effort,the yield will be increased at lease 30%. Enhanced cell assimilation as well as photosynthesis increase the plant’s sugar and vitamin content,thus the quality of their seeds will be largely increased.
5) Largely increase the plants’ ability to anti drought,frost under stressed conditions. Humic acid can mobilize K absorption to regulate the stomata open and close on the leaves also promote metabolism ,thus increase the plants’ ability under stressed conditions.
6) Detoxify the herbicide and pesticide residues.   4. Direction for use   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.
Irrgation:5-8kgs/ha/time
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. 5. Package 1) Woven bags with poly bags inside 25kgs net weight, 2) Jumbo bags with dischargeable open on the bottom,with poly bags inside. 3) Can satisfy the customer’s requirement     PRODUCTS SHOW           FACTORY SHOW       PACKING SHOW     LABORATORY SHOW       CERTIFICATE SHOW
