1. Definition

The quick solubility of high water-solubility potassium humate, decides its function to use for folia spray and drip irrigation with with promoted effect to release the locked phosphtae by some ions such as Fe3+,Al3+, also can  slow-release nitrogeon fertilizer to promote the function of NPK fertilizers.

2. Typical Analysis

3. Function& Benefits

1) Obvious effect to increase soil fertility and water holding capacity.

2) Improve the structure of soil; increase the buffering power of the soil.

In light, 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.

3) Neutralize both acidic and alkaline soil; regulate the pH-value of soil, with the prominent effect in alkaline and acidic soil.

Under alkaline conditions humic acid can buffer the pH can 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 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.

Salinalised soil: 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.

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) 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.

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

7) Stabilize nitrogen and improves nitrogen efficiency (ideal as an additive with urea).

 Complexes phosphate to reduce lock-ups (ideal as an additive with DAP/MAP, etc). 1). Obvious effect to increase soil fertility and water holding capacity.

4. Direction for use

Drip irrigation: 2-4kgs per hectareFoliar spray: 0.5-1kg per ha.Caution: please do not mix this product with acidic fertilizer, as it is not compatible with them.To produce 6% liquid solution, put 800g this humate into 10 liter of water at a very slow speed; agitate the solution at a constant speed. Please make sure the solution is even before transferring to the spray tank or irrigation tank.
