Soil problems have caught everyone’s attention. The State Council issued a notice on the action plan for soil pollution prevention and control, as well as a draft law on soil control, which has been submitted to the National People’s Congress for approval. All of this shows that the country has begun to pay great attention to the protection and treatment of soil pollution. How to achieve such a great goal, such as
How to repair soil pollution? The key issue is to change the traditional way of thinking. To balance thinking, the key is to reduce fertilizer. However, the core of reducing fertilizer is not to use chemical fertilizer.

Humic acid plays an irreplaceable role.

Humic acid is the essence of soil organic matter and is the most effective organic matter. The effect of humic acid on the soil is firstly to increase the soil aggregate diameter and thus the soil porosity. Secondly, humic acid contributes to the controlled release of elements such as NPK through the combination with organic matter. There are also various organic pollutants such as complex heavy metals and pesticide residues, which reduce the pollution degree of soil organic and inorganic pollutants. Third, the amount of microorganisms in the soil can be increased. Humic acid can promote the growth of microorganisms and change various enzymes in the soil, thereby increasing the carbon and nitrogen cycle in the soil.

Among the new types of fertilizers, mineral humic acid fertilizer and ore source fulvic acid fertilizer are very important. In the past, many microbial-rich fertilizers could not be directly mixed with chemical fertilizers, which inhibited the activity of microorganisms and even killed microorganisms. This problem is solved if humic acid is used as the medium. Because humic acid is organic. Therefore, the combination of mineral source humic acid fertilizer and other organic and inorganic fertilizers is relatively safe, and the effect is also 1+1>2.

Largely promote the buffering power and fertility of soil by improving the structure.
In sandy soil, humic acid will help to increase fertility of soil through its cation exchange capacity to retain water and beneficial micro nutrient .In heavy and compact soil ,Humic acid will work with fungi to construct a crumb structure root to absorb water oxygen and nutrient also improve root penetration.

Neutralize both acidic and alkaline soil to release the beneficial metal ions, thus promote absorption by plants.

In alkaline soil, beneficial 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.
In acidic soil, humic acid will largely 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.
In salinalised soil, Salts are split up by the high cation exchange capability, cation (eg.Ca, Mg) are bonded and chelated.

Largely optimized the absorption of beneficial ion by plants thus increase plants growth accordingly increase the yield and fruits 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.

Enhance plants’ ability to counter 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.

Natural nitrogen stabilizer.in Soil if these sufficient humic substance there will be at least 35% of soluble nitrogen applied and held in the soil in the form of organic ,then convert into stable form ,finally bioavailable form.

Strong ability to release the lock up Phosphorus in soil,as humic substance has stronger CEC that will greatly chelate the cation from phosphate and release anion phosphate radicals.

How to ues these humic acid?

It is advised to use humic acid to mix with other chemicals ,or compost,manure fermentation,also additives to pesticide.
