1, How does humic acid "work" in soil?

The hydroxyl and carboxyl groups in humic acid easily polymerize with the calcium ions in the soil, and form the aggregate structure of the soil through the physiological action of plant roots. When the aggregate structure of the soil becomes better, the seven bulk density will decrease and the porosity will increase, so that it will have good permeability. Humic acid is also an important cementing agent for the formation of soil aggregate structure. The formation of soil aggregate structure improves the soil organic and inorganic composite degree, increases the number of water-stable large particle aggregates, and improves the soil structure. Therefore, humic acid can improve the physical properties of the soil. By applying various organic materials, amendments, water-retaining agents, and degradable liquid mulch film, the share of humic acid in the soil can be increased. Studies have shown that the application of humic acid materials on desertified land can increase the content of water-stable microaggregates larger than 0.25mm in the soil by 32%-72% compared to the control. A variety of organic materials have been used to awaken and kill the soil to improve fertility. The research results show that the use of peat and wheat straw can reduce the content of soil sand and silt particles, and the clay particles smaller than 0.001mm and those smaller than 0.01mm The physical clay content is just the opposite. Obviously, compared with other organic materials, humic acid has certain advantages in improving soil physical properties. The application of humic acid materials can promote the development of crop roots and make crops form huge deep roots, which is beneficial to the regulation of water, fertilizer, gas, and heat conditions in the soil, and helps crops absorb water and nutrients. At the same time, the effects of humic acid fertilizer in retaining water and fertilizer are beneficial to the growth and development of crops. In turn, increase crop yields.

2, Direction for Use of humic acid water soluble

a>Foliar spray: 0.5-1.0kgs/1000kgs Water, Spray the plant till the leaves are wet each time,at least 3 times during crop cycle;

b>Root Flushing/Irrigation/Fertigation:2.0kgs/1000kgs Water, 120-150kgs/acre apply alone or stir well with normal NPK and apply the solution before seeding or between the plant growing, at least 3 times during crop cycle;

c>Seeds Soaking: 2kgs for 1000kgs seeds.

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.


1) Improve the structure of soil; increase the buffering power of soil. Optimize N,P,K absorption by plants.

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

3) Stimulate plant growth, increase the yield and quality.

4) Reduce nitrate leaking into the groundwater and protect the underground water

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

6) Stabilize nitrogen and improve nitrogen efficiency (ideal as an additive with urea). Complexes phosphate to reduce lock-ups (ideal as an additive with DAP/ MAP, etc).
