Why Is Humic Acid Fertilizer So Hot? After Reading It, You Will Understand!
Aug 07, 2018

Humic acid fertilizer uses peat, lignite and other raw materials, and uses different production methods to produce products containing a large amount of humic acid and nitrogen, phosphorus, potassium and some trace elements needed for crop growth and development. It is equivalent to an organic-inorganic compound fertilizer, which is a typical green environmental fertilizer, which can improve soil, increase effective nutrients, and stimulate crop growth.

Some people in the agricultural industry said that China's humic acid fertilizer production enterprises are small in scale, lack of funds, poor technical conditions, backward production process, high production cost and high energy consumption. The products produced are poor in appearance and unstable in quality, which seriously affects the application. effect. In addition, due to the lack of uniform standard implementation and testing standards, the products are mixed, which not only disturbs the fertilizer market, but also seriously affects the promotion and application of high-quality humic acid fertilizer.

However, with the development of ecological agriculture and the start of the “zero growth” of fertilizers, humic acid fertilizers will usher in development opportunities. At present, there are more than 1,000 humic acid fertilizer production enterprises in China, and it has become the world's largest producer of humic acid fertilizer.

According to the Ministry of Environmental Protection and the Ministry of Land and Resources announced the "National Soil Pollution Status Survey Bulletin" disclosed that soil pollution in some areas of China is heavier, and the quality of cultivated soil environment is worrying. Humic acid has an important role in improving soil and will usher in important development opportunities in the future. Let's let the farmer and wealthy take everyone to find out about it!

1. Synergistic effect on nitrogen fertilizer

Nitrogen fertilizer is mainly composed of carbonic acid and urea. The ammonium nitrogen is unstable in nature and highly volatile. After mixing with humic acid fertilizer, humic acid contains carboxyl, phenolic and other functional groups, and has strong ion exchange capacity and adsorption capacity. Reduce the loss of ammonium nitrogen.

Adding humic acid to urea has obvious synergistic effect on urea: first, the activity of urease is reduced, urea decomposition is slowed down, and volatilization is reduced; second, humic acid can form a complex with urea, and gradually release and release nitrogen. It is the prolongation of urea fertilizer efficiency, and the biological activity of humic acid can promote plant root development and nitrogen metabolism in the body, and promote nitrogen absorption.

2. Synergism effect on phosphate fertilizer

The quick-acting phosphate fertilizer is applied to the soil, and the soluble phosphorus is easily fixed by the soil. After the application of humic acid fertilizer, the soil can fix the water-soluble phosphorus, slow down the rapid-acting phosphorus to the delayed and inactive state, and the nitro-humic acid can increase the moving distance of phosphorus in the soil and promote the phosphorus to the root. Absorption.

3. Synergism effect on potassium fertilizer

Humic acid contains functional groups that can absorb and store potassium ions, preventing it from escaping with water in sandy soils and leaching soils, and preventing potassium fixation in sticky soils. Some parts of humic acid are low molecular humic acids such as fulvic acid, which have a dissolution effect on minerals such as potassium silicate and potassium feldspar, which can slowly decompose, increase the release of potassium, and increase the content of available potassium.

4. Synergism effect on micro-fertilizer

There is a considerable amount of trace element reserves in the soil, but there are too few effective parts that can be absorbed by plants. Humic acid and insoluble trace elements can undergo complexation reaction to form a humic acid trace element complex with good solubility and easy to be absorbed by plants, which is beneficial to root absorption or foliar absorption, and promotes the absorption of trace elements from plants by roots. Transfer to the ground part and spread from part of the blade to the other.

5. Indirect effects on the soil

Humic acid also improves soil structure and prevents soil cracking and soil erosion. In terms of physics, it can increase soil water holding capacity, improve its drought resistance, and at the same time darken the color of the soil, which is conducive to the absorption of solar energy. In terms of chemistry, it regulates the pH of the soil, improves and optimizes the plant's nutrition and moisture. The absorption, under alkaline conditions, acts as a natural chelating agent and metal ions to promote its root absorption.

In addition, humic acid can stimulate the growth and reproduction of beneficial microorganisms in the soil and improve the natural resistance of plants.
