Potassium humate benefits farming

Potassium humate benefits agricultural farming

How Potassium humate benefits agricultural farming?Firstly,In the soil where humic acid forms agglomerate structure, the activity of microorganisms is strong, the biological activity is high, the nutrient supply is sufficient, and the preservation and supply of soil nutrients can be well coordinated, thereby improving soil fertility:
After the soil microorganisms are multiplied, the effective nutrients that are solidified by the soil are converted and released, thereby improving the utilization rate of the fertilizer.

Improve fertilizer efficiency: inhibition, complexation, release, absorption

In terms of nitrogen fertilizer, humic acid has an inhibitory effect on urea-decomposing enzymes and nitrate-degrading enzymes in soil. “The compound fertilizer and compound fertilizer mainly use urea as nitrogen fertilizer, and urea is amide nitrogen.

After being applied to the soil, it must be converted into ammonium nitrogen or nitrate nitrogen by urease to be absorbed and utilized by crops. Urease has an inhibitory effect on nitrifying enzymes, thereby increasing the utilization of amide nitrogen.”

The inhibitory effect of humic acid on the enzyme can last for about 100 days. In the growing season of the crop, humic acid can inhibit the decomposition of urea, thereby reducing the volatilization of urea. This proves that humic acid has a sustained release effect. In the middle and late stages of crop growth, as the crops absorb humic acid, their inhibitory effect on urease is weakened, and the urea release is gradually increased to meet the large demand for nitrogen in the period of vigorous crop development. In addition, humic acid can inhibit the activity of nitrifying enzymes, increase the utilization of urea, and increase the stability of ammonia.

The direct cause of humic acid to improve the efficiency of phosphate fertilizer is that humic acid forms a complex of humic acid-metal-phosphate with phosphorus fertilizer, such as humic acid iron, aluminum humate, and humic acid phosphorus, thus forming a complex.

It can prevent the fixation of phosphorus in the soil, and can make the crop easy to absorb, thereby increasing the utilization rate of phosphate fertilizer, and the utilization rate is increased from 10%-20% to 28%-39%.

In the soil, the phosphate fertilizer is generally monoammonium phosphate and diammonium phosphate, which are easily fixed in the soil, so the utilization rate is low. After the addition of humic acid, a ternary stable structure is formed to make phosphorus, iron, calcium, magnesium, Aluminum or the like forms a ternary complex or chelate compound, thereby increasing the utilization of phosphorus.

In terms of potash, potassium humate can promote the release of poorly soluble potassium, increase the release of available potassium, especially water-soluble potassium, and also reduce the fixation of potassium.

When humic acid is combined with potassium ions, the part of the potassium that is solidified in the soil is released, and can be absorbed and utilized by the crop, which can be absorbed and utilized by the crop, thereby greatly improving the utilization of potassium and reducing potassium. Loss with water and is fixed by the soil.

Because potassium humate has a large number of reactive groups (carboxyl, phenylhydroxyl, methoxy) complexing with trace elements in the soil, the part that is solidified by the soil cannot be absorbed and utilized by the crop to be absorbed. Therefore, greatly improving the utilization of trace elements. ”

Enhance resistance: crops are “strong and strong”, high quality and high yield

Potassium humate has an immediate effect on enhancing crop resistance, which is equivalent to the auxiliary crop becoming “strong and strong”, while making the crop high-yield and high quality. How to do it?

First, it promotes crop breathing

When potassium humate or humic acid is applied, it can be expressed on the crop: the root system is developed and the secondary roots are increased. Test data show that ammonium humate can increase the respiration intensity of rice by 18.2% and light and intensity by 12.2%.

Second, is to promote the activity of the enzyme

One is to promote enzyme activity in the soil, and the other is to promote the activity of the plant itself, increasing by 24.4%-175.6%. After the application of potassium humate to different crops, the activity of the enzyme was increased differently. Taking wheat as an example, the application of potassium humate can increase the enzyme activity of wheat by 62%-82%, and promote the growth, respiration and photosynthesis of wheat. When the crop is in premature aging or water shortage, the nitrate reductase in the plant will decrease. A set of experimental data on wheat indicates that potassium humate is applied at the booting stage and filling stage.
After that, the decay rate of nitrate reductase can be reduced from 37% to 21%, which makes wheat drought-resistant and avoids premature aging.

Third, is to promote nutrient absorption

Potassium humate can complex or chelate with trace elements, increase the solubility of trace elements, and transport them to plant-related tissues through cell absorption. At the same time, humic acid has a better affinity with roots and crop surfaces, and it is easy to absorb nutrients into plants. According to the test, after the application of humic acid, the absorption of phosphorus by crops can be increased by 7%-30%, and the absorption of nitrogen by 4%-15%.

Fourth, it is to promote early germination and increase the emergence rate

After seed dressing with potassium humate, taking wheat as an example, the emergence rate can be increased by 10%-30%, and emergence in 1-3 days. In rice, the seedling rate can be increased by 27% – 38%. In addition, the seedling rate can be increased by 10%-30% for different crops.

Fifth, it is to promote the development of root system

Under normal circumstances, the application of humic acid and potassium humate can increase the root system by about 30%, which can increase the crop tillering rate, root coefficient and length. Seed dressing with potassium humate, the number of wheat roots during wintering increased by 27.9%, the length of secondary roots increased by 43.96%, the number of tillers per plant increased by 18.18, the number of wheat roots increased by 13.24%, and the length of secondary roots increased by 28%. The number of tillers per plant increased by 11.63%.

In terms of improving crop stress resistance, it is obviously characterized by drought resistance, cold resistance, high temperature resistance, pest and disease resistance, improvement of agricultural product quality and improvement of crop yield.
