Agricultural use of Potassium humate

Agricultural use of Potassium humate

Potassium humate uses in agriculture raises soil, keeps fertilizer, and the quality of crops naturally grown is good. However, with the continuous advancement of fertilizer technology, farmers are increasingly demanding the water solubility of humic acid products. Ammonium humate is difficult to dissolve, sodium humate contains sodium, and it is restricted under certain conditions.

Potassium humate is well-dissolved and has no side effects on plants and soil. It is the most suitable raw material for making compound fertilizer and water-soluble fertilizer. With the advent of potassium humate, the era of large-scale agricultural use of humic acid has arrived.

1 Humic acid potassium into a breakthrough in innovation At the beginning of the last century, Germany began artificial production of ammonium humate, and the Soviet Union began mass production of humic acid products. After World War II, Japan began to produce nitro humic acid for soil improvement.

In the middle and late last century, the United States began to appear potassium humate liquid fertilizer extracted from lignite, and sold in many parts of the world. China’s humic acid resources are very rich, and it has become a major producer of humic acid potassium. However, in the field of compound fertilizers and water-soluble, potassium humate has not been applied on a large scale.

At present, many fertilizer companies are involved in the production of humic acid fertilizer and Agricultural use of Potassium humate. Beijing Carbon Source Power Agriculture Development Co., Ltd. adheres to the principle of good fertilizer for the benefit of Chinese farmers, and fully develops the source of potassium humate and fertilizer, and sublimates the simple fertilization into soil improvement behavior. .

2 The comprehensive demonstration effect is obviously based on the results of the announcement of the fertilizer registration certificate of the Ministry of Agriculture. Up to now, there are 4,636 registered products of potassium in China, of which 1,527 are humic acid fertilizers containing potassium, accounting for about 1/3.

According to the results of the “National Intellectual Property Office” potash patent search, from 1988 to 2015, there were 296 patents for potash fertilizer, including 28 patents of potassium humate/potassium fulvic acid (2007-2015 only), accounting for 14.1 of the potash fertilizer patent for the same period. % (2,164 patents for humic acid fertilizers in 1985-2014).
For more than 30 years, a large number of experimental studies have proved that potassium humate can improve soil available potassium content, increase potassium absorption and utilization, promote crop yield increase, improve crop quality, enhance crop resistance, etc., and achieve good results in agricultural applications.

To this end, Zeng Xiancheng, chairman of the China Humic Acid Industry Association, said that the comprehensive test of potassium humate was obvious and attracted many experts in the industry to study. The first is to increase the soil available potassium content.

The results showed that potassium humate could reduce the absorption and fixation of potassium in soil and increase the content of available potassium in soil. The soil available potassium content increased by 42.5%, and the potassium recovery rate increased by 81%. The second is to increase the utilization rate of potassium fertilizer.

Wang Zhenzhen, from the Agricultural College of Shandong Agricultural University (2012), studied the effects of humic acid slow-release potassium fertilizer on soil potassium content and sweet potato absorption and utilization.

The results showed that the application of humic acid promoted the absorption of potassium by sweet potato and increased the content of available potassium in the middle and late stages of sweet potato growth. The third is to promote crop yield increase.

The results showed that when the ratio of urea to potassium fulvic acid was 200:1, the yield traits and yield of corn were the best compared with the control treatment, the yield was 9075kg/hm2, and the yield was 19.56%. The fourth is to enhance the ability of crops to resist stress. The fifth is to improve the quality of agricultural products.

Applications will tend to be personalized from the soil solid phase composition, in addition to minerals, is the soil organic matter. Humus is the main constituent of soil organic matter, accounting for up to 80%; humic acid is the most active component of humus, accounting for more than 75%.

Throughout the intimate relationship between “humic acid – humus – organic matter – soil”, we can easily find that humic acid is the fundamental property of the soil.

The combination of humic acid and potassium through organic-inorganic phase not only can bring potassium into harmony, but also improve the utilization efficiency of potassium, and realize the supply of potassium fertilizer in the same lineage of soil. The special fertilizer of potassium humate is effective in improving the quality, and its individualized application is more and more extensive.

At present, the coverage area of ​​special fertilizer for humic acid shows a clear upward trend. Potassium humate potassium special fertilizer can increase rice yield, promote rice filling, make it full of granules and improve rice quality; potassium humate potassium special fertilizer can increase wheat grain yield and protein content, effectively increase wheat yield and improve wheat Quality;

potassium humate potassium special fertilizer can improve the disease resistance of corn, increase roots, strengthen stalks, increase corn seed setting rate and 1000-grain weight; humate phytate and soybean special fertilizer can significantly increase soybean yield and enhance crop disease resistance, and Soybeans mature early.

Potassium humic acid can be used in soil fertilizers. In the case of soil, humic acid is potassium in potassium; in the individualized application of products, the role of the target is more and more obvious; in terms of quality and efficiency, the quantification is more and more accurate. Potassium humate and potassium humate are not only stable, but the growth trend will be stronger.

At present, in the face of the rigid growth of food demand, in the face of the strong promotion of “Zero Fertilizer Zero Growth Action”, in the face of the high-grade requirements of the “tongue” of ordinary people, the production plant of humic acid potassium and humic acid potassium fertilizer will become the “fire line” family, “ Firepower will be more and more prosperous.
