The functions of humic acid compound fertilizer in improving crops and their growth environment are mainly as follows: (1) Improve soil, adjust soil salinity, and increase soil aggregate structure, especially for improving saline-alkali land. (2) It has obvious nitrogen fixation, phosphorus dissolution and potassium slow release. It reduces nitrogen volatilization loss, converts phosphorus in soil […]
Fulvic acid compound fertilizer is a new achievement of the world fertilizer industry research. It has stood at the forefront of the development of the fertilizer industry. It is the main direction for achieving high-yield, high-quality and high-efficiency agricultural services. Characteristics of fulvic acid compound fertilizer Basic composition of fulvic acid compound fertilizer Fulvic acid
Common potassium humate on the market is generally divided into two types – mineral potassium humate and biochemical potassium humate. There are many differences between these two types of potassium humate. Different sources Mineral humic acid is extracted from minerals such as weathered coal and peat, while biochemical humic acid is extracted from food residues,
As mentioned above, humic acid substances have the effects of solubilizing, enhancing efficacy and reducing the decomposition rate of pesticides. What kind of impact will these effects have on the toxicity of pesticides after use? This is a question that everyone is concerned about. With this question, Jingfeng Humic Acid researchers studied the acute combined
Researchers studied the degradation effect of humic acid on organophosphorus pesticides. In the research example, the decomposition rate of methyl parathion mixed with humic acid in a ratio of 10:3 and methyl parathion without humic acid was compared with that of methyl parathion after 15 days at 40°C. The decomposition rates of pesticides after 30
Research on the synergistic effect of humic acid on pesticides, reported in the literature alone, is sufficient to illustrate the significant effects achieved by the combined use of humic acid and pesticides, including pesticides, fungicides, herbicides and plant growth regulators. Specific examples mainly include the use of humic acid in combination with copper or gram
Humic acid solubilization effect on pesticides Humic acid has been widely used as a surfactant in many industries at home and abroad. It is reported that the surface tension of alkali metal salts of peat humic acid and weathered coal humic acid is lower than the surface tension of water to varying degrees, and the
The study of the mechanism of action between pesticides and humic acid has shown that the results obtained from different angles and using different technical means are not quite the same, but all indicate that humic acid has a high potential adsorption capacity for pesticides. The specific research conclusions are: (1) There are ionic bonds
In order to fully exert the effect of humic acid fertilizer after application, pay attention to the following humic acid fertilizer usage and taboos when using it: ① The pH value of potassium humate and sodium humate liquid fertilizer spraying is best controlled at 7.2-7.5. If it exceeds 8, add a small amount of acid
Humic acid is a substance necessary for plant growth. We can prove in practice that plants need humic acid. (1) Some deforestation pioneers often give up planting crops in one place after 1-2 years. The reason is that after planting crops, the organic matter in the soil is consumed in large quantities. If it is
