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

Physiologically, the effects and functions of humic acid on plants (1) Strengthening respiration Some people call humic acid “respiratory fertilizer”. It is generally believed that because humic acid molecules contain phenols and quinones, which can be converted into each other, it can be both a hydrogen carrier and an oxygen activator, forming a redox system

Effects and functions of humic acid on plants 1. Improve the drought and flood resistance of plants Because humic acid has such functions: it can reduce transpiration of plants, so it is resistant to wilting. It has a redox system, which promotes the respiratory function of plants, making them more resistant to the difficulty of

Effects and functions of humic acid on plants 1. Promote root germination and growth Humic acid promotes the germination and growth of plant roots, which is the most impressive. But people may say that good root growth does not necessarily mean high yield. This is also true. Under ideal cultivation conditions, they may all grow

3. Waterweed basal fertilizer The waterweeds planted in the waterweed tank have different leaf colors and a wide variety, but usually the cut waterweeds are planted in a sand bed containing nutrient basal fertilizer. In order to make the waterweed grow new roots faster to absorb nutrients, sodium humate is used to stimulate plant rooting
