Potassium humate has important uses in agriculture. Fulvic acid, black humic acid and brown humic acid are collectively called humic acid. In which fulvic acid has the unique effects of small molecular weight. High active gene. Improving soil . Promoting soil temperature. Enhancing root development. Effectively regulating soil acidity and alkalinity, solving soil consolidation and so on. In the case of dry climate, reduce the stomatal opening of crops. Commonly known as drought resistance No.1.Potassium fulvate, used in combination with other inorganic fertilizers (such as nitrogen, phosphorus, potassium, etc.). Can fix nitrogen, hydrolyze phosphorus. Release potassium slowly. Promote the transformation of active components. Be absorbed and utilized by crops as soon as possible. And increase the utilization rate of all kinds of active components upto 80%. And the potassium humate has many uses in agriculture.
The application of potassium fulvate in vegetables
The potassium humate mainly to prevent vegetable soil pollution and stubble pathogen infection. To effectively destroy the propagation of soil germs. To enhance soil aggregate structure. Effectively promote crops to root more. To grow new roots. To promote root development. To improve plant disease resistance. To stimulate vegetable growth, to enhance crop photosynthesis. To make vegetables grow vigorously, to increase yield per unit area. And to increase vegetable farmers’ income.
Effect and application of potassium fulvate on Fruit trees
The application of potassium fulvate in fruit trees can promote the development of root system. Improve the utilization rate of fertilizer. Increase the fruit setting rate. Enhance the color of fresh fruit, Improve the quality of fruit, tolerate storage after harvest. Prevent root rot. And have a good conditioning effect on the diseased and diseased branches of fruit trees. There is a peach tree in the orchard, the whole dry dead leaf. There is a persimmon tree a dry branch dead leaf, with potassium fulvate fertilizer root irrigation, peach trees, persimmon trees spit new buds. Thus the fruit farmers call it the divine effect of coming back from the dead.
Potassiumfulvate is also widely used in cotton, corn, wheat, melon and fruit crops. And the effect is also more obvious than that of inorganic fertilizer. To sum up, potassium fulvate has the special effects of drought resistance and soil moisture preservation, loose soil, increasing ground temperature, improving soil acidity and alkalinity, stimulating crop growth and so on. It has attracted the attention of related agricultural systems.experts in the agricultural sector. It is listed as the green fertilizer source of organic matter, and is welcomed by the majority of farmers.
The properties of potassium fulvate and the basic function of preventing and treating cotton fusarium wilt
And the potassium fulvate is a high-molecular organic compound with a lower molecular weight of the humic acid. It contains various active functional groups, can be dissolved in water, acid, alkali, ethanol and acetone. Easy to be absorbed by plants, has strong biological activity. And is widely used in agricultural production. It not only can supply sufficient nutrient components of the cotton, but also can adjust the physiological function of the cotton. So that the cotton can enhance the stress resistance and effectively inhibit the occurrence of the cotton fusarium wilt.
Potassium fulvate can improve the soil.
Humic acid is an organic substance with colloid. It can increase the aggregate structure of the soil, make the soil loose, the adsorption water quantity is large. It can not only pull dry, permeable moisture, prevent dankness. But also water storage, soil moisture cultivation, drought prevention, so that the soil has good water, air and heat conditions, which is suitable for seed germination and seedling growth.
Humic acid can improve saline-alkali land, especially potassium fulvate contains more active groups and large exchange capacity of salt base. It can adsorb and retain a large number of harmful cations from soluble salt in soil. Reduce the concentration of salt in soil. And reduce the harm of salt to seeds and seedlings. The application of potassium fulvate compound fertilizer can greatly improve the emergence rate and seedling rate of saline-alkali land, and grow well.
Potassium fulvate can stimulate the growth and development of cotton.
In the process of crop growth, any physiological metabolism can not be separated from the activity of enzyme. Water-soluble humic acid molecules are inhaled by the roots or leaves of crops. Which can regulate the physiological effects of plants. Increase the activities of enzyme at the end of crop roots and Glucoamylase. Increase the respiratory intensity of roots and leaves of crops, and promote the absorption of nutrients by crops.
Potassium fulvate is the regulator of cotton growth. It can promote the early root and germination of cottonseed and improve the emergence rate, especially under the condition of low temperature, the root is elongated, which leads to the developed root contact nutrient area is large and the absorption capacity is enhanced, which can make the above-ground vegetative body develop and grow, which is manifested as cotton plant height, strong stem, and the accumulation of dry matter increases. It can promote cotton leaves to increase respiratory intensity, enhance photosynthesis, which makes leaves green, and increase chlorophyll content.
Potassium fulvate can improve cotton disease resistance.
Potassium fulvate has synergistic effect on chemical fertilizer, and the effective utilization rate of nitrogen, phosphorus and potassium is low. Potassium fulvate in soil can play the role of nitrogen fixation and phosphorus release and potassium release. Especially on potassium fertilizer. One of the pathogenic factors of cotton wilt is the lack of potassium fertilizer. And potassium fulvate can reduce the absorption and fixation of potassium. Promote the release of insoluble potassium. increase the utilization rate of potassium fertilizer and increase the amount of available potassium. Potassium fulvate can chelate insoluble trace elements in cotton field to form soluble trace element chelate which is easy to be absorbed by crops, and improve cotton disease resistance.
Potassium fulvate can improve the resistance of cotton to stress.
Cotton is a disease frequently-occurring crop, improving the stress resistance of cotton is the key to control cotton wilt. The application of potassium fulvate compound fertilizer in cotton field can improve the ability of drought resistance and drainage of cotton, that is, under the condition of drought, it can save water and protect soil moisture, and can improve the air permeability and adjust the soil moisture content when there is more waterlogging or water storage. Increasing the cold resistance of cotton, the temperature is low in spring seedling, which is disadvantageous to cotton germination and growth, the application of potassium fulvate compound fertilizer can make cotton take root quickly, germinate early and seedling strong, and potassium fulvate compound fertilizer can improve cotton growth condition and enhance cotton stress resistance.
The potassium fulvate has the effect of inhibiting the bacteria.
In that process of cotton growth, many beneficial factors provide the condition of survival and activity of the Fusarium oxysporum-half-known fungus, so that the fungi invade the cotton strain to harm the cotton. The change-soil properties of the potassium fulvate have an important effect on the soil biological flora and the enzyme activity of the soil. The experiment shows that the application of the potassium fulvate compound fertilizer can increase the number of aerobic bacteria, actinomycetes and fiber-decomposing bacteria in the soil, so that the number of the fungi is obviously reduced, and the proportion of the bacteria and the fungi is obviously improved. This has no doubt as to the inhibition effect of the fungus-induced wilt pathogenic bacteria of the cotton.
The above are the main uses of potassium humate in agriculture.
