1. Improve soil
Fulvic acid or potassium fulvic acid or organic colloids in humus form colloidal substances in the soil, which can cement soil particles together, increase water-stable aggregates in the soil, and coordinate soil water, fertilizer, gas, and heat conditions. It is very effective in improving poor soils such as sand and clay, thereby improving the ecological environment of crops. In improving saline-alkali soil, potassium fulvicate contains more active genes and has a large salt base exchange capacity, which can adsorb and retain a large number of harmful cations in the soluble salts of the soil, reduce soil salt concentration, and reduce salt content. The pH of alkaline earth. Thereby improving the ecological environment of crops.
2. Improve fertilizer efficiency
Since potassium fulvicate can adsorb, exchange and activate many mineral elements in the soil, such as phosphorus, calcium and magnesium, the effectiveness of these elements is greatly increased, thereby improving the nutritional conditions of crops. It acts as a synergist in chemical fertilizers and reduces the adverse effects of chemical fertilizers on soil physical and chemical properties.
The effect of synergizing nitrogen fertilizer is as follows: reducing nitrogen volatilization loss, promoting nitrogen absorption, and improving nitrogen fertilizer utilization efficiency.
The synergistic effect of phosphorus fertilizer is shown in: reducing the fixation of available phosphorus in the soil and playing a role in phosphorus dissolution. Convert insoluble phosphorus in the soil into available phosphorus and promote the absorption of phosphorus by crops. Improve the effective utilization rate of phosphorus fertilizer, promote the transformation of organic and inorganic phosphorus in the soil, increase the movement distance of phosphorus in the soil, and stimulate the development of crop root systems.
The synergistic effect on potassium fertilizer is as follows: it can reduce the absorption and fixation of potassium in the soil and improve the utilization rate of available potassium. Promoting the release of insoluble potassium and increasing the amount of available potassium can alleviate the adverse effects of potassium fertilizer on soil and crops, and have a good effect on improving crop quality.
It also has obvious synergistic effects on trace elements. Stimulate crop growth Potassium fulvic acid contains a variety of functional groups. As a physiologically active substance, it can stimulate the growth and development of crops and physiological metabolism in the body. Inorganic fertilizers do not have this property.
3. Promote plant growth
Potassium fulvic acid can promote seed germination and increase seedling emergence and seedling establishment rates. It has a special promotion effect on the development of crop root systems, causing seedlings to take root quickly, produce more secondary roots, increase root mass, and elongate the root system, thereby increasing the ability of crops to absorb water and nutrients. The stimulating effect of potassium fulvicate shows vigorous growth, plant height, and strong stems on the above-ground parts of crops, especially in the early stage. Potassium fulvicate is absorbed through plant roots and stimulates the physiological metabolism of plant cells, which is manifested in an increase in respiration intensity and photosynthesis intensity. Spraying potassium fulvic acid on crop leaves causes the leaf stomata opening to decrease, water transpiration to decrease, and crop root enzyme activity to increase.
4. Can enhance the stress resistance of crops
The soil, water, nutrients, temperature, light, air and other factors in the crop growth environment constitute the growth conditions of plants. Potassium fulvicate plays a buffering role, reducing the adverse effects of crop growth and has stress resistance properties. It can improve the drought resistance of crops and increase water saving ability by 30%. The effect of water conservation and moisture conservation is second only to the effect of plastic film covering. To enhance the cold resistance of crops, foliar spraying of potassium fulvic acid can improve the resistance of overwintering crops. It has the ability to prevent pests and diseases. Potassium fulvicate has a unique effect on preventing and treating pests and diseases. When used in conjunction with pesticides, it has an antibacterial and disease-resistant effect.
5. Can improve crop quality
Potassium fulvicate will have a profound impact on improving crop quality. In vegetables, melons and fruits, it can increase sugar content, increase vitamin C content, and reduce fruit acidity. In broad-leaf crops such as tobacco leaves and vegetables, it can improve the quality of leaves. In food crops, it promotes the crops to contain more low-molecular organic nutrients.
