Potassium fulvic acid for plant

Potassium fulvic acid fertilizer is a pure natural mineral, active potassium fertilizer. It is also a highly efficient small molecule organic compound. It can stimulate plants to take root quickly, take root more, increase chlorophyll, and have stronger resistance to drought, cold, disease, and lodging. It is also fully water-soluble and acid- and alkali-resistant. It can also be co-dissolved and compounded with a variety of trace elements and macro-elements and can be applied in a variety of ways.

I. The role and efficacy of potassium fulvic acid fertilizer

1. Enhance plant stress resistance

The stress resistance of crops refers to the ability to resist adverse factors, such as resistance to diseases and insects, drought, lodging, cold （heat）, and continuous cropping. This is because potassium fulvic acid fertilizer can buffer the adverse effects caused by soil, water, temperature, and light, overcome adverse factors, and continuously deliver sufficient nutrients to the plants, so that the plants grow strong, and their own stress resistance is also enhanced. It is manifested in the reduction of the incidence of diseases and insects, no fear of frost damage, and rarely lodging. Ultimately, the yield of agricultural products is increased, and the quality is excellent.

2. Improve soil

The application of potassium fulvic acid fertilizer to the soil can form a colloidal substance in the soil, which can cement the soil particles, increase the water-stable aggregates in the soil, and improve the water, fertilizer, gas, and heat conditions in the soil. The soil is loose and breathable, and the ability to retain fertilizer and water is enhanced, so the soil fertility is improved. Especially for the improvement of clay soil and saline-alkali soil, the effect is more obvious.

By applying potassium fulvic acid fertilizer, the organic matter content of the soil increases, providing a good environment for beneficial microorganisms. The beneficial microbial population gradually develops into a dominant position, inhibiting the development and growth of harmful pathogens. In addition, the plant grows in good soil, and its disease resistance is also strengthened, reducing the occurrence of diseases and insects. Therefore, potassium humate is also an ideal fertilizer for activating the soil and eliminating diseases caused by repeated cropping.

3. Improve fertilizer efficiency

Potassium fulvic acid fertilizer has the functions of nitrogen fixation, phosphorus dissolution, and potassium activation. This is because potassium fulvic acid fertilizer can absorb, exchange and activate many mineral elements in the soil, such as nitrogen, phosphorus, potassium, calcium, magnesium, etc., greatly increasing the effectiveness of these elements, reducing the impact of chemical fertilizers on the physical and chemical properties of the soil, and thus improving soil fertility. It can reduce the volatilization of nitrogen in nitrogen fertilizers in the soil, especially for urea, which has the effect of prolonging the fertilizer effect. The synergistic effect on phosphate fertilizers is manifested in: reducing the soil’s fixation of phosphorus elements, playing a role in phosphorus dissolution, converting insoluble phosphorus in the soil into effective phosphorus, increasing the effective phosphorus content in the soil, and improving the utilization rate of phosphate fertilizers. The synergistic effect of potassium fertilizers in the soil is mainly manifested in reducing the soil’s absorption and fixation of potassium elements, making insoluble potassium active and turning it into a nutrient that can be absorbed by the root system. Thereby increasing the utilization rate of potassium fertilizers and making plants grow more vigorously.

II. Usage and dosage of potassium fulvic acid fertilizer

1. Base fertilizer: Mix with organic fertilizer or compound fertilizer as base fertilizer for spreading and turn it into 20-30cm of soil layer,50kg per mu.

2. Topdressing:10kg per mu for spraying and drip irrigation.

3. Seed dressing:0.3-0.5% of the seed volume for corn and wheat.

III. Precautions for potassium fulvic acid fertilizer

1. It cannot replace conventional fertilizers but is only a “synergist” for fertilizers. It should be mixed with conventional fertilizers when used. But it cannot be mixed with acidic fertilizers.

2. It cannot be used during the flowering period of crops. It should be used as base fertilizer or used during the seedling and fruit expansion period. Topdressing should be used in small amounts and multiple times to avoid burning seedlings.

3. When compounding, it should be used as soon as it is compounded. It should not be used for more than 12 hours after compounding.

4. Foliar spraying should be diluted twice. First, make a mother solution and then add water to dilute to prevent leaf burning. The prepared mother solution should be used while being prepared. It cannot be exposed to the sun under high temperature and should be placed in a cool place. If it rains within 24 hours after spraying, spray again.

5. When mixing with other micro-fertilizers and pesticides, attention should be paid to the concentration and acidity and alkalinity. Potassium fulvic acid flake fertilizer is an alkaline substance and should not be mixed with acidic substances.
