1.Product Introduction

Potassium humate is a water-soluble, black, powdery organic substance extracted from humic acid. It is a pure natural mineral-active potassium fertilizer, rich in various trace elements, rare earth elements, plant growth regulators, virus inhibitors, and other nutrients. It is widely used in horticultural crops to enhance crop growth, deepen leaf color, and improve lodging resistance.

2.Product Functions

Potassium fulvic acid has the following main functions:

(1) Promotes root development and increases germination rate

Potassium fulvate is rich in various nutrients, and new roots can be seen within 3-7 days of application. It also significantly increases secondary roots, rapidly enhancing the plant’s ability to absorb nutrients and water, promoting cell division, and accelerating crop growth.

(2) Improves fertilizer utilization

Potassium fulvate provides the necessary carbon and nitrogen sources for beneficial microorganisms in the soil, thereby promoting their proliferation, phosphorus and potassium solubilization, and nitrogen fixation. This greatly improves the utilization rate of nitrogen, phosphorus, and potassium.

(3) Enhances plant drought, cold, and disease resistance

Potassium fulvate promotes soil aggregate formation, enhancing soil’s ability to retain fertilizer and water, and strengthening plant drought resistance. It also enhances photosynthesis, increasing organic matter in plant cell sap, thus improving crop cold resistance. Developed root systems greatly enhance the plant’s ability to absorb nutrients and water, resulting in robust plants with strong disease resistance.

(4) Increased Yield and Improved Quality

Potassium fulvate is fully water-soluble, easily absorbed, and highly permeable, with effects more than 10 times that of ordinary humic acid. The active substances in fulvic acid improve the absorption and utilization rate of nitrogen, phosphorus, and potassium, greatly enhancing plant nutrition, increasing yield, and improving crop quality.

(5) Improved Soil and Resistance to Continuous Cropping

Fulvic acid combines with calcium ions in the soil to form a stable aggregate structure, regulating the soil’s water, fertilizer, air, and heat conditions. Beneficial bacteria proliferate in the soil, controlling harmful bacteria and thus improving crop resistance. It also has a significant restorative function against soil compaction and salinization caused by long-term excessive fertilization.
