Product Description
Humic acid fertilizers are a type of fertilizer with humic acid as the main component, and they have various functions such as improving soil and promoting crop growth.
The main component is fulvic acid, and it also contains nutrient elements such as nitrogen, phosphorus, potassium, as well as trace elements. The component contents of different types of fulvic acid fertilizers vary. For example, in mineral source potassium fulvate, the mineral source fulvic acid is usually ≥50% and potassium oxide is ≥12%; in biochemical potassium fulvate, the fulvic acid is generally >50%, nitrogen > 3%, phosphorus > 0.4%, and potassium oxide is 7 - 12%.
-
Good water solubility: Humic acid fertilizers are generally completely water-soluble with no precipitation. They can dissolve quickly in water, facilitating application through drip irrigation, sprinkler irrigation, etc., and improving fertilizer utilization efficiency.
-
Small molecular weight and easy to be absorbed: Humic acid is the part with a relatively small molecular weight in humus. It can be directly absorbed and utilized by crops, rapidly providing nutrients to the crops.

Product Advantages
-
Soil improvement: It can form a colloidal substance in the soil, promote the formation of soil aggregate structure, increase the water - stable aggregates in the soil, loosen the soil, and improve the soil's water - and - fertilizer - retaining capacity. At the same time, as a weak acid, it can form a buffer solution with monovalent cations to maintain the stability of soil pH.
-
Fertilizer efficiency improvement: It is a slow - release agent and stabilizer for nitrogen fertilizers, a synergist for phosphorus fertilizers, and a protector for potassium fertilizers. It can reduce nitrogen volatilization, decrease the fixation of phosphorus by the soil, reduce the absorption and fixation of potassium by the soil, promote the release of insoluble potassium, and improve the utilization rate of nitrogen, phosphorus, and potassium.
-
Promote crop growth: It contains various functional groups, which can stimulate the growth, development and physiological metabolism of crops, promote seed germination, stimulate root growth, enhance root vitality, and also promote the formation of chlorophyll, sugar and amino acids, and enhance the intensity of photosynthesis and respiration.
-
Enhance stress resistance: It can enhance the cold resistance, drought resistance and saline-alkali resistance of crops, and can also form insoluble substances with heavy metals, reducing the harm of heavy metals to crops.
Application
It has a wide range of applications, including fruit trees such as apples, pears, and peaches, leafy vegetables such as Chinese cabbages and lettuces, melons such as cucumbers and watermelons, as well as cereal crops such as corn and wheat, and various flowers, seedlings, etc.
Precautions
-
Most fulvic acid fertilizers are quick-acting fertilizers, generally used as topdressing. They are difficult to remain in the soil for a long time. When applying fertilizers, the principle of applying small amounts frequently should be followed.
-
The nutrient content is relatively high. Appropriate dilution is required before use to avoid burning the seedlings and roots when directly applying with water.
-
Try to avoid using flood irrigation or flowing water irrigation to prevent fertilizer loss.
