1、[Effects of different application amounts of potassium fulvic acid on

The results showed that applying 1.5 to 2.25 kg·hm~ (-2) of potassium fulvic acid per hectare could effectively improve the yield of F. thunbergii and there was significantly difference between potassium phosphate monobasic and potassium fulvic acid in terms of quality.

2、Integrated application of inorganic fertilizer with fulvic acid for

In this study, pot experiment was conducted to evaluate the effects of N fertilizer and in combination with fulvic acid (FA) on NUE and nutrient supply in a moderate-salinized soil (with total salt content 3.30 g kg−1 and EC 1:5 1.18 dS m −1).

3、Potassium Fulvic Acid Fertilizer

There are mainly two sources of fulvic acid: one is mineral-derived fulvic acid, and the other is biochemical fulvic acid. Fulvic acid from minerals is an organic fertilizer and soil amendment that is used to fix agricultural soil problems.

Potassium Fulvate is highly active fulvic acid processed through the edging technology with lower molecular weight, more functional groups such as hydroxyl, carboxyl, and phenolic hydroxyl, and excellent performance on deflocculation. Better soluble in hard water and acid conditions.

Understanding Mineral Potassium Fulvate

Higher concentration & efficiency: Only about 1kg per acre of mineral potassium fulvate is needed for basal application, whereas biochemical forms may require 10–20kg to achieve similar effects.

Fulvic Acid and Potassium Application to Mitigate Drought

These findings highlight the potential of fulvic acid combined with an adequate potassium level for improving crop performance under drought conditions.

Better Nutrient Absorption: The fulvic acid grabs onto nutrients like iron, zinc, or potassium and carries them into plants, making fertilizers work better. This can reduce fertilizer use by 20–30%.

Potassium Fulvate Fertilizer

Potassium fulvate fertilizer is primarily composed of fulvic acid, a low-molecular-weight organic compound (300–500 Daltons) formed through the microbial decomposition of organic matter.

Fulvic acid has strong biological stimulation for crop growth and its small molecule structure let the plant absorb easier and better. The organic combination of both has better effect for the crop and has good solubility with NPK water-soluble fertilizer.

How to Use Mineral Potassium Fulvate Fertilizer

Avoid excessive use of potassium fulvic acid from mineral sources to avoid negative effects on crops and soil. Mineral potassium fulvate should be stored away from moisture and exposure to avoid affecting the fertilizer efficiency.

Potassium fulvic acid is an efficient organic-inorganic compound fertilizer containing multiple nutrients that promote plant growth and development. The purpose of using potassium fulvic acid at Mining Institute is to enhance soil fertility and increase crop yields.

The frequency of applying potassium fulvic acid monthly depends on factors such as soil fertility, crop growth stages, and climatic conditions. Generally, when initiating planting or transplanting crops in spring, potassium fulvic acid can be used as a base fertilizer to improve soil water retention and nutrient-preserving capacity. During the crop growth period, it can be applied periodically based on actual conditions to replenish soil nutrients.

If soil fertility is poor or crop growth is slow, the application frequency of potassium fulvic acid can be increased appropriately for better results. For example, after autumn harvest, if the soil lacks nutrients, applying potassium fulvic acid during winter can supplement soil fertility.

Key considerations for using potassium fulvic acid include:

1. Select high-quality products: Choose reliable, fully formulated potassium fulvic acid to avoid adverse effects on crops from inferior products.

2. Adjust dosage based on soil conditions: Soil fertility varies, so application rates differ. Typically, 5-10 kg per mu (approx. 0.067 hectare) is sufficient.

3. Timing matters: Apply potassium fulvic acid early in the crop growth stage to promote root development and nutrient absorption. Reduce dosage in later stages to avoid disrupting normal growth.

4. Avoid over-fertilization: Excessive use may burden the soil, leading to compaction, salinization, or other issues. Control dosage strictly.

5. Combine with other fertilizers: Mix potassium fulvic acid with organic fertilizers (e.g., chicken manure, cow dung) to enhance efficiency and effectiveness.

the optimal monthly application frequency of potassium fulvic acid at Mining Institute should align with soil fertility, crop stages, and climate. Prioritize high-quality products, adjust dosages, time applications properly, avoid excess, and integrate with other fertilizers. With scientific management, soil fertility and crop yields can be effectively improved.
