55% Humic Acid Potassium Fulvate Fertilizer Powder For Soil Improvement

1. Product Introduction

The fulvic acid powder produced by our company is made from lignite and weathered lignite. After potassium hydroxide is added to the fulvic acid stock solution, it is drum-dried and scraped, and then directly crushed and sieved using a Raymond mill. Compared with biochemical fulvic acid, mineral-source potassium fulvic acid is more suitable for soil degradation (compaction, salinization), crops with high stress resistance requirements (such as fruit trees, greenhouse vegetables, crops in arid areas), and plots where soil fertility has decreased due to long-term cultivation. It is especially suitable for base fertilizer. Mineral-source products are more effective in improving soil and enhancing stress resistance, and have a wide range of applications. Mineral-source potassium fulvic acid powder is not only suitable for foliar spraying, dissolves quickly, easily forms a fine solution, and has good adhesion, but is also suitable for mixing with other fertilizers and pesticides. It is easy to disperse and has high mixing uniformity.

Potassium fulvic acid powder has the following main functions:

(1) Soil improvement: regulating soil pH, alleviating salinization and compaction, promoting the formation of soil aggregate structure, and improving water and fertilizer retention capacity. It is especially suitable for remediation of degraded soil.

(2) Root promotion and efficiency enhancement: Stimulates the growth of crop roots (especially capillary roots), enhances the root system's absorption of nitrogen, phosphorus, potassium, and trace elements, and improves fertilizer utilization.

(3) Stress resistance and quality improvement: Enhances crop resistance to drought, cold, disease, and pests, promotes the accumulation of photosynthetic products, improves the sweetness, color, and flavor of fruits, and increases yield.

(4) Activates soil microorganisms: Provides nutrients for beneficial soil bacteria (such as rhizobia and actinomycetes), promotes their reproduction, inhibits harmful bacteria, and reduces soil-borne diseases.

3. Usage method

(1) Foliar spraying (quick fertilization, suitable for all crop growth periods)

Operation: Dissolve the powder in water (concentration 0.05%-0.1%), stir until completely dissolved and spray on the front and back of the leaves.

Dosage: 750-1500 grams per hectare each time, diluted with 450-750 kg of water.

Frequency: Once every 7-15 days during the growth period. Spraying before adversity (drought, low temperature) can enhance stress resistance.

(2) Flush/drip irrigation (efficient topdressing, suitable for root absorption)

Operation: Dissolve in warm water in advance (to avoid caking), then dilute with water and flush with water or add to the drip irrigation system.

Dosage:

① Fruit trees (such as citrus, apple): 3-4.5 kg per hectare each time, once every 20-30 days during the growth period.

② Vegetables (such as tomatoes, cucumbers): 1.5-3 kg per hectare each time, halved during the seedling stage, and increased after fruit setting.

③ Field crops (corn, wheat): 1500-2250 grams per hectare each time, once during the jointing stage and once during the grain filling stage.

(3) Fertilizer/seed mixing (to enhance efficiency and promote germination)

Fertilizer mixing: Mix evenly with compound fertilizer and organic fertilizer and apply as a base or topdressing, with a dosage of 1.5-3 kg per mu to enhance fertilizer absorption.

Seed mixing: Dilute 0.1%-0.2% of the seed weight with water and mix with the seeds. Dry in the shade before sowing to promote germination and root development of seedlings.

Note: When spraying on the leaves, avoid the fruit setting period of the crop to prevent the liquid from directly contacting the fruit surface and causing fruit staining.

4. Reference dosage for target crops

Mineral potassium humate powder is suitable for most crops, especially in the following crops and scenarios:

(1) Fruit trees: citrus, apple, grape, kiwi, etc., can promote flowering and fruit preservation, improve fruit quality (sweetening, coloring), and alleviate continuous cropping obstacles.

(2) Vegetables: tomatoes, cucumbers, peppers, strawberries, etc., promote rooting in the seedling stage, resist stress during the growth period (such as premature aging and disease resistance), and increase yield and taste.

(3) Field crops: corn, wheat, rice, etc., enhance lodging resistance and drought resistance, and increase thousand-grain weight.

(4) Economic crops: cotton, Chinese medicinal materials, flowers, etc., promote growth uniformity and improve commercial quality.

Noted

(1) Seal and prevent moisture during storage. It can still be used after being crushed after lumps are formed, which will not affect the effect. It needs to be dissolved in advance and then applied. It is not suitable for direct application (easy to raise dust, absorb moisture and become compacted).

(2) The amount used is not necessarily the more the better. Excessive use may cause the crop to grow too long. It needs to be used according to the recommended amount. (3) Flexible adjustments based on crop needs and soil conditions are essential. The key is to utilize its rapid dissolution characteristics and timely supplement it during key growth periods (such as seedling stage, flowering and fruiting stage, and adverse conditions) to achieve the best results.
