Black Granular Potassium Humate Granules Soluble in Water with 5-6mm Particle Size for Nutritional Supplement

Product Overview

Soilhum-K potassium humate is produced from blue coal using a specialized manufacturing process. The process begins with crushing the blue coal, which is then mixed with a sodium hydroxide (NaOH) solution. The reaction takes place in special tanks, resulting in the formation of sodium humate. The reaction solution is decanted to remove residual impurities and then dried to produce a black sodium humate powder.

This powder is then treated with a water jet, which uses mechanical energy to form sodium humate particles. After drying, sifting to remove volatiles, and sorting, the final product is packaged. This entire process preserves the active components of organic humic acids.

This product is characterized by its black color, moderate solubility, granular structure, high strength, and ease of use. It is ideal for use in slow-release systems, and its low cost makes it suitable for use as a soil amendment or industrial cleaning agent in many applications.

Fertilizer Application Methods

Basic Application: Before sowing or planting, mix with organic or chemical fertilizer and spread evenly over the soil surface, then incorporate into the soil by plowing. This application can also be combined with furrow application or planting pit application near the roots.

Topdressing: During the crop's growing season, dig a furrow near the root system and apply the fertilizer after covering it with soil, or mix the fertilizer with watering and distribute it sparingly (avoid direct contact with the roots).

Using Mixed Fertilizers: Can be mixed with granular complex fertilizer, microbial fertilizer, etc., to improve nutrient uptake by the crop and increase fertilizer use efficiency.
