Introduction
Leonardite extract humic is a high-purity, high-activity natural organic soil conditioner extracted from humus-rich weathered lignite. It is rich in functional groups such as humic acid, carboxyl and phenolic hydroxyl groups. It is widely used in agricultural planting, soil improvement and plant nutrition enhancement. It has good water solubility and nutrient complexing ability.
Features
High Purity Humic Acid Content
Leonardite Extract Humic uses weathered lignite ore raw materials with a selected humus content of more than 80%. The extracted humic acid has higher activity and stronger chemical reaction ability, which is particularly suitable for improving soil structure and improving plant absorption efficiency.
Rapid Solubility
The humic acid extract has excellent water solubility and can be quickly dissolved in water at room temperature. It can be completely dispersed within 3 minutes without precipitation. It is suitable for drip irrigation systems, foliar spraying and soil improvement, which greatly improves the on-site use efficiency and nutrient conversion rate.
Highly Active Structure
Leonardite extract humic is rich in active carboxyl and phenolic hydroxyl groups, which can promote the differentiation of plant capillary roots. The root length increases by an average of 25% within one week of use. It is suitable for use in weak root systems, crop recovery period or seedling stage to improve growth rate and seedling rate.
