Outstanding Merits

• To increase organic matter in soil, improve the soil structure and benefit microbiological activity
• To enhance soil capacities of water holding, cation exchange and pH buffering
• To improve the effectiveness of fertilizers and pesticides
• To increase nutrient uptake through the leaves and roots, promote plant growth and root development
• To elevate plant stress tolerance against different biotic and abiotic stress

Specifications

Note: Product particle diameter, humic acid content and K₂O content can be customized.

Product Usage

Potassium humate can be used by soil application (fertigation) and foliar application. Besides, it can be used as additive or synergist for fertilizers, nutrients and pesticides. A compatibility test is recommended for such combination before first application.
