POWHUMUS? WSG 85 is a concentrated humic acid substance and a 100% water soluble high quality plant growth stimulant and soil conditioner. It can be applied to agricultural and horticultural plants by soil and foliar application. Furthermore it is a permanent humic substance which cannot be easily decomposed by soil microorganisms. It can be used alone or mixed with most fertilizers.

POWHUMUS? WSG 85 is obtained through alkaline extraction from German leonardite (highly oxidized lignite). It arises from chemical and biological humification of plants and other organic matter, out of biological activity and geological processes. Leonardite provides a very high content of humic and fulvic acids and natural biological active trace elements.

POWHUMUS? WSG 85 is a growth stimulant and soil conditioner useful especially for sandy and clay soils. Due to its crystalline granular form it can be transported easily. Moreover, it can be applied to all agricultural and horticultural plants.POWHUMUS? WSG 85 is able to enhance the performance of fertilizers and thus reduces input costs.  

• Increases yield and improves quality of plants
• Improves soil structure and increases water holding capacity
• ?Increases and stimulates beneficial microorganisms
• Enhances soil cation exchange capacity (CEC)
• ?Increases the efficiency of fertilizers and reduces nutrient leaching
• Promotes root development
• Increases nutrient uptake
• Acts as a natural chelator for microelements in alkaline soils and increases their availability for plants
• Decreases drought- and pesticide-induced stress
• Increases seed germination and enhances development of radicles
• Reduces residues of herbicides and toxic substances in soil
• Delays the decomposition of ultraviolet unstable agents
