Origin:
Powhumus WSG-85® is gained through alkaline extraction from German highly oxidized lignites (known as Leonardite). It arises at the chemical and biological humification of plant and organic matter and by the biological activity of micro-organisms. They provide a very high content of humic and fulvic acids and natural biologically active trace elements.Benefits:
Powhumus WSG-85® is a growth stimulant and soil conditioner especially for sandy and clay soils. As a crystalline granule, it can be transported easily. It can be applied to all agricultural and horticultural plants. It can enhance the performance of fertilizers and reduces input-costs.Direction For Use:
Powhumus WSG-85® is 100% water soluble and it will not block the nozzles of irrigation systems, as the particle size of the suspension is <100 microns. It is suitable for direct application or you also can mix it with soluble fertilizer formulations like soluble NPK, DAP or urea and also with herbicides. It can be applied by sprinkler, drip or surface irrigation systems. First mix the recommended amount with pure water and fill it in the mixing tank. We recommend a miscibility test before the first application of a mixture.
