HUMAGRA® NPK 6-0-10 + HA WSG is a water soluble, organic mineral fertilizer based on potassium humate (activated humic acids) from high quality German Leonardite and nitrogen. It provides the crop with plant available nitrogen and potassium for high crop yields. Due to the humic substances with their high cation exchange capacity, the nutrients are bound so that they are available for plants. Humic substances, especially in sandy soils, form the very basis for sustainable and efficient nutrient absorption by the plant.
HUMAGRA® NPK 6-0-10 + HA WSG can be applied using fertigation, hydroponic and sprinkler systems as well as conventional foliar sprays. Also suitable for hydroponic cultivation systems.

“All Humintech humic substances based products are analysed according to the HPTA test method (ISO 19822:2018) to determine the content of humic and hydrophobic fulvic acids. Most suppliers are using the more simple “colorimetric” analysis method to determine the humic and fulvic acid contents, but experience shows that, due to its inaccuracy, this method indicates higher contents and is not suited to identify non humic substances such as lignosulphonates. In order to maintain the highest quality standard, Humintech has therefore decided to use the currently best analytical standard for the determination of humic and fulvic acids within the scope of quality control.”
