HUMINSEED® Liquid is a plant biostimulant based on highly bioactive potassium humate, potassium fulvate, algae extract and zinc. The high concentrations of humic substances support the enzyme activity and metabolic processes in the seed during germination, thereby increasing germination rate. Seeds treated with HUMINSEED® Liquid can absorb the bioactive humic substances through the cell membranes, stimulating the metabolic activities of the embryo. HUMINSEED® Liquid accelerates the germination process and root development in the field.

HUMINSEED® Liquid can be applied alone or in combination with other previously tested mordants and agents.

“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.”
