Elvita Humus contains humic acids that occur naturally in the soil hummus It is made from leonardite - a soft organic sediment, very rich in humic acids (up to 90%), so the concentration of these components is much higher in Elvita humus than under natural conditions in the soil or in organic fertilizers. This fertilizer significantly improves the structure and quality of the substrate, which, in turn, leads to much faster rooting of young plants.
