Leonardite

Leonardite is a natural humified organic matrix, of vegetable origin, rich in humic and fulvic acids capable of increasing soil fertility and the formation of new roots. Thanks to the high degree of humification, Leonardite increases the cation exchange capacity of the soil, increasing the availability of many nutrients and microelements. The product should be mixed in the preparation of the soils, at a dose of 10 gr. for each liter of substrate.
