use of natural extracts of tannins and tannin acts to improve the fertility of soil and determine a starter effect on crops, and fitocomplesso of tannins and non tannins for that use.

摘要

A use of a tannin and non-tannin material phytocomposition, either in a dry or liquid form, applied to the seedling seeds or seedling agamic multiplication members, or to implanted seedlings, to promote the starter effect, i.e. strong stimulation of the seedling initial growth. The phytocomposition is made by leaching a biomass of one or more of the following species: Castanea spp., Juglans spp., Eucalyptus spp., Quercus spp., Salix spp., Vitis spp., Mimosa ssp., Schinopsis spp., Olea europaea, Onobrychis viciifolia, Rhamnus spp., Artemisia spp., Lawsonia inermis, either in a single form or in a mixture in all mixing ratios.
