Use of natural extracts of tannin and non-tannin materials for improving soil fertility and providing a starter effect on cultivations, and a tannin and non-tannin phytocomposition therefor
A use of a tannin and non tannin material phytocomposition or phytocomplex, 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.
1. A dry or liquid phytocomposition of tannin and non-tannin materials to be applied to seeds or agamic multiplication members, or to implanted seedlings, to promote the starter effect consisting of a strong stimulation of an initial growth thereof, said phytocomposition comprising a water leached biomass of at least a plant species selected from the group consisting of Castanea spp., Juglans spp., Eucalyptus spp., Quercus spp., Salix spp., Vitis spp., Mimosa spp., Schinopsis spp., Olea europaea, Onobrychis viciifolia, Rhamnus spp., Artemisia spp., Lawsonia inermis , and mixtures thereof.
2. A method for pre-sowing/pre-transplanting localization, sowing/transplanting localization, post-sowing/transplanting localization, a pre- and post-implantation localization irrigation and seed/agamic multiplication member tanning, of seeds, agamic multiplication members or implanted seedings, said method comprising coating said seeds, agamic multiplication members or implanted seedling with or mixing in a cultivation substrate or in vessels for growing transplanted plants, a phytocomposition according to claim 1 .
3. A phytocomposition, according to claim 1 , characterized in that said phytocomposition is capable of increasing an absorption of nutritional elements present in a cultivation soil or medium.
4. A phytocomposition according to claim 1 , characterized in that said phytocomposition is capable of increasing a recovery by a plant of nutritional elements present in a cultivation soil or medium.
5. A method according to claim 2 , characterized in that said phytocomposition is applied to a cultivation soil or medium having a water pH larger than 6.5.
6. A method according to claim 2 , characterized in that said method comprises a step of applying said photocomposition at a dose from 5 to 250 kg/he of said phytocomposition in a dry form thereof.
