Biospektrum WG

Plant Biostimulant - organic enriched microbiological product for spraying on soil.

Biospektrum WG - is an organic enriched microbiological product that enhances plant productivity and improves soil conditions. Billions of beneficial bacteria convert nutrients (N, P, K, Si) into plants available forms available to plants and promote their uptake, which in the long run can significantly reduce the need for synthetic mineral fertilizers.
