For the plantation cultivation of vegetable crops, it is necessary to carry out a comprehensive substrate analysis in order to confirm the optimal dose of AGROVIT and other additives necessary for any potential corrections to soil substrate parameters. A sample of substrate is taken after the harvest (autumn) in order to correct basic soil parameters prior to agricultural operations and to apply the first 70% of the necessary dose of AGROVIT. The remaining dose of 30% is applied immediately before planting or sowing. The average dose of AGROVIT for vegetables is from 45-60g/m2.
