FIELD: agriculture. ^ SUBSTANCE: this invention relates to the method of optimum cultivated plant feeding with sulfur-containing fertilisers. The method includes determination of additional sulfur quantity demand for specific moment of time and place before and during vegetation period based on sulfur demand calculated with regard to the target yield capacity and environment differences. If there is sulfur deficiency detected and confirmed by experimental changes, land user is recommended to additionally feed cultivated plants with sulfur-containing fertilisers.
