Significance of sulphur and its ratio to nitrogen in the factor of its availability by cotton

摘要

In the article results of the investigation of the influence of nitrogen to sulphur ratio on cotton yield are presented. The intensive growth of a stem great number of cotton boxes and the high yield of raw cotton on typical grey soils are provided by applying 40 kg/h of sulphur (ratio N:S is 1:0.20) or sulphur doses of 50 kg/h on meadows (ratio of N:S is 1:0,25).
