Abstract

This study examines the effects of the biostimulant Ecogumin on the taxonomic structure of soil microbial communities in cotton fields cultivated on typical gray soils of the Tashkent region. The influence of Ecogumin was evaluated under varying application rates of local organic and mineral fertilizers. The experimental results indicated that the combined application of Ecogumin with mineral fertilizers significantly enhanced soil microbial activity, with the most pronounced positive effects observed at fertilizer rates of N200P140K100 supplemented with 1.0 and 1.5 t/ha of local organic fertilizers.
