THE CONTENT OF TRACE ELEMENTS IN SALINE SOIL AND COTTON PLANTS UNDER APPLICATION OF BIOPREPARATIONS RIZOKOM-1 AND SERHOSIL

The article presents the results of research of the influence of two biopreparations RIZOKOM-1 and SERHOSIL on the content of trace elements such as zinc, copper and arsenic in cotton plants and saline soils. It is noted that the content of these elements was within the normal range and toxic effects on plants was not found in experimental variants under the influence of biopreparations RIZOKOM-1 and SERHOSIL. Application of biopreparations contributed to the improvement of the saline soils under cotton, which has a positive impact on the yield of raw cotton, yield was up by 13.4 с/ha in comparison with the traditional sowing of cotton.
