Abstract

The results of studying the macro and microelement composition in the soil of the Syrdarya region are presented. The content of the elements and their forms have been studied. The paper presents the results of atomic emission spectrometry in order to determine the forms of compounds and their significance for the plant organism. The chemical composition of three varieties of industrial hemp and soil has been studied. Shown intervarietal differences in technical hemp in the ability to assimilate elements. It has been established that the qualitative and quantitative elemental composition of plants of a given culture can change under the influence of biologically active substances by means of activation of adaptation to the intake of chemical elements from the soil solution. As a result of the analysis, the content of the following macro- and microelements was established in all samples Li, B, Na, Mg, Al, P, S, K, Ca, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Sn, Sb, Hg, Pb, Mo, Ag, Cd and Ba is within acceptable limits.
