DISTRIBUTION OF GROSS FORMS OF ELEMENTS IN SOILS AND DOMINANT PLANTS OF AGROCENOSIS TRITICUM AESTIVUM L.

Abstract

The aim of this work was to study the distribution of gross forms of elements - Ca, Mg, Sr, Ni, Cr, Zn, Mn, Cu, Fe, Pb, Cd, Co, As in the soil and plants of roadside agrocenosis. Agrocenosis Triticum aestivum L. is located along the Federal highway P-404. Sonchus arvensis L. and Cirsium setosum (Willd) Bess. are dominant weed species of agrocenosis, have a similar elemental composition. Phytomass of these plants does not accumulate As, Cd, Co, Ni, Cr, Zn, Cu, Mn, Pb. The content of Ca, Mg, Sr, Fe does not depend on the removal of the roadbed. Triticum aestivum L. - the main crop of agrocenosis, does not accumulate in its phytomass As, Cd, Co, Ni, Cr, Zn. The concentrations of Ca, Mg, Sr, Mn, Cu, Fe, Pb in the phytomass of Triticum aestivum L. are not dependent on the location of the road and are in the same range over the entire area of the field. The approach to the roadbed at a distance of 15-200 m did not affect the salt composition of the soil; the pH of soil samples taken over the entire field area is neutral. As, Cd, Co in soil are not detected. The value of the gross forms of Cr, Cu, Sr, Zn, Fe in soil does not exceed the value of their clarkes in the lithosphere. The content of gross forms of Pb and Mn in soil does not exceed the maximum allowable concentration. The approach of the road did not have a critical impact on the elemental composition in the components of the roadside agrocenosis.
