Abstract
The aim of the study was to study the effect of various doses of chicken manure (CP), zeolite (C), their mixtures and mineral fertilizers on the accumulation of microelements in the vegetative organs of spring rape plants at different stages of development. The results of the experiment showed that the introduction of the zeolite-containing rock of the Terbunskoye deposit promoted a decrease in such trace elements as Cu, Zn and Mn in the vegetative mass of rapeseed throughout the entire period of plant development. On experimental plots using organic-mineral mixtures (CP 2.5 t / ha + C 3 t / ha, CP 5 t / ha + C 3 t / ha, CP 10 t / ha + C 3 t / ha) the active adsorption of the zeolite-containing rock of the Terbunskoye deposit in relation to Zn was revealed, which contributed to a decrease in the element in the vegetative mass of rape in the variants of the experiment throughout the entire vegetation period of plants. Consequently, the studies carried out make it possible to recommend the cultivation of spring rapeseed using organic waste as fertilizers together with natural zeolite in the forest-steppe conditions CHR.
