Agroecological evaluation of the state of the fallow lands in Small Polissya of Ukraine

Abstract

As a result of carrying out the land reform in Ukraine, 5–8.5 million hectares of arable land, fully regenerated into fallow lands, were withdrawn from the active agricultural usage. The purpose of our researches was evaluation of the vegetation and soil cover’s agroecological state of the fallow lands in the natural area of Small Polissya on different stages of suссessive changes. Route investigations and layout of control areas resulted in finding out the compositionof species, bioecological structure, stages of suссessive changes, feeding value and bioproductivity of vegetation. The basic agricultural chemistry indexes of selected soil samples were determined in the laboratory conditions.
