Some soil-environmental consequences of long-term chernozem irrigation

Abstract

The present paper includes the results of investigations of influence of various agro irrigation factors on the character of degradation changes of main chemical characteristics of carbonate chernozem. On the basis of performed laboratory analyses it has been established that long-term imperfect technology of sprinkling lead to degradation changes in calcium-carbonate system of the irrigated chernozem, as well as to its dehumization, which induced, as a consequence, also the degradation of soil physical state.

U ovom radu prikazani su rezultati istraživanja uticaja različitih agroirigacionih faktora na karakter degradacionih promena osnovnih hemijskih osobina karbonatnog černozema u zalivnom sistemu 'Donje polje' u Surčinu. Na osnovu sprovedenih laboratorijskih istraživanja utvrđeno je da je višegodišnja nesavršena tehnologija orošavanja dovela do degradacionih promena u kalcijum-karbonatnom sistemu navodnjavanog černozema, kao i do njegove dehumizacije, što je imalo za posledicu i degradaciju njegovog fizičkog stanja.
