Sažetak
U radu su istraživanjima na farmi upoređeni uticaji organske i konvencionalne proizvodnje na sadržaj organske materije (OM) u černozemu. Preliminarni rezultati ukazuju da postoje značajne razlike između pojedinih lokaliteta. Znatno niži sadržaj organske materije izmeren je na lokalitetu Ljutovo (2,49%) u odnosu na lokalitete Čenej (3,17%) i Bačko Gradište (3,14%). U sistemima organske proizvodnje koji uključuju stajnjak, sadržaj organske materije u zemljištu je jednak ili visi u odnosu na sisteme konvencionalne proizvodnje. Najniži sadržaj organske materije izmeren je na plodoredima sa jarim ječmom, bez obzira na sistem proizvodnje i lokalitet.
Abstract
In this paper, in on-farm research, the effects of organic and conventional production systems on content of organic matter in Chernozem were compared. Preliminary results indicate that there were significant differences between some locations. Significantly lower organic matter content was measured on location Ljutovo (2,49%), compared to Čenej (3,17%) and Bačko Gradište (3,14%). In organic production systems which include manure application content of organic matter is equal or higher compared to conventional production systems. The lowest organic matter content was measured in crop rotations which include summer barley, regardless production systems or location.
