Sažetak
In order to study aggregate fraction distribution and structure stability of the Haplic Chernozem soils from different cropping systems of winter wheat and maize were analyzed. Cropping systems were situated in a long-term experiment carried out at the Rimski Sancevi experimental station, Novi Sad. Soils from different cropping systems were analyzed in depths: 0-20, 20-40 and 40-60 cm with wet and 0-20 cm for dry sieving procedure. The following indicators of soil structure were analyzed: dry geometric mean diameter (dGMD), structure coefficient (Ks), wet mean weight diameter (wMWD) and water stable aggregates (WSA). Based on the aggregate size fraction arrangement after dry and wet sieving significant difference was found between crops - winter wheat and maize. After dry sieving both crops showed relatively stable structure, although dry geometric mean diameter (dGMD) and structure coefficient (Ks) differ in explanation of cropping system effects on structure. After wet sieving small macroaggregates (250-2000 μm) showed greater structural stability and large marcroaggregates were lower. To preserve structure it is necessary to apply proper tillage operation and to allow soil to naturally build biological maturity that facilitate favourable aggregates and affects soils properties.
