THE EFFECT OF CONSERVATION TILLAGE ON WATER REGIME IN SANDY LOAM SOIL

In our long-term soil tillage experiment Situated in Lower-Austria, the effects of conservation tillage systems on soil physical properties, hydro-physical characteristics and crop yield were examined in maize monoculture during ten years. Even though the results of bulk density and penetration resistant measurements show that direct drilling resulted soil compaction in topsoil in contrast with ridge tillage and conventional tillage. in case of crop yield were not considerable differences between the tillage treatments thanks to the soil moisture and plant available water content.
