Determination of Some Soil Characteristics Depending on Conventional and Reduced Tillage Circumstances

In this study, moisture content of soil, soil resistance, bulk density of soil, and soil porosity values were identified depending on circumstances before tillage process by conventional and reduced tillage methods. Distribution of soil particle size, mean weight based diameter of soil particles, and the change in roughness rate of field surface were also determined based on traditional and reduced tillage methods. Trials were conducted according to factorial regulation in randomized parcels. According to results of the study, the lowest bulk density and the highest porosity were obtained from reduced tillage method. Tillage method very significantly (P<0.01) influenced roughness rate. Particles with greater diameter were obtained in conventional tillage method in terms of mean weighted diameter. Compression ratio of soil arising from tillage method generally increased more in reduced tillage method. The lowest penetration resistance was obtained in reduced tillage with 0.08 MPa, the highest value was obtained in the uncultivated area with 2.56 MPa.
