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 valueswere 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 rateof field surface were also determined based on traditional and reduced tillage methods. Trials were conductedaccording to factorial regulation in randomized parcels. According to results of the study, the lowest bulk densityand 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 ofmean weighted diameter. Compression ratio of soil arising from tillage method generally increased more in reducedtillage method. The lowest penetration resistance was obtained in reduced tillage with 0.08 MPa, the highest valuewas obtained in the uncultivated area with 2.56 MPa.

Keywords:

Bulk density, penetration resistance, roughness rate, soil particle size, soil tillage,
