Hydraulic Conductivity Values of Soils in Different Soil Processing Conditions

Abstract

This study was carried out to determine physical and hydraulic properties of soils under different land use conditions. For this purpose, 9 samples in total (3 samples from each of three different areas; dry farming (D), irrigated land (I) and pastureland (P)) were collected. Soil texture, pH, lime, organic matter, hydraulic conductivity, aggregate stability, bulk density, particle density and porosity were measured. Infiltration measurements were made at each sampling point in the field. However, while there was no difference between the hydraulic conductivity of the fields used for agricultural activities in dry and irrigated conditions, significant differences were determined between the pasture areas and the treated areas. Differences were determined between infiltration measurements of soils and land use status. Positive correlations between infiltration and organic matter, aggregate stability and hydraulic conductivity were obtained as well as negative correlation between bulk density and organic matter content. The lowest infiltration rate was obtained for pastureland soil and the highest infiltration rate for the irrigated land soil. Therefore, increasing the organic matter content of the local soils will make significant contributions to sustainable soil management.
