Short-Term İmpacts of Biochar Applications on Physico-Mechanic and Chemical Properties of Two Contrasting Textured Soils

The effect of biochar applications on soil properties varies significantly depending textures. Therefore, a pot experiment was carried out to investigate the effects (BC) amendment some physico-mechanic and chemical properties, such as bulk density (BD), particle (PD), mean weight diameter (MWD), aggregate stability (AS), Attarberg limits, pH, electric conductivity (EC), organic carbon (OC), total nitrogen (TN), C:N ratio two different textured calcareous soils (Clay Sandy Loam). Biochar produced from sunflower residues were mixed with at rate 0, 1, 2 4%. All pots watered field capacity incubated for 30 days. results showed that improved structural both studied soils. Although (MWD) increased in clay soil, it decreased sandy loam soil. liquid limit by an increment BC application rates soils, plastic single affected selected decreasing increasing EC, OC, TN, C: N ratio, but no detected CaCO 3 content Organic mineralization amended BC, however, compared control sample. As conclusion, However, inconsistent
