Investigating the Effect of Biochar on Physical and Chemical Properties of a Silty Loam Soil

The purpose of this study was to investigate the effect of olive oil on physical and chemical properties of soil including bulk density, total porosity, weight, moisture content, saturation moisture content, EC and pH . The results of the comparison showed that treatments at 700° C, one and two percent biohardary with the highest apparent density and treatment at 500 ° C, and 4% biochar have the lowest density. Treatments at 700 ° C, one and two percent biohardary with the highest apparent density and treatment at 500 ° C, and 4% biohazard have the lowest density. With increasing pyrolysis temperature, the apparent density has increased. Also, 500oc treatment, four hundred batches had the highest porosity and treatments of 700 oc, twe percent buckling with the least porosity. The saturated moisture content in the treatments 300, one and 500 oc, 4%, respectively, had the highest and lowest values respectively. Treatment at 500 ° C, 4% treatment had the highest available water and treatment at 700 ° C, without water, one percent had the lowest available water. With increased bioavailability, the amount of available water has increased. The results show the efficacious effects of biocurrent on physical and chemical properties of soil with medium texture.
