This study was conducted in Bursa Uludağ University, Faculty of Agriculture, Department of Soil Science and Plant Nutrition. The effect of biochar applied at increasing levels (0-500-1000 and 2000 kg da-1) on soil properties was determined in the incubation study carried out under greenhouse conditions.Soil samples were taken from pots on 1, 30, 60, 90, 120 and 150 days in incubation study. pH, EC, organic matter, NH4-N and NO3-N, some microelements and heavy metal contents, especially P and K were determined. According to the results of the study; pH value varied between 7.68 and 7.56 depending on time and application levels. The EC value increased and varied between 692 and 1742 μS cm-1. Organic matter content of soil varied between 1.32% and 1.99% depending on application level. NH4-N and NO3-N contents were increased depending on the application levels. The amount of NO3-N over time showed higher values in biochar applications than the control application. The amount of P and K available increased with respect to the control application. The effect of biochar applications on soil microelement and heavy metal content was found statistically significant.
