Biochar incorporation to the soil is an option to improve soil health; therefore, a number of studies carried out recently. The main expectation from biochar is improvement on soil physical properties due to its highly porous texture. This study was conducted to investigate the effects of different doses (0, 1, 2 % w/w) of biochar that obtained from two pyrolysis temperatures (400 and 500 degrees C). The experiment is carried out for 9 weeks long which soils from each treatment sampled at every week to determine field capacity (FC), wilting point (WP) and available water content (AWC) parameters. Results revealed that biochar incorporation is improved soil water contents of soil at FC and WP, significantly; however, AWC was not as affected. Pyrolysis temperature was not significant; no differences were obtained between 400 and 500 degrees C. In the case of soil water content is a matter, the higher temperature application is only loss of time and energy that causes contradiction with the philosophy of biochar related research. Water holding capacity of soil at both FC and WP were improved in accordance with incubation time; however, differences in AWC results were not statistically significant. Within the incubation times, the highest values were determined at the ninth week in all three parameters as FC, WP and AWC. Thus, further researches required to predict optimum incubation time.
