Abstract :In this study, we applied hazelnut husk waste that was composted by using microbial biotechnological techniques into soil in the field conditions. The hazelnut husk compost insert ignore into journalissuearticles values(HHC); was applied in two hazelnut orchards having different textures such as sandy loam insert ignore into journalissuearticles values(SL); and clay loam insert ignore into journalissuearticles values(CL); soils and used different application rates insert ignore into journalissuearticles values(0, 1.25, 2.5, 5.0, 7.5 and 10 t da -1 );.  Soil sampling was done four times in a year insert ignore into journalissuearticles values(spring, summer, fall and winter);. We investigated the effects of HHC on soil water holding capacity related to available water content of soil at both field capacity insert ignore into journalissuearticles values(FC); and permanent wilting point insert ignore into journalissuearticles values(PWP); with weight basis. Soil moisture coefficients were determined by using pressure plate and indicated as percentage weights at FC insert ignore into journalissuearticles values(-33 kPa); and PWP insert ignore into journalissuearticles values(-1500 kPa);. Our results showed that HHC doses, sampling periods and soil textures effected soil water holding capacity at both FC and PWP. In addition, FC and PWP were found the highest at 10 t da -1 application dose. Findings of this study, the huge importance of HHC that related to protect soil water without harmful to the environment emphasized.
