Abstract :Effects of different cover crops insert ignore into journalissuearticles values(CCs);, mechanically cultivation and herbicide treatments on soil organic matter insert ignore into journalissuearticles values(SOM); content and some physical properties of soils were investigated in a cherry orchard with clay soil in 2013 and 2014. The present study was conducted in a cherry orchard located at the Experiment Station of Black Sea Agricultural Research Institute in Samsun province in the Northern region of Turkey. As the CCs, Trifolium repens L. insert ignore into journalissuearticles values(TR);, Festuca rubra subsp. Rubra insert ignore into journalissuearticles values(FRR);, Festuca arundinacea insert ignore into journalissuearticles values(FA);, T. repens insert ignore into journalissuearticles values(40%);+F. rubra rubra insert ignore into journalissuearticles values(30%);+F. arundinacea insert ignore into journalissuearticles values(30%); mixture insert ignore into journalissuearticles values(TFF);, Vicia villosa insert ignore into journalissuearticles values(VV); and Trifolium meneghinianum insert ignore into journalissuearticles values(TM); were utilized. Experiment also included plots mechanically cultivation insert ignore into journalissuearticles values(MC);, herbicide treatment insert ignore into journalissuearticles values(HC); and control insert ignore into journalissuearticles values(C); plot without CCs. Experiment was conducted in randomized complete blocks design with four replications. The CCs were mowed in the flowering period of the plants. After 90 d following seed harvest, soil samples were collected from two depths insert ignore into journalissuearticles values(0-20 and 20-40 cm); in each plot. The CCs treatments decreased bulk density, volumetric water content, relative saturation, penetration resistance and increased SOM, field capacity, permanent wilting point, available water capacity, total porosity, gravimetric water content, mean weight diameter, structural stability index. The differences in the SOM contents and physical soil properties of all treatments as compared to the control were not found to be significant for the 20-40 cm soil depth in both years of experiments. The CCs, especially TR and VV treatments as legume plants improved SOM and physical soil properties, but longer term studies are needed to evaluate the long-term effects.
