Abstract :Effects of different cover crops insert ignore into journalissuearticles values(CCs);, mechanical cultivation and herbicide treatments on some soil chemical properties [pH, EC, total N, available P, exchangeable cations insert ignore into journalissuearticles values(Ca, Mg, K, Na); and the DTPA-extractable micronutrients insert ignore into journalissuearticles values(Fe, Mn, Zn, Cu);] and basal soil respiration insert ignore into journalissuearticles values(BSR); were investigated in a cherry orchard from 2013 to 2014. The present study was conducted in a cherry orchard located at the Experiment Station of Black Sea Agricultural Research Institute in Samsun province on the Northern side of Turkey. CC treatments, included 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);. Control treatments included mechanical cultivated insert ignore into journalissuearticles values(weed-free);, herbicide treated insert ignore into journalissuearticles values(weed-free); and control plots, i.e., bare ground plots insert ignore into journalissuearticles values(with no cover crop); were allowed to become weedy. The experiment was conducted in a randomized complete block design with four replicates. The CCs were mowed in the flowering stages of the plants. After 90 days following seed harvest, soil samples were collected from two depths insert ignore into journalissuearticles values(0-20 and 20-40 cm); in each plot. All cropping species showed positive effects on soil chemical properties and BSR. The CC treatments decreased soil pH and exchangeable Na and increased EC, total N, available P, exchangeable cations insert ignore into journalissuearticles values(Ca, Mg, K); and the DTPA-extractable micronutrients insert ignore into journalissuearticles values(Fe, Mn, Zn);. Effects of mechanical cultivation and herbicide treatments on soil chemical properties and BSR values were not found significant for both soil depths as compared to control insert ignore into journalissuearticles values(p<0.01);. Results of the study showed that CCs, especially TR and VV treatments as legume plants improved soil chemical properties and BSR values in short term period. However, longer term studies are needed to evaluate the long-term effects of these sustainable management practices which have the potential to improve soil quality variables are encouraged.Keywords : Basal soil respiration, cherry orchard, cover crops, macronutrients, micronutrients
