Annual and perennial crop composition impacts on soil carbon and nitrogen dynamics at two different depths

Abstract The sustainability of an agricultural field is largely influenced by crop growth habit and management practices such as tillage. Both strongly interact to shape ecosystem properties the fluxes stocks carbon nitrogen. Recently, researchers have worked develop perennial grain crops in order enhance key processes, cycling nitrogen fixation, with use rather than traditionally used annual crops. In this study, we aimed understand how soil disturbance combined vegetation type [annual monoculture vs. monocultures (intermediate wheatgrass (IWG)) vs restored native (RNV)] dynamics. We collected samples at two depths (0–15 cm 15–30 cm) from each treatment incubated soils laboratory for 120 days determine efflux also analyzed mineralization both results demonstrated IWG had greatest flux, well storage (annual < RNV IWG). differences were 27, 40, 20%, respectively, while was 11, 20, 10%. Shallow exhibited greater all C N comparisons between treatments compared deeper samples. Taken together, our findings indicate that depth influence
