In this research, we evaluated the short-termeffect of alley<br> cropping with reduced tillage on soil CO2 and N2O emissions and soil total organic carbon (TOC) in an almond orchard<br> under Mediterranean rainfed conditions. We compared an almond monoculture with tillage in all plot surface (MC)<br> with almond crop with reduced tillage and growth of Capparis spinosa (D1) and almond crop with reduced tillage and<br> growth of Thymus hyemalis (D2). For two years, soil CO2 and N2O were measured, with soil sampling at the start and<br> end of the experimental period. Results showed that CO2 emission rates followed the soil temperature pattern, while<br> N2O emissions were not correlated with temperature nor moisture. Soil CO2 emissions were significantly higher in<br> MC(87mgm−2 h−1), with no significant differences between D1 and D2 (69mgm−2 h−1). Some peaks in CO2 effluxes<br> were observed after tillage operations during warm days. Soil N2Oemission rateswere not significantly different among<br> treatments. Cumulative CO2 and CO2 equivalent (CO2e) emissions were significantly highest in MC. When CO2e emissions<br> were expressed on a crop production basis, D2 showed the significantly lowest values (5080 g kg−1) compared to<br> D1 (50,419 g kg−1) and MC (87,836 g kg−1), owing to the high thyme yield, additional to the almond yield. No production<br> was obtained for C. spinosa, since at least two more years are required. TOC did not change with time in MCneither<br> D1, but it significantly increased inD2 from3.85 g kg−1 in 2019 to 4.62 g kg−1 in 2021. Thus, alley cropping can contribute<br> to increase the agroecosystem productivity and reduce CO2 emissions. However, it is necessary to grow 2.
