Supplementary Material. Effects of conservation tillage, controlled traffic and regulated deficit irrigation on soil CO2 emissions in a maize-based system in Mediterranean conditions
Figure S1. Weekly average of maximum and minimum daily temperatures (ºC) and weekly-accumulated rainfall and ETo (mm) during the two agricultural seasons of this study (2016/17-2017/18) at the experimental site. Figure S2. A) Scheme of the experimental design, showing the distribution of tillage system (CTR and ZTR) and irrigation strategy (FI and RDI) treatments in each block. B) Arrangement of the three consecutive PVC collars in an elementary plot. Each group of three collars [+F, L, -F] in consecutive positions constitutes a measuring site, or unit of measure, for the two main factors (tillage system and irrigation strategy). Table S1. Number of irrigations and fortnight irrigation amount for FI and RDI treatments during the 2016 and 2017 irrigation seasons. Table S2. Daily mean, and minimum and maximum diurnal soil C-CO2 effluxes (mg m-2 h-1) measured during the three diurnal cycles in the CTR and ZTR tillage systems, and relative difference in relation to the 24-h mean for the minimum and maximum diurnal values (%; negative value = underestimation; positive values = overestimation). CV = coefficient of variation (%).
