Organic C inputs calculated from crop yield or annual crop residue production (if not given by the authors), assuming a C content of 45% in the plant tissues. The conversion from grain yields was done using harvest indexes from Sisti et al. (2002). bSOC stocks for an equivalent mass of that of the most compacted treatment at each site. Calculated from SOC concentration and bulk density data, if not provided by the authors. cValues of P were calculated as the addition of natural precipitation and the irrigation water applied, using average irrigation doses given by the authors. dTexture data from authors (Castellanos, personal communication) MRCSP: Midwest Regional Carbon Sequestration Partnership.
