“…Decrease in SOC concentrations with depth has been found extensively in other studies, not only for agricultural soils such as OG (Novara et al ., ; Parras‐Alcántara et al ., ; Lozano‐García & Parras‐Alcántara, ) but also under other crops such as wheat, beans or maize (Hernanz et al ., ; Jemai et al ., ) and in dehesas and rangelands (Pulido‐Fernández et al ., ; Parras‐Alcántara et al ., ) and natural soils in Mediterranean areas (Rovira & Vallejo, ), even into soils forming in old mine lands (Brevik, ).…”

“…Indeed, lack of mechanical operations under ZT leads towards progressive densification and reduced pore volume (Du et al, 2010;Jemai et al, 2012), which enhances the soil bulk density (Xu and Mermoud, 2001; Thomas et al, 2007) due to soil compaction. ZT induces more soil compaction in the upper layer than CT (Braim et al, 1992;Thomas et al, 2007).…”

“…When comparing the two co-incorporation treatments based on 5-yr average, there were similar grain yields but significant reduction of N and K uptake in late rice plants in the treatment with high stubble return (F 80 RhMv) than in the conventional return (F 80 RsMv) (Tables 2 and 3). This was not the situation in semiarid and arid areas where high stubble retention of cereal straw (e.g., wheat) could reduce water losses from evaporation and improve the field microenvironment of subsequent crop growth (Jemai et al, 2012;Dikgwatlhe et al, 2014). The inconsistency indicated that high stubble retention of cereal straw might differentially affect the soil properties in dryland and lowland areas.…”
