Effect of minimum tillage and crop sequence on physical properties of irrigated soil in southern Alberta.. Xiying Hao a,* , Chi Chang a ,
The objective of the studies reported in this paper was to evaluate changes in soil physical and chemical properties with time under commercial farming situa- tions where changes
Erosion in¯uences several soil properties, e.g., topsoil depth (TSD), soil organic carbon (SOC) content, nutrient status, soil texture and structure, available water holding
Even though the carbon contained in surface residues varied with til- lage practices (Table 8); tillage impacts on overall SOC storage remained insigni®cant when all residues
The treatments included three water regimes (i) shallow-water ponding (5 2 cm) throughout the crop growth period (W1), (ii) shallow-water ponding until panicle initiation and
RE1 is the standard deviation of height readings after correction for slope; RE2 is the same as RE1 but adjusted for oriented roughness up-and-down the slope; RE3 is the same as RE1
The two alternative systems, which received large inputs of compost, had higher soil organic carbon, microbial biomass, total nitrogen, total phosphorus, exchangeable nutrient
