Where, WSMa: water stable macroaggregates; WSMia: water stable microaggregates; WSA: water stable aggregates; MWD: mean eight diameter; AS: aggregate stability; GMD: geometric mean diameter; AR: aggregate ratio; Sc1: conventional rice-wheat system; Sc2: partial CA-based rice-wheat-mungbean system; Sc3: full CA-based rice-wheat-mungbean system; Sc4: full CA-based maize-wheat-mungbean system.

Different small letters within the same column showed the significant difference at p < 0.05 according to Duncan Multiple Range Test for separation of mean.
