Combined amendment has more C conserving potential than sole organic amendment. Relative shift in soil inorganic-N pools may have significance in soil C dynamics. Shift in meso- and micro-aggregate labile C relates with type of nutrient management. Macro-aggregate qualitative traits is relatively more important than quantitative traits. Combined amendment shifts microbial community toward fungal dominance.
