Abstract: Abstract The resilience of soils under varying litter quality is unclear. Therefore, this study investigated the effects of different litter sources on soils with low ( 0.05) effects within a soil type. An increase in macroaggregation increased MWD, WSSI values and large and small aggregates distribution. Aggregation was significantly higher in soils with higher clay content than sand content, suggesting that soil texture was highly influential to the litter effects on SA. We concluded that the rate of soil aggregate reformation was influenced by soil type × time interactions which determined the extent and dynamics of macroaggregation during the 30 weeks of incubation.
