Soil was incubated aerobically for up to 80 days to investigate the effects of temperature, moisture and organic residues (Alfalfa,Sewage,Cow manure and Glucose) on the soil aggregates during the incubation period. In general as the temperature increased (10 to 55 hundred Centigrate),granulation and the time required for maximum aggregation to occure decreased. Resistant organic materials compared with more readily decomposable types were relatively more effective at high than at low temperatures. Under 80 saturation condition, organic residues were much less effective in improving soil structure than when the soil was 20-60 saturated with water
