Characterization of Soil Physical Resilience by Index Properties and Strength Characteristics of selected Indian Soils

The stability (resistance and resilience to disturbance) of a soil system is a key factor influencing ecosystem properties and processes. Soil quality and soil resilience are interrelated but dissimilar attributes. Soil physical resilience is more acute and problematic in nature as it requires long time duration for bouncing back to its original state. Some index properties like plasticity, swell-shrink potential, compaction, maximum dry density and strength characteristics of soil are very important for estimation of soil physical resilience. There is significant correlation between soil strength characteristics and clay content of the soil.Study indicated that Alfisol has better resistance and resilience than Vertisol and Inceptisol. Fly ash and organic amendments had significant favourable effect on soil resilience
