The shrinkage limit of soil is the water content of the soil when the water is just sufficient to fill all the pores of the soil and the soil is just saturated.
The volume of the soil does not decrease when the water content is reduced below the shrinkage limit. Shrinkage limit can be determined from the relation
Where M1= initial wet mass, V1= initial volume Ms = dry mass of soil V2 = volume after drying.
