Solution(By Examveda Team)

Puddling refers to the tillage system, in which the soil is repeatedly plowed and harrowed under submerged conditions, to make it soft for transplanting and less permeable to water.
It decreases the macroporosity of clay soils and increases their microporosity thereby causing an increase in the water-holding capacity of the puddled soil.
Puddling is possible when clay % is greater than 20%.
