GENERAL KNOWLEDGE

Detailed explanation-1: -Tillage is defined as the mechanical manipulation of the soil for the purpose of crop production affecting significantly the soil characteristics such as soil water conservation, soil temperature, infiltration and evapotranspiration processes.

Detailed explanation-2: -Depending upon the purpose or necessity, different types of tillage are carried out. They are deep ploughing, subsoiling and year-round tillage. Deep ploughing turns out large sized clods, which are baked by the hot sun when it is done in summer.
