Answer 2

1. Subsoil is the layer underneath the surface topsoil, which consists of greater minerals and materials of iron and aluminum compounds than topsoil. ... The subsoil tends to be more compact than topsoil, since it does not hold any air in the soil.

2. Alluvial soil is mostly confined to the Great Northern plains and the coastal plains and support many crops like rice and wheat. Black soil is found mostly in the northwestern part of the peninsular plateau mainly in Maharashtra and parts of Gujarat and cotton grows best in this soil

3. Terrace farming is the practice of cutting flat areas out of a hilly or mountainous landscape in order to grow crops. ... Strip cropping is a method of farming which involves cultivating a field partitioned into long, narrow strips which are alternated in a crop rotation system.
