Answers
Answer:
New developments in agriculture made many of the achievements of the Cholas possible. The river Kaveri (which was a part of the regions controlled by the Cholas) branches off into several small channels before entering the Bay of Bengal. The overflowing of the channels deposits fertile soil on their banks and also the water from them provides moisture needed for agriculture, particularly for rice crop. Only in the fifth and sixth century large scale agriculture was started in Tamil Nadu. For this purpose forests were cleared in some regions and land was levelled in some areas. Flooding in the delta region was prevented by building embankments and canals were constructed for carrying water to the fields. Two crops were grown annually in many areas money earned from trade was invested in agriculture.To support population,the Cholas took extensive step for the expasion of agriculture.
