Transfer of agricultural land - not used for agri- purpose

Dear Friends,

  A person has purchased a Agricultural land at 1980 and the land fullfills all the conditions prescribed in Section 2(14)(iii) of the Income tax act.At the beginning he had done some agricultural activities but it didn't do well. Since it is not suitable for agriculture he could not be able to cultivate any agricultural goods. After that he did not do any agricultural or non agri cultural activites in aforesaid land. He kept it  Idle. Now he is planning to sell the land.

My question is

1) Wether Capital gain will arise?

2) Whether to qualify as per Section 2(14)(iii), Compulsorliy agricultural activites should have been done / not?

3)If capital gain is arising whether it can be invested in bonds (54EC) or any other deduction is avilable?

Awaiting....Please do reply
