Rights of a lessee regarding improvements he/she introduced on leased premises

Dear PAO,

I entered into a lease contract over a parcel of land for a period of seven years, renewable upon the agreement of the parties. I made renovations and improvements to the land. There is no provision in our contract regarding whether I will be reimbursed. Will I be able to claim a reimbursement from the lessor at the end of the term of the lease for the value of the improvements that I made?
