In the absence of a contrary agreement, the agricultural lessee may not claim an abatement of the rent for the loss of his unharvested crops unless the loss was due to an unforeseeable and extraordinary event that destroyed at least one-half of the value of the crops. Any compensation that the lessee has received or may receive in connection with the loss, such as insurance proceeds or government subsidies, shall be taken into account in determining the amount of abatement.
