Prior tenant applied fertilizer to deceased landlords farm for following crop year. Heirs offered land to new tenant for lease/purchase. Heirs specifically asked by new tenant was the farm locked in for that crop year. They said no. Premium lease with cash up front offer to cover finance time lag for requested quick sale and any "extraneous" liabilities on transaction. Finance fell thru. Farm returned to heirs after 2018 harvest. prior tenant to buy. Heirs now claiming New tenant owes fertilizer bill to prior tenant.

Who's liability??

BTW if fertilizer was a double potash application for beans it did not make a difference in yield.
