Lease, acquisition, irrigation improvements, description           In connection with the follow-on lease we executed upon our acquisition of Sycamore Road in July 2014, we were required to make certain irrigation improvements on the property to increase overall water availability. As of December 31, 2015, these improvements were substantially complete, and we have expended or accrued approximately $933,000 related to the project. Upon finalizing the total cost of these improvements, as stipulated in the lease agreement, we will earn additional rent on the total cost commensurate with the annual yield on the farmland.
