Loss Contingencies [Line Items]            
Lease, acquisition, irrigation improvements, description         In connection with the follow-on lease we executed upon our acquisition of Sycamore Road in July 2014, we are required to make certain irrigation improvements on the property to increase overall water availability by November 1, 2015. These improvements are expected to be completed during the three months ending December 31, 2015. As of September 30, 2015, we have expended or accrued $765,000 related to these improvements, and we expect to incur additional costs of approximately $85,000. In addition, we will earn additional rent on the total cost of these improvements commensurate with the then-current annual yield on the farmland.
