Farmhouse undergoing refurbishment could be available too. : Some 292 acres of arable commercial farm land, owned by the Kelham Estate, is coming up for rent - the first time since the 1970s. The current tenants of Trentside Farm in Kelham, near Newark, who farmed the predominantly arable land are retiring. It has been 45 years since this sizeable block of farmland has been available to let. It is now being offered on a five-year Farm Business Tenancy, starting from Monday, September 30.
