Meanwhile, farmland which received of transmigrant that time was 1¾ hectare (ha); one hectare of the land is for tidally irrigated rice, and ¾ hectare of the land is for dryland crop. Biside that, each transmigrant also received ¼ hectare land for home garden. Through the land which was given by government to transmigrants, before 2000, Kerta Buana village could be created as centre of paddys for Tenggarong Seberang subdistrict result of some paddyfield which made of transmigrants.
