A practitioner of agricultural science who advises agriculturalists. This is a rare profession. Where it is customary to produce all goods via nanofac, nanofab technology can produce sufficient quantities of any desired organic commodity, provided the templates are available. Where agriculture is part of the local system of production, and in those large orbitals that for romantic, culture or memetic reasons set aside areas of land surface for cultivation, ai governors, expert systems, and subsentient and turingrade bots, synsects, and gengineered organisms do all the work of cultivation and preparation of foodstuffs; agriculturalists' primary role is creative and managerial, and they rely primarily on their own knowledge or on consultation with expert systems rather than on the services of an agricultural scientist. Prim worlds and habs where old-style agriculture is still predominant are generally closed to outsiders and rely on well established traditional methods, and there too an agricultural scientist has no particular role.
