The "sovkhozy" tended to emphasize larger scale production than the "kolkhozy" and had the ability to specialize in certain crops. The government tended to supply them with better machinery and fertilizers, not least because Soviet ideology held them to be a higher step on the scale of socialist transition. Machine and tractor stations were established with the "lower form" of socialist farm, the kolkhoz, mainly in mind, because they were at first not trusted with ownership of their own capital equipment (too "capitalist") as well as not trusted to know how to use it well without close instruction. Labor productivity (and in turn incomes) tended to be greater on the "sovkhozy". Workers in state farms received wages and social benefits, whereas those on the collective farms tended to receive a portion of the net income of their farm, based, in part, on the success of the harvest and their individual contribution.
