In 1990, the Soviet Union had 23,500 sovkhozy, or 45% of the total number of large-scale collective and state farms. The average size of a sovkhoz was 15,300 hectares (153 km2), nearly three times the average kolkhoz (5,900 hectares or 59 km2 in 1990).[4] Sovkhoz farms were more dominant in the Central Asian part of the Soviet Union.
