Along these two lines, the collectives and the state farms, there will be developed the complete collectiviza- tion of the Soviet village. One of the most important developments in the col- lectivization movement was the creation of machine- tractor stations which had their first trial on one of the state farms, Shevchenko, in the Ukraine. This experi- ment, whose initiator was A. M. Markevich, an agrono- mist, spread widely and received the support of the Soviet Government. A machine-tractor station, ac- cording to the definition of Markevich, is a center for all the mechanical power and the technical equip- ment necessary for supplying to the fullest extent the production needs of agricultural enterprises. This makes possible an immense economy in technical means of production, their maximum utilization through machine-tractor stations within the limits of a radius of more than 15 to 20 kilometers. Collective farms, which have been organized on ter- ritory served by a machine-tractor station, enter into agreements with the latter as to conditions for the cultivation of the fields of the collective farms by the machine-tractor station. The agronomic aid rendered by the machine-tractor stations and the enlisting of members of the collective farms into the working staffs of these stations decidedly transform the aspect of the countryside served by these stations. Machine-tractor stations first of all lead to the growth of the sown area and to the bettering of production. Thus, in the Berezov district on farms served by machine-tractor stations and organized in 1928, the planted area in- creased as much as 28.4 per cent, while in villages not served by stations the planted area either remained unchanged, or increased on the average about 4.5 per cent. ry
