The development of the moldboard plow facilitated the inversion and burial of layers of surface vegetation (grass, weeds, cereal stubble), exposing a virgin soil surface which could then be further broken down into a fine seed bed by draft or power driven tined implements. The development of the multi-furrow moldboard plow powered by high-speed tractors underscores the high productivity of modern mechanization systems as compared to the single furrow plow drawn by a slow moving draft animal.
Because the direct effects of mechanization on yields are small, however, any effect of subsidies on agricultural output must be an indirect one that arises from the cost reduction made possible by machines. But when mechanization is not spontaneously driven by some form of labor scarcity, the impact on production costs is not large; the output effects of subsidies therefore cannot be large either. When mechanization is caused by subsidies, reductions in the agricultural work force can be substantial.
