Thus, huge savings in labor have accrued from engine-driven mechanization systems in the developed world, which in turn have been rapidly followed by rural depopulation. The societal impact of rural depopulation has not been adequately addressed.
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.
