Power supply may be considered as autonomous at different levels: at local on-farm level, at local co-operative level or at national level. At local level autonomous power supply may be defined as that power which is generated on-farm for local on-farm use.
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.
