The size and number of tractors is dictated by the size, nature and profitability of the farming enterprise as well as by how many (if any) operations (e.g. plowing, planting, spraying, harvesting) will be serviced by local contractors. For example, the capital cost of purchasing a harvester to harvest a small area of a moderate value crop is often prohibitive.
The performance of such wet biomass (animal waste) systems is outlined in Agriculture and Autonomous Power Supply, EOLSS on-line, 2002, and summarized in Table 3. Autonomous power supply must also include human and animal power (as discussed in Human and Animal Powered Machinery, EOLSS on-line, 2002) which, although of great relevance to small farms in the poorest regions, is otherwise declining in relative importance.
