Tillage is the manipulation of the soil into a desired condition by mechanical means; tools are employed to achieve some desired effect (such as pulverization, cutting, or movement). Soil is tilled to change its structure, to kill weeds, and to manage crop residues.
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.
