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.
More recently, direct drilling operations have become more popular where the seed is planted directly into non-cultivated soil using a corn drill (Figure 5) typically for winter cereals and forage crops, or a vacuum precision drill typically for maize, soybean and sunflower. Energy conservation and reduced soil compaction are evident advantages of a system that can also combine two, three or four field operations into one.
