Precision seeders place single seeds at predetermined intervals in evenly spaced rows to provide an optimum plant population using pretreated seeds suited to mechanical metering under gravity and with high germination and establishment potential. Plants with lesser germination potential or those requiring an earlier growing date (rice, tomatoes, cabbage, lettuce, tobacco) may be transplanted typically in biodegradable containers in which the seedling has been established in greenhouses.
Japanese technologists have pioneered the state-of-the-art technology in mechanized transplanting, which hitherto had been (and still remains) a highly labor intensive operation. Exciting innovations have occurred in sowing including the use of air pressure in precision seeders (both positive and negative, e.g. vacuum seeders), monitoring of seed metering and sowing rates using sensors, and fluid drilling (a method of sowing pregerminated seed suspended in a pumpable gel).

For example, the operation of the individual pieces of equipment must be coordinated properly in order to enhance productivity and efficiency. Another trend is precision agriculture (Figure 1), where state-of-the-art control and automation technology can be used to apply the optimum amount of seeds, water, fertilizers and pesticides to maximize economic return and minimize environmental damage. Maintaining working conditions and optimal performance of agricultural equipment is of vital importance in agricultural and food production due to the timeliness factor.
Local autonomous power supply systems are generally limited to stationary applications which, although of vital importance to farm mechanization, still represent a considerably smaller fraction of total energy than that used in mobile mechanization systems powered by tractors and other engine-driven vehicular equipment.
