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).
Steam engines were widely used for only about fifty years between 1870 and 1920. After 1900 they were rapidly displaced by internal combustion engines and electric motors. Tractors came into widespread use in North America after about 1920, but coexisted with horses for roughly twenty-five to thirty years. Except for Great Britain, where tractors began to be adopted in the 1930s, the tractorization of European and Japanese agriculture was delayed until about 1955, after which it happened very quickly.
