Innovations, such as the use of fertilizer, the creation of better farming tools, new methods of farming and improved crop varieties, have improved yields. The higher the yield and more intensive use of the farmland, the higher the productivity and profitability of a farm; this increases the well-being of farming families.

[9] In 2002, 50% of the U.S. wheat crop was exported, while 36% was consumed by the American population, and 10% was fed to livestock, with the remaining 4% set aside for seed.
This sheave was attached to the input shaft of the transmission. A standard 4-speed manual transmission was still used in this drive system. The operator would select a gear, typically 3rd. An extra control was provided to the operator to allow him to speed up and slow down the machine within the limits provided by the variable speed drive system.
The cultivation of crops alongside the rearing of animals for meat or eggs or milk defines mixed farming. [4] For example, a mixed farm may grow cereal crops, such as wheat or rye, and also keep cattle, sheep, pigs or poultry. Often the dung from the cattle serves to fertilize the crops. Also some of the crops might be used as fodder for the ...

Extensive farming most commonly means raising sheep and cattle in areas with low agricultural productivity, but includes large-scale growing of wheat, barley, cooking oils and other grain crops in areas like the Murray-Darling Basin in Australia.
