Mechanised agriculture

[1] In modern times, powered machinery has replaced many farm task formerly carried out by manual labour or by working animals such as oxen, horses and mules.

[2] It can be summarized as a progressive move from manual tools to animal traction, to motorized mechanization, to digital equipment and finally, to robotics with artificial intelligence (AI).

[3] These advances can raise productivity and allow for more careful crop, livestock, aquaculture and forestry management; provide better working conditions; improve incomes; reduce the workload of farming; and generate new rural entrepreneurial opportunities.

[3] Current mechanised agriculture includes the use of tractors, trucks, combine harvesters, countless types of farm implements, aeroplanes and helicopters (for aerial application), and other vehicles.

[11] Although U.S. farmers of corn, wheat, soy, and other commodity crops had replaced most of their workers with harvesting machines and combines by the 1950s enabling them to efficiently cut and gather grains, growers of produce continued to rely on human pickers to avoid the bruising of the product in order to maintain the blemish-free appearance demanded by customers.

[12] Proponents argue that mechanisation will boost productivity and help to maintain low food prices while farm worker advocates assert that it will eliminate jobs and will give an advantage to large growers who are able to afford the required equipment.

[13] Extensive adoption started in the United States of America, where tractors replaced about 24 million draught animals between 1910 and 1960 and become the main source of farm power.

[14] United Kingdom first started using tractors in the 1930s, but agricultural transformation in Japan and some European countries (Denmark, France, Germany, Spain and former Yugoslavia) did not take place until about 1955.

[17][18] A study in 11 countries proves this low level of mechanization in the region, finding that only 18 percent of the sampled households have access to tractor-powered appliances.

[18] Since at least the early nineteenth century there have been concerns over the possible negative socioeconomic impacts of labour-saving technological change, particularly job displacement resulting in unemployment.

[2] Instead, innovation and incorporation of labour-saving technologies tends to take long, and automation of one task often spurs increases in the need for workers to perform other jobs.

[2] On the other hand, automation that is forcibly promoted, such as through government subsidies, could cause rising unemployment and falling or stagnant wages.

[19] The Food and Agriculture Organization of the United Nations (FAO) advises against governments implementing distortive subsidies for automation because doing so risks increasing unemployment.

[2] FAO also advises against restricting automation on the assumption that this will save jobs and incomes,[3] because it risks making agriculture less competitive and productive.

[2] Instead, the recommendation is to concentrate on creating an enabling environment to adopt automation – particularly by small-scale agricultural producers, women and youth – while making social protection available to least skilled workers, who are more likely to lose their jobs during the transition.

The New Mexico green chile crop is currently hand-picked entirely by field workers[23] as chili pods tend to bruise easily.

The equipment is expected to increase yield per acre and help to offset a sharp decline in acreage planted due to the lack of available labour and drought conditions.

[29] A new strain of grape developed by the USDA that drys on the vine and is easily harvested mechanically is expected to reduce the demand for labour.

Small farms were of insufficient size to obtain financing to purchase the equipment and within 10 years, 85% of the state's 4,000 cannery tomato farmers were out of the business.

The monoculture fields fostered rapid pest growth, requiring the use of "more than four million pounds of pesticides each year" which greatly affected the health of the soil, the farm workers, and possibly the customers.
