Machines are used for these farm jobs: preparing land, planting, tending to crops, harvesting, and transporting goods

humans began selectively breeding teosinte plants that had greater numbers of kernels, and this practice eventually gave rise to corn

dairy farmers have used selective

breeding, nutrition, technology and constant care to

increase the amount of milk a cow can produce.

This has resulted in the U.S. dairy industry produc-

ing 50 percent more milk than in the 1940s, with 62

percent fewer cows

Machines increase efficiency because of time and consistency. Machines allow farmers to cultivate multiple crops per year. Precision agriculture enables precise application of insecticides and fertilisers, minimising waste and maximising yield.

owners also use selective breeding to attain specific traits in their beef cattle. An example of a desired trait could be leaner meator resistance to illness

Increased unemployment - machines substitute human labour. High fuel and repair costs - machines are costly and require constant repair. Environmental pollution - some machines contribute to air pollution because of exhaust fumes and dust.

Selective breeding has improved farming, as it has been able to provide more and better quality food, by investing the same amount of nutrients to the plants and food to the animals, it also allowed for larger production of food with half as many animals, as seen for the milk cows in the US

a chemical that usually kills unwanted plants in farming, such as weeds and invasive species.

Fertilisers supplement natural nutrient cycles and enhance plant growth, increasing crop yields.

jia1_3 — 2025-06-09 17:06:21 UTC

Herbicides are used in agriculture to kill any invasive species that compete with the crops, this means the crops have more nutrients and can grow more and faster, increasing the yeild in the same time frame

jia1_3 — 2025-06-09 17:08:41 UTC

Herbicides can be:

expensive to apply

contaminate environment

kill no target organisms

can be toxic to humans

resistance can grow in weeds that are exposed

ach11 — 2025-06-09 17:08:53 UTC

Water pollution - fertilisers can run off into rivers causing excessive plant growth and oxygen depletion. Soil degradation - overuse can lead to soil compaction, nutrient imbalances, and soil acidification, increasing the risk of soil erosion. Chemical burn - applying to much leads to chemical burns, which cause yellowing or browning of leaves and root damage.

jia1_3 — 2025-06-09 17:11:11 UTC

Disadvantages of using insecticides are:

can negatively impact environment

can be toxic for humans

insects can develop resistance to the insecticide

can be expensive

Insecticides are chemical substances used to kill or control insects

ach11 — 2025-06-09 17:16:59 UTC

Crop protection - protect crops from damage caused by insect pests that decrease yield. Maintain crop health - insect pests can spread plant diseases, so insecticides can help maintain overall crop health and prevent the spread of pathogens. Disease Prevention - used to control vectors like mosquitoes like malaria.

jia1_3 — 2025-06-09 17:18:09 UTC

Pesticides, on the other hand, are chemicals used to kill or control pests that can damage crops. These pests include insects, weeds, fungi, and other organisms that feed on crops, reducing their yield. By killing or controlling these pests, pesticides protect crops from damage, thereby increasing their yield

ach11 — 2025-06-09 17:18:39 UTC

Insecticides help to increase yield as they protect plants from insect damage, which allows them to grow and develop more fully.
