Answer:
Physical factors
Soils – the fertility will affect the type of farming and whether or not the farmer uses fertilisers. On a loam soil arable farming usually takes place.
Relief – flat land is perfect for arable farming while steep land tends to be used for grazing animals. Over 20° it is difficult to use the machinery needed for arable farming.
Climate – the key physical factor, both rainfall and temperature are important.
E.G. Wheat needs temps of at least 15°C for 3 months and less than 750mm of rain to grow. Oats can grow at less than 15 °C and require over 1000mm of rain.
Human factors
Cost of land – if the land is expensive then farmers must farm intensively to make a profit.
Market – The farm needs to be close to its market or to routes of communication that allow the farmer to sell his goods. Also, is there demand for the product?
Tradition – farmers may have farmed in a certain way and may be reluctant to make changes .
Government – through grants, tax barriers and subsidies governments like the EU and British government can have a major influence on farming.
Technology - the increasing development of machinery, seeds and fertilisers has transformed farming - from Genetically Modified crops to the use of antibiotics in cattle.
