The processes of the change in the Rural Environments in the UK.

The processes of the change in the Rural Environments in the UK "Hi-tech farming develops higher yields at lower costs using less land". I would agree with this statement because over the past few years, precision farming has become a proven and affordable way to know your crops. Each year, more and more farmers turn to high-tech tools to collect data, process information in order to increase their yields. These hi-tech tools include Global positioning systems which allow the farmer to keep track of the crops he or she has sprayed and enables them to spray at night. It also allows them to keep track of what crops they have already harvested and where they have planted new ones. This reduces errors made by farmers that could lead to crops being destroyed and, therefore, increasing potential yield. Yield mapping will also increase yield; with a yield mapping monitor, it is possible to spot where areas of rocks or infertile land are located, which might affect crop growth. ...read more.


However, using nitrates has a negative side too. Excess nitrate leaks into groundwater supplies and can run into ponds and rivers. This can then lead to eutrophication, which is when nitrates create a nutrient rich environment which causes plants and algae to multiply rapidly. These plants then use the oxygen in the rivers and ponds, causing fish and other fresh water animals to die as there isn't enough oxygen for them to survive. It also contaminates human water supplies which is a health hazard. The Ministry of agriculture, fisheries and foods (MAFF) has confirmed that there is a link between nitrates and cancer. Phosphates from sewage and farm slurry have also caused pollution in areas like the Norfolk Broads. Biocides and other chemicals are used to kill organisms which damage crops and are otherwise known as poisons. The most common way to apply the biocide to the crops is to spray them by vehicle or by plane, this insures a healthy crop. ...read more.


4. Stubble burning: mountains of organic matter are burned and then become polluting smoke. Now farmers can move away from using chemicals and fertilizers by using different methods of farming. Farmers can now grow organic crops; they can use insect predators which help protect the crops replacing the need for chemicals. Another option is to cultivate less intensively or reward nitrate-free farming. The government can also help persuade farmers to change their methods by fining and taxing polluters higher and giving incentives to farmers who keep pollution to a minimum. Genetically modified food or GM foods are also an alternative though highly controversial crop that can cut costs to farmers and help protect the environment as they don't require pesticides. By 2009 the government have a target to make 25 percent of farming organic. The reasons for this are that it means healthier food as no chemicals are used and food production is six times more sustainable and more energy efficient. ?? ?? ?? ??

  1. Discuss the Advantages and Disadvantages of the use of Fertilisers and Pesticides in Agriculture

    The use of pesticides has also allowed growers to produce crops in otherwise unsuitable locations, extend growing seasons, maintain product quality and extend shelf life13. In agriculture their uses are: * Preventing damage to crops by destroying insects and weeds * Improving animal welfare by controlling parasitic diseases (e.g. sheep-dip).

  2. Were the Rebecca Riots a justifiable expression of rural discontent?

    On the other hand, the source will not be biased as there is no point to be proven with it, the article is not politically charged. Rev J Evans does uses many farming words and seems to understand the farming techniques at the time.

  1. Is Biological Pest Control Better Than Chemical Control?

    DDT appeared in the lipid of animals throughout all the food webs where primary consumers fed on sprayed crops and where DDT drained from crops into waterways. As DDT is so soluble in lipids, it builds up in the lipid of each animal as it goes up the food chain.

  2. Different methods of pest control and their environmental issues.

    In the 1960s, wildlife biologists were puzzled when the gannet population on Bonaventure Island, Quebec, began to shrink. The shells of the gannets' eggs were too thin to protect the embryos. Only after the eggs had been analysed did the scientists identify the culprit DDT, which had been bioconcentrated through higher levels of the food web.

  1. Is biological pest control better than chemical pest control?

    These pests still destroy all crop yields, by destroying the crop its self and restricting growth in certain ways. When crops are grown they are just like plants in that they compete for mineral ions, water from the soil and light, however when crops are grown using the monoculture method

  2. Is deindustrialisation in the U.K an undesirable process?

    One of the main factors was the fact that the labour force was mainly unskilled and poor training and education schemes led to strikes as the labour force fought for better management and conditions. These 'winters of discontent' led to the perception that Britain's manufacturing industry was in a poor state.
