Peat

  1. 1. PEAT Primary source project
  2. 2. WHAT IS PEAT? Peat is an accumulation of partially decayed vegetation or organic matter that is unique to natural areas called peat lands or mires. Peat is also a fossil fuel. Fossil fuels are non renewable sources of energy Peat can be used to cook and heat houses.
  3. 3. WHERE IS PEAT FOUND IN IRELAND? Peat covers a 6th of Ireland and is mainly in the west of Ireland. Peat grows in wet bogs there are two types of bogs Raised bogs and blanket bogs
  4. 4. THE TWO TYPES OF BOGS Raised bogs Blanket bogs
  5. 5. RAISED BOGS Raised bogs are discreet, raised and dome shaped masses of peat in former lakes or shallow depressions in the landscape. They occur throughout the midlands of Ireland. The supply of water and nutrients is from rainfall and the substrate is acid peat soil. It can be up to 12m deep. Raised bogs are identified by low growing, open vegetation dominated by mosses, sedges and heathers, all of which are adapted to waterlogged, acidic and exposed conditions.
  6. 6. BLANKET BOGS Blanket bog form in the mountains and lowlands of the west of Ireland started at the end of the last glaciation, 10,000 years ago. Initially peat formation was confined to shallow lakes and wet hollows. Over time an infilling sequence from open water to fen and acid peat occurred to form the blanket bog habitat we find today. Later, acid peat spread out to form a blanket covering huge areas of poorly drained land. While some spread may have taken place as early as 7,000 years ago, many areas were not engulfed until 4,000 years ago when the climate became wetter. Heavy rainfall caused minerals such as iron to be washed out or leached from the surface layers of the soil, a process known as paludifacation. These were deposited lower down where they formed an impermeable layer known as an iron pan. Water cannot move down through such a layer and the soil surface became waterlogged as a result. Under these conditions the accumulation and spread of peat was made possible.
  7. 7. TECHNOLOGY HAS CHANGED THE RATE BY WHICH PEAT IS EXPLOITED Exploitation of peat lands for fuel has been under way in Ireland for 400 years. Today traditional turf cutting, mechanical turf cutting and industrial peat extraction have accounted for a staggering loss of 47% of the original area of peat lands in Ireland. This represents over half a million hectares of land. It concerns the two types of bogs raised bogs and blanket bogs. If we keep exploiting peat we will run out very soon.
  8. 8. OLD WAY OF PEAT FARMING About 400 years ago when peat farming began and until about 80 years ago used to go out with a slean (a spade for cutting turf) and just went at it. If you were working for a company then the turf would be transported either by cart or train to city's or factories. This all took a time and effort so peat coasted a lot of money to buy and produce.
  9. 9. NEW WAY OF FARMING PEAT Peat is now cut using large machinery to collect tonnes of peat each day Then it is sent to the factory to be processed and turned into briquettes. Not many people have to be employed because machines do most of the work this is call mechanization farming
  10. 10. NEW WAY OF PEAT FARMING
  11. 11. DIFFERENT MACHINERY USED IN THE PRODUCTION OF PEAT. Machinery is very important in the production of peat There are plenty for every job

  16. 16. WHAT WILL HAPPEN TO THE BOGS? Many people want to start to protect bogs from being destroyed from exploitation and visual and normal pollution. The bogs in Ireland make up 51% percent of the bogs in Ireland and are home the artefacts and animals Others believe we should keep using bogs to farm peat because many people like to light fires and many people work in the peat industry in Ireland I think we should be looking into a renewable source of energy such as wind power because Ireland is the windiest country in the E.U
