agricultural exploitation

• what effect will the removal of hedgerows to make larger Fields have on biodiversity


  it will reduce biodiversity by removing breeding sites, feeding sites and wildlife corridors
• what is meant by monoculture


  Growing a crop with only one species
• what is a disadvantage of monoculture


  an increased chances of pest or disease outbreak
• what effect does monoculture have on biodiversity


  only one habitat reduces the number of different microhabitats that would be available in an area of mixed crops
• how does monoculture affect levels of nutrients in the soil


  it will reduce the concentration of nutrients and soil
• explain how monoculture will reduce the concentration of nutrients in soils

  roots will grow to the same length and extract the same minerals from the same depth of soil
• why can overgrazing lead to soil erosion and desertification


  hooves of cattle compact soil driving out air and preventing water drainage roots cannot penetrate the soil and the grass from grazing cannot grow
