2
What is Monoculture
  • In agriculture, "monoculture" describes the
    practice of planting crops with the same patterns
    of growth resulting from genetic similarity.
    Examples include Wheat fields or Apple orchards
    or Grape vineyards. These cultivars have uniform
    growing requirements and habit resulting in
    greater yields on less land because planting,
    maintenance (including pest control) and
    harvesting can be standardized.
  • This standardization results in less waste and
    loss from inefficient harvesting and planting. It
    also is beneficial because a crop can be tailor
    planted for a location that has special problems
    - like soil salt or drought or a short growing
    season.

Diversity
  • A type of agricultural diversity is called
    Polyculture.
  • Polyculture is agriculture using multiple crops
    in the same space, in imitation of the diversity
    of natural ecosystems, and avoiding large stands
    of single crops, or monoculture. It includes crop
    rotation, multi-cropping, intercropping,
    companion planting, beneficial weeds, and alley
    cropping.
  • The diversity of crops avoids the susceptibility
    of monocultures to disease.
  • The greater variety of crops provides habitat for
    more species, increasing local biodiversity. This
    is one example of Reconciliation Ecology, or
    accommodating biodiversity within human
    landscapes.
  • Polyculture is one of the principles of
    permaculture.

Advantages of Monoculture
  • Some of the advantages of monoculture would be
    that when one of the crops is ready to be
    harvested then the likelihood is that the other
    plants would also be ready for harvesting.
  • Also by having all the same types of plan then
    you are able to make an estimate what kind of
    yield you will get overall based on one of the
    crops

5
Disadvantages of Monoculture
  • Some of the disadvantages of monoculture is that
    if there is one of the plants that is affected by
    a disease then the likelihood is that the other
    plants will be affected by this disease.
