Agrocenosis differences, signs and goals | Examples of agrocenosis

The ecosystem is the interaction of a living and inanimate nature, which consists of living organisms and their habitat. The environmental system is a largescale balance and connection, which allows you to maintain a population of species of living creatures. Nowadays, there are natural and anthropogenic ecosystems. The differences between them are that the first is created by the forces of nature, and the second with the help of man.

The value of agricultural value

Agrocenosis is an ecosystem created by human hands in order to obtain agricultural crops, animals and mushrooms. Agrocenosis is also called agroecosystem. Examples of agrocenosis are:

  • apple and other gardens;
  • fields of corn and sunflower;
  • pastures of cows and sheep;
  • vineyards;
  • Garden.
  • A person, due to satisfying his needs and increasing the population, has recently been forced to change and destroy natural ecosystems. In order to rationalize and increase the volume of crop of agricultural crops, agroecosystems are created by people. Nowadays, 10% of all available land is occupied by land for growing agricultural crops, and 20% pastures.

    The difference between natural ecosystems and agrocenosis

    The main differences in agricultural focus and natural ecosystems are:

  • Artificially created cultures cannot compete in the fight against wild plants and animals;
  • Agroecosystems are not adapted to selfhealing, and completely depend on a person and without him quickly weaken and die;
  • A large number of plants and animals of the same species in the agroecosystem contribute to the largescale development of viruses, bacteria and harmful insects;
  • In nature, there is much more variety of species, unlike cultures bred by man.
  • Artificially created agricultural areas should be under the full control of a person. The disadvantage of agricultural focus is to increase the populations of pests and fungi, which not only harm the crop, but can also worsen the state of the environment. The number of cultural population in agricultural protrusion increases only with the help of use:

  • weed fighting and pests;
  • irrigation of arid lands;
  • drying of waterlogged land;
  • replacement of varieties of cultures;
  • Fertilizers with organic and minerals.
  • In the process of creating an agroecosystem, a person built fully artificial stages of ecosystem development. Soil land reclamation is very popular an extensive complex of measures aimed at improving natural conditions in order to get the highest possible level of crop. Only the correct scientific approach, control of the state of the soil, moisture level and mineral fertilizers can increase the productivity of agriculture in comparison with the natural ecosystem.

    Negative consequences of agriculture

    It is important for humanity to support the balance of agro- and natural ecosystems. People create agroecosystems to increase the number of food and use them for the food industry. However, the creation of artificial agroecosystems require additional territories, so people often cut down the forests, set up the earth and thereby destroy existing natural ecosystems. This violates the balance of wild and cultural species of animals and plants.

    The second negative role is played by pesticides that are often used to combat insect pests on agroecosystems. These chemicals through water, air and insect pests fall into natural ecosystems and pollute them. In addition, excessive use of fertilizers for agroecosystems causes pollution of water bodies and groundwater.
