Intensification of agriculture

In conclusion, there is very little evidence that even if changes are found in the rhizosphere, the.se changes will remain and actually change the wide biological potential of. soils. A major concern is the lack of reference samples—i.e. what is the natural variance in biodiversity and what are the rates of change as they occur, for example, under intensification of agricultural land u.se. 

It is well known that crop management systems, the quality of the soil and the weathering conditions are just some of the factors used in order to assess production of GHG. Therefore, an understanding of the future environmental impacts of crop production is essential in order to achieve greater crop yields without decreasing the quality of the environment and social welfare. Additionally, Tilman [2] reported that the recent intensification of agriculture, coupled with the prospect of even further intensification in the future, will have major detrimental impacts on the world s ecosystems.

Agricultural production has increased substantially due to the commercialization and intensification of agriculture in developing countries such as Mexico. Identification of... 

Description-. These ions enter the environment in the form of salts. Their presence is due to the extensive use of fertilizers as a result of the intensification of agriculture. As they are plant nutrients, they can lead to eutrophication—the enrichment of water by nutrients, causing an accelerated growth of algae and higher forms of plant life, leading to an undesirable disturbance in the balance of organisms present in the water and in the quality of the water. 

Intensification of agriculture has increased fertilizer use and stock densities, increasing overall nutrient loadings from these diffuse nonpoint sources, At the same time, the growing demand for animal products has led to an increase in facilities for intensive animal production (sometimes known as feedlots"), which are often point sources of contamination,... 

Also, the rapid modernization and intensification of agricultural production in all parts of the world has meant that concerns about the impact of specific pesticides on birds extend beyond national borders. The same toxic pesticide can affect a bird species on its North American breeding grounds as well as on its Latin American wintering and migratory staging grounds. 

Soil pollution mostly results from the intensification of agricultural production and from a general invasion of chemical products in all the fields of human activity. With some generalization, it is possible to consider two... 

Thus, the intensification of agriculture is accompanied by an unusual deterioration of a relationship, which was formerly very simple. The destruction and utilization of traditional agricultural wastes has become a serious ecological problem. 

This rapid expansion did not go unopposed. In the rhetoric used by Khrushchev to disgrace both Malenkov (who especially had favored intensification of agriculture on existing lands) and Molotov, he cited them as part of an anti-party group that opposed the progress exemplified by this project. The key issues seemed to hinge...

Agriculture, like most other industries, passed through a severe depression in the 1930 s, but increasing demand for home produced food in the UK caused a rapid expansion in production in the 1940 s and here we can discern the beginning of the development towards our present intensive agriculture, which is a feature of most developed countries economies today. Taking a simplified view, four developments can be identified which promoted the intensification of agriculture ...
