Biosphere basis for improving agriculture productivity
The most vulnerable is the soil cover of the earth, as a core component of all processes in the biosphere. The agricultural sector, in fact, is the process of using agrocenoses the benefit of humanity. Meanwhile, it is now agrocenosis occupy almost half of ecological landscapes and geological influence on the biosphere processes significantly exceed the role of natural plant populations. This is especially important due to the increase in areas used by mankind for their needs. In this area, people impacts on ecosystems, rejecting part of matter and energy in the cycle ensuring human power, disrupting biotic turnover, which will inevitably impact on the environment. As a rule, it becomes unfavorable, not only for the biosphere, but also to human life. However, secondary biogeocoenoses arising in place of indigenous human impact is not always flawed. Indirectly, the level of adaptation of agricultural technologies to the biosphere can be estimated by using the concepts of biotechnical coefficient (BEC) and antropogen-energy ratio (AER). In English, such studies are called "input-output analysis of energy use in agriculture"
