Soil management for agro-ecosystems

Moscow University Soil Science Bulletin, 2011
Several problems of soil biotechnology and their relation with global ecological problems are considered. An analysis of the principal opportunities for soil biota management shows that scientific progress in this field is a necessary but insufficient condition for the solution of these global problems.

Agro-ecosystems in future society

Agro-Ecosystems, 1974
Abstract The transformation, through a technological revolution, of traditional peasant farming into a modern technology and a specialised, market-oriented production process has contributed to a rapid deterioration of the natural environment. The development of well-balanced agro-ecosystems, which respond to various societal needs, requires global ...

Emergence of Research on Agro-Ecosystems

Annual Review of Ecology and Systematics, 1977
Ecosystem research using a systems approach has been under way in ecology for about fifteen years, mostly as studies of energy flow and nutrient dynamics. During this time the methods of ecosystem analysis have been applied to a few lightly managed natural resource systems such as fisheries, forestry, and rangelands (30).

A comparative study of the Egyptian agro-ecosystem

Agro-Ecosystems, 1979
Abstract Details are presented of the various inputs into the Egyptian agro-ecosystem together with information on its food production. Egyptian agriculture is shown to be very productive and efficient in its exploitation of solar and fossil fuel energy inputs compared with the other national systems for which information is available, but less so in

Genotoxic Agents in the Agro-Ecosystem Chairman’s Comments

1982
In our agro-ecosystem, there are at least four classes of genotoxic agents that have been detected and characterized: 1. Genotoxic metabolites produced by plants and fungi. 2. Genotoxic heavy metal salts found in the soil. 3. Genotoxic man-made chemicals used as pesticides and other agricultural chemicals.

Toxic Agents in the Agro-Ecosystem Chairman’s Comments

1982
As we begin the session concerned with Toxic Agents In the Agro-Ecosystem, it seems proper to consider additional ways in which a chemical may interact with its target. While the first portion of this session dealt principally with the direct effects of mycotoxins acting on receptor systems, the following papers will offer possibilities wherein ...
