Ecological Key Elements in the Management Agrosystems

Agroecology has as an objective the understanding of the key elements and processes that regulate the function of agrosystems, for their effective management in harmony with the environment. Plant protection has been focused on the concept of control, mainly utilizing chemical or biological arsenals, and more recently, the biotechnological. The application of ecological criteria in plant protection has allowed the implementation of the biofumigation processes, a technique based on the utilization of gases produced during the biodescomposition of organic matter to manage soilborne phytopathogenic organisms. It is hoped that future improvements in agriculture will consider the increasing worries related to the environment, the conservation of the natural resources, public health, and highlighting attention of the importance of agriculture in the elimination of poverty, as well as its contribution to the development of biofuels.
