Rapid emergence of pathogens in agro-ecosystems: global threats to agricultural sustainability and food security.
Agricultural ecosystems are composed of genetically depauperate populations of crop plants grown at a high density and over large spatial scales, with the regional composition of crop species changing little from year to year. These environments are highly conducive for the emergence and dissemination of pathogens. The uniform host populations facilitate the specialization of pathogens to parti...
متن کاملControl of food and agro product contamination in Bulgaria.
The ban of organochlorine pesticides in Bulgaria (1969) has led to their significant drop below the maximum residue limits. The climate and the imperfect storage facilities benefit the production of Fusarium toxins desoxynivalenol (folytoxin), zearalenon (F-2), T-2, ochratoxin A and aflatoxins in grain products, M1 in milk products, and patulin in apple juices and nectars. Heavy metals are foun...

متن کاملPatterns of input–output relations in agro-ecosystems
Two different patterns in input–output relations can be distinguished in agricultural production. For the first, yields are obtained at zero rates of certain external inputs, such as in wheat growing, or dairying based on grazing. For a second type of input–output relation, inputs are required before any yield can be obtained, such as in irrigation schemes in desert areas, or industrial product...
متن کاملEcosystems, Sustainability, and Grassland Management
The long-term sustainability of modern agriculture is examined in an ecological context. As an aid to defining agriculture, animal agriculture, and sustainable agriculture, a broad overview of the structural and functional aspects of ecosystems is presented. The longterm sustainability of two corn production systems and four beef cattle production systems is then examined relative to energy out...
