The intensification and expansion of modern agriculture is amongst the greatest current to worlswide biodiversity. Over the last quarter of the 20th century, dramatic declines in both range and abundance of many species associated with farmland have been reported in Europe, leading to growing concern over the sustainability of current threats to worldwide biodiversity. Over the last quarter of the 20th century, dramatic declines in both range and abundance of many species associated with farmland have been reported in Europe, leading to growing concern over the sustainability of current intensive farming practices. Pruportedly 'sustainable' farming systems such as organic farming are now seen by many as a potencial solution to this continued loss of biodiversity and receive substantial in the form of subsidy pavmonts through EU and national govermment legislation. This paper assesses the impacts on biodiversity of organic farming, relative to convencional agriculture, through a review, through a review of comparative studies of the two system, in order to determine whether it can deliver on the biodiversity benefits is proponets claim. It identifies a wide range of taxa, including birds and mammals, invertebreates and benefit from organic management through increases in abundance and/or species richness. It also highlights three broad management practices (prohibition/reduced use of chemical pesticides and inorganic fertilisers; sympathetic management of non-cropped habitats; and preservation of mixedfarming) that are largely intrinsic (but not exclusive) to organic farming, and that are particularly beneficial for farmland wildlife. However, the review also draws attention to four key issues: (1) It remains unclear whether a "holistic" whole-farm approach (i.e.organic) provides greater benefits to biodiversity than carefully targeted prescriptions applied to relatively small areas of cropped and/or non-cropped habitats within conventional agriculture (i.e. agri-environment schemes); (2) Many comparative studies encounter methdological problems, limiting their ability to draw quantitative conclusions; (3) Our Knowledge of the impacts of organic farming in pastoral and unpland agriculture is limited; (4) There remains a pressing need for longitudinal, system-level studies order to adress these issues and to fill in the gaps in our knowledge of the impacts of organic farming, before a full aporaisal of its potential role in biodiversity conservation in agroecosystem can be made.

Conteúdo: |
A maioria dos solos da região tem baixo teor de nutrientes minerais. Por isso, as pastagens não contém as quantidades adequadas de elementos minerais essenciais para o crescimento e produção do gado. A correção das deficiências minerais através da suplementação no cocho tem sido utilizada em todo o País. Porém, na região amazônica, os produtores não dispõem de dados seguros que possibilitem equacionar esse problema. Os principais sintomas que indicam deficiência mineral no rebanho são: apetite depravado, redução do apetite, aspecto fraco ou doentio, anomalias dos ossos, fraturas frequentes, anomalias da pele e baixa produção, fertilidade e resistência a doenças. Nas condições da região, os minerais mais importantes na dieta animal são: macronutrientes - fósforo, cálcio, magnésio, enxofre, sódio e cloro; micronutientes - zinco, cobre, cobalto, manganês, iodo e selênio. A forma mais usada para correção das deficiências minerais do gado na região e a suplementação direta no cocho, cujas recomendações práticas são descritas. |
