| While conventional farming systems face serious problems of sustainability, organic agriculture is seen as a more environmentally friendly system since it favours renewable resources, recycles nutrients, uses the environment’s own systems for controlling pests and diseases, sustains ecosystems, protects soils, and reduces pollution. At the same time organic farming promotes animal welfare, the use of natural foodstuffs, product diversity and the avoidance of waste, among other practices. However, the future of organic agriculture will depend on its economic viability and on the determination shown by governments to protect these practices. This paper performs panel regressions with a sample of Catalan farms (Spain) to test the influence of organic farming... |

| Neste trabalho, apresenta-se a avaliação preliminar de um sistema de irrigação que utiliza como aspersor garrafas PET e mangueira preta de polietileno. Como seus materiais são facilmente encontrados e de fácil substituição, sua utilização é indicada para sistemas em transição agroecológica. O sistema foi avaliado em quatro propriedades com o intuito de desenvolver alguns parâmetros técnicos que permitam auxiliar seu dimensionamento, já que até o momento os sistemas são instalados de forma empírica. A pressão estática foi medida com o sistema todo fechado, e a seguir foram acrescentados os aspersores um por um até um total de seis. A cada inclusão, mediu-se a pressão e o raio útil de irrigação do aspersor. A pressão inicial disponível em cada propriedade... |

| The aim of the present study was to determine and compare taxa richness, abundance and diversity of the edaphic mesofauna community between plantations of cranberries (Vaccinium sp.) subjected to organic and conventional management in farms in central-south Chile (37°28'S), as also to evaluate changes produced in their diversity and abundance diversity and abundance, as result of the change from conventional to organic management. In July 2006 two farms were chosen, one with one year under organic management (OM1) and a second one under six years of certified organic management (OM6). Each farm was divided in four quadrants, each one with a surface of 2,500 m . In each quadrant was extracted one sample with six replicas of 188.5 cm³ each. Samples were... |

| Coffea sp. is cultivated in large areas, using both conventional and organic management. However, information about the sustainability of these two management systems is still deficient. The objective of the present study was to evaluate the physical properties of soil cultivated with Conilon coffee (C. canephora) under organic and conventional management. Two areas cultivated with Conilon coffee (under organic and conventional management) and a fragment of Atlantic forest, used as a reference, were selected for the experiment. Soil granulometry, hydraulic conductivity, water retention curve, resistance to penetration, porosity, optimal hydric interval, and other physical characteristics were measured at depths of 0 to 10 and 10 to 20 cm. The data was... |
