A comparison of the economic and environmental performances of conventional and organic farming: evidence from financial statements AgEcon
Argiles, Josep M.; Brown, Nestor Duch.
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...

A microbiological survey on tomatoes (Lycopersicon esculentum) marketed in Rio de Janeiro, Brazil. Repositório Alice
PENTEADO, A. L.; CASTRO, M. F. D. P. M. de; PAZIANOTTO, R. A. A..
Abstract: Fresh produce can be a possible source of microbiological contamination. In the past 20 years, several salmonellosis outbreaks due to the consumption of tomato have been reported, mainly in the USA. Organic raw vegetables pose a risk for the transmission of foodborne pathogens since they are often cultivated using manure as a fertilizer. The aim of this study was to conduct a survey of the presence of Salmonella spp, total coliforms and Escherichia coli on the surface of tomatoes from two different production systems. A total of 262 samples of organic and conventional tomatoes were collected from supermarkets and open street markets in the city of Rio de Janeiro, Brazil and analyzed for these microorganisms. To increase the probability of...

Avaliação preliminar de um sistema de irrigação de baixo custo em Assentamentos de Reforma Agrária na Borda Oeste do Pantanal. Repositório Alice
FEIDEN, A.; MALSOLF, T. L.; CONCEIÇÃO, V.; SILVA, A. M. dos S.; BORSATO, A. V.; FEIDEN, A..
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...

EDAPHIC MESOFAUNA COMMUNITY STRUCTURE IN ORGANIC AND CONVENTIONAL MANAGEMENT OF CRANBERRY (Vaccinium sp.) PLANTATIONS: AN AGROECOLOGICAL APPROACH R.C. Suelo Nutr. Veg.
Peredo P,Santiago F; Parada Z,Esperanza; Vega C,Marcela; Barrera S,Claudia P.
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...

Physical soil attributes of Conilon coffee (Coffea canephora) under organic and conventional management systems. Repositório Alice
PARTELLI, F. L.; VALICHESKI, R. R.; VIEIRA, H. D.; GONTIJO, I.; FERREIRA, E. P. de B..
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...

The Comparative Cost and Profit Analysis of Organic and Conventional Farming AgEcon
Urfi, Peter; Hoffmann, Andras; Kormosne-Koch, Krisztina.
The cost-profit relations of organic and conventional farming were examined on the basis of natural and financial data of a large agricultural - company in western Hungary and of economic models characterising private farms in eastern Hungary. The differences in cost structures reflect variable conditions relating to certain crops, but they can be well explained by the differences in the technologies used. According to the production data, in organic farming direct costs per hectare were lower in all of the four examined crops. Even cost per production unit and contribution were more favourable in three of the investigated crops. Regarding the calculation done by economy models, the costs per hectare relating to the two production methods were not...
