Utjecaj suvremene industrije, poljoprivredne proizvodnje i morala na zagadivanje čovjekove okoline Organic Eprints
Znaor, Darko.
The paper provides an overview on major environmental problems caused by farming practices (and to a degree by industry). It discuses various problems related to declining soil fertility, use of pesticides, accumulation of heavy metals in agricultural soils, etc. Finally, it questions validity and enforcement of some environmental and agricultural legislation and argues that the way out is in adopting organic and bio-dynamic farming.

Diagnóstico da agricultura orgânica no estado do Rio de Janeiro e propostas para sua difusão. Organic Eprints
Assis, Renato Linhares de.
A agricultura organica tem sido citada recentemente por um numero cada vez maior de pessoas como uma opção viavel ao modelo agricola atual, o qual tem provocado sérios problemas ambientais e para saude humana. No entanto, pouco se tem observado como se da o processo de adocao deste sistema de producao por agricultores e consumidores para que se possa difundi-lo cada vez mais. A partir de entrevistas com produtores organicos fluminenses, procedeu-se a uma analise do processo de adocao deste tipo de agricultura e das dificuldades para sua difusao no Estado do Rio de Janeiro. Verificou-se que os agricultores entrevistados, possuidores de forte posicionamento ideologico, funcionam como importante vanguarda no processo de difusao, o qual, para ser incrementado...

Effect of three farming systems (bio-dynamic, bio-organic, conventional) on yield and quality of beetroot (Beta vulgaris L. var. esculenta L.) in a seven year crop rotation Organic Eprints
Mäder, P.; Pfiffner, L.; Niggli, U.; Balzer, U.; Balzer, F.; Plochberger, A.; Velimirov, A.; Besson, J.-M..
In a long-term field trial in Therwil, Switzerland, the bio-dynamic, bio-organic and conventional farming systems were compared (DOC trial). The present paper focuses on long-term yield development and on product quality of beetroot. Due to the favourable climate and soil, beetroot yields were generally high. The yield of beetroot in both biological systems was about 75 % that of the conventional system, but the input of nitrogen and potassium was about 60 % lower.

Análise da eficiência técnica em zonas agroecológicas brasileiras. Organic Eprints
Aguiar, Jozeneida Lúcia Pimenta de.
Sabe-se que a agricultura e uma atividade que depende, basicamente, das potencialidades do meio ambiente fisico natural onde ela se desenvolve. No entanto, os processos tecnologicos associados a disponibilidade dos fatores capital e mao-de-obra sao capazes de influenciar fortemente os niveis de produtividade e de producao a serem obtidos em dado meio fisico agroeco1ogico. Dessa forma, o conhecimento da eficiencia no uso dos fatores em zonas agroecologicas, similares quanto a sua estrutura de producao, pode indicar o seu uso mais racional. Pretende-se, neste trabalho, estimar a eficiencia/ ineficiencia tecnica no uso dos fatores de producao em zonas agroecologicas brasileiras. Para tal, especificamente procurou-se: agrupar e caracterizar as zonas...

Energy use in crop production on danish mixed farms: Systems modelling of data from farm studies Organic Eprints
Halberg, Niels; Kristensen, Erik Steen; Refsgaard, Karen.
The problems of balancing agricultural production methods against environmental concern cannot be solved by focusing on single activities of livestock farming and experimental knowledge alone because of interactions between herds and crops and between the production system and the manager. An alternative method based on studies in private farms is proposed to evaluate the effects of the production intensity on pollution and resource efficiency. Energy use and crop yield in gram and grass-clover crops registered on conventional and organic mixed dairy farms were analyzed in order to facilitate modelization of energy efficiency in different production systems on different danish soil types. The energy efficiency was higher in organic crops on all soil types...

Ecological agriculture- a way towards sustainable agricultural practice Organic Eprints
Znaor, Darko; Bošnjaković, Branko.
Today, and especially in the years to come, agriculture, as well as all other human activities, will have to pay much more attention to their environmental impacts. In other words, it is expected that in the near future only technologies which care about environmental aspects will be promoted and accepted by policy makers, scientists, consumers, and society in general. This is not surprising since the environmental problems are among the most urgent ones our civilization will have to tackle and solve. This demand for more careful stewardship of environment is also acknowledged by philosophy of sustainable development - a widely recognized concept and necessity of future development. Although established at the very beginning of this century, ecological...

Conversion to Organic Milk Production (OF0103) Organic Eprints
Haggar, Roger; Padel, Susanne.
This is the final report from the Defra project OF0103 In the UK fewer than 50 dairy farms were registered as organic in June 1995. The slow increase of farmers willing to convert to organic milk production was seen as one impediment for development of the organic milk market. The overall objective of this joint 3-year project was to monitor the physical, environmental and financial implications of conversion to organic milk production on a research farm (Ty Gwyn) and ten commercial farms in southwest England and Wales, in order to provide policy makers and farmers with more information about the consequences of conversion. Although the size of the sample is comparably small it represents about 20% of all organic dairy farms in the UK and an even larger...

Dairy farm production strategy and nitrogen surplus Organic Eprints
Halberg, Niels; Jensen, Carsten Hvelplund.
Via public legislation minimum standards for the utilization of manure have been introduced as an obligatory part of fertilization planning. And many Danish livestock farmers have improved the utilization of manure during the last five to ten years. There is, however, still not consensus concerning the question of whether the results are sufficient to reduce the loss of nitrogen to ground water and the Danish marine environment to acceptable levels. In an analysis of 30 dairy farms Halberg et al. (1995) showed a variation in N surplus between 88 and 387 kg/ha depending on stocking rate and management. At ca. 1.4 livestock units1) per ha there was a difference between 250 and 116kg N/ha farm level surplus. It was concluded that differences between farms...

As perspectivas da pequena produção familiar na agricultura. Organic Eprints
Ciprandi, Olivio; Neto, João Fert.
As perspectivas da pequena produção familiar na agricultura constitui um tema controvertido na sociologia e na economia rural. A modernização da agricultura alterou suas relações com o restante da economia. As mudanças na base técnica e as políticas agrícolas determinaram a necessidade de crescimento das escalas mínimas viáveis do ponto de vista técnico e econômico, promovendo um processo de seleção e exclusão entre os pequenos produtores rurais, sem no entanto implicar na eliminação da pequena produção familiar.

Carbon Source Utilization by Microbial Communities in Soils under Organic and Conventional Farming Practice Organic Eprints
Fliessbach, Dr. Andreas; Mäder, Dr. Paul.
In a long-term field trial in which organic and conventional agricultural systems were compared since 1978 we analyzed soil microbial biomass, microbial activity and substrate utilization patterns by the Biolog GN microplates. Microbial biomass and the Cmic -to-Corg ratio was distinctly higher in organic plots whilst the metabolic quotient qCO2 as an indicator of the energy requirement of soil microorganisms was lower. Substrate utilization profiles were affected by the different lon-term treatments, but also indicated differences of short-term effects like crop and soil management steps.

Organic Agriculture in Denmark - Economic Implications of a Widespread Change Organic Eprints
Wynen, Els.
To assess the effects of a hypothetical widespread adoption of organic practices in Denmark, a four-region, partial equilibrium model of the Danish agricultural sector, the Danish Organic Agriculture Project (DOAP), was constructed for the Danish Institute of Agricultural and Fisheries Economics (SJFI). DOAP contains 3 farm sectors, crops, dairy and pigs, and permits farmers to have up to 16 cropping activities. Detailed costs of production are modelled in each sector and region. DOAP contains two production structures, one conventional and one organic, currently representing less than 2 per cent of Danish farms. By exogenously specifying the number of farms using each method of production, the impact of a switch to organic methods on national outputs and...

Comparative review of the effects of organic farming on biodiversity (OF0149) Organic Eprints
Gardner, Sarah M.; Brown, R. W.; R & D Associates,.
This is the final report of Defra project OF0149 1. The report reviews the impact of different farming regimes and makes a comparative study of their influence on the biodiversity of arable farmland. 2. Within this review, the evaluation of impacts on biodiversity focuses on species and habitats, and includes both the number, abundance and activity of species (section 1.3). 3. Five farming regimes are defined and discussed, namely Conventional Arable, Conventional Mixed Lowland, Organic and two integrated production regimes - LEAF (Linking Environment and Farming) and IFS-Experimental regimes The main differences between the regimes in relation to the use of external inputs and other agricultural practices are discussed. The review draws on both...
