Introduction Cost of production The cost of organic dairying Massey University organic /conventional comparison trial Summary Acknowledgements References Appendix Abstract. Organic milk production in the European Union (EU) costs more than conventional production and therefore requires a price premium (15-25%) and an increase in direct payments to ensure the same level of profitability. In Euro...

The organic agriculture represents a promising alternative for the future of European agriculture. It is consistent with the notion of sustainable development set forth already in the 1992 CAP Reform. Despite of increasing importance of organic farming, the research on organic farming is still limited. This scarcity of the research is especially true for New Member States of the enlarged EU. Th...

Project Summary: Recent research on exemplary organic farms in the northeastern U.S.A. identified a vegetable and a grain farm with particularly successful systems. These farms achieve consistently high yields and have low weed, insect and pathogen problems, despite minimal off-farm inputs. The strategy of the proposed project is to demonstrate that these farming systems can be duplicated and c...

Global agricultural and food systems face the challenge of feeding a growing world population in the face of finite and diminishing resources. To guide the redesign of agricultural systems, farmers and policymakers are increasingly turning to agroecology. Organic agriculture has historically integrated agroecological practices within its regulatory framework; however, questions remain as to the...

Emergy Algebra rules may not allow for appropriate accounting of recycled material emergy. The loss of emergy is not permitted using Emergy Algebra rules, but is necessary to address recycling material. It has been proposed to use Dynamic Emergy Accounting so that emergy loss can be factored in when allocating emergy to material recycle pathways. However, systems are often evaluated at steady-s...

The potential of Euglossini bees, especially Euglossa, as biological indicators of organic vs nonorganic coffee farms was studied in Atenas and San Isidro, Alajuela, Costa Rica using 1.8-cineole as lure. Observations were made for three days at each of four farms and complemented with data from a year of observations. Orchid bees were in greater abundance in the organic farms (t-Student test). ...

This paper discusses the effect of commercial alternative and conventional farming systems on soil quality and farm profitability in several countries. Soil quality and farm profitability are two of several indices that measure agricultural sustainability. These studies indicated that the organic and biodynamic farming systems have soils of higher biological, physical, and in many cases chemica...

Growing numbers and increased stocking of marine mussel farms make reliable techniques for environmental effect assessment a priority. Previously, we showed how the color intensity of soft sediment could be used to estimate its acid volatile sulfide (AVS) content, a product of the anaerobic microbial degradation of organic matter deposits. We then proposed to include assessments of the AVS farm...

Organic farming is increasingly recognized as a prototype for sustainable agriculture. Its guidelines ban the use of artificial fertilizers. However, organic farms may import nutrients from conventional farming through material exchanges. In this study, we aimed at estimating the magnitude of these flows through the quantification of nitrogen, phosphorus and potassium inflows from conventional ...
