This study aimed to compare conventional livestock production systems in relation to other forms that implement ecological production, evaluating environmental variables (in water: nitrite, nitrate, phosphate, pH and availability of oxygen using photometrics methods and Winkler modified method. In soils: counts of bacteria and fungi using MPN method, and physicochemical properties. In meadows: Prairie composition, quantity and density of arthropods), productive variables (in forages: biomass estimation using the methodology by Campbell and Arnold, nutritional quality using bromatology methods, in animals: milk production, weight gain, and carrying capacity), and economic variables (Fertilization cost and control ecto-endo parasites cost) in 6 farms... |

Recently a revised version of the German standard method for humus balancing according to VDLUFA has been published. In contrast to the preceeding version, the method now shall be applicable not only in conventional, but also organic farming systems. In this contribution, we try to define the scope of the three levels of organic matter demand parameters for crops applied in the method, as an applicable definition is missing in the VDLUFA method description. We do so by calculating crop uptake of mineralized humus-N from the balance parameters, and by linking N uptake to yield levels of crops. Further, we calculate humus balances for farming system treatments in the Organic Arable Farming Experiment Gladbacherhof (Villmar,Germany) and test the ability of... |

This project is supported by the European Commission under the 6th framework Program (Project number SSPE-CT-2003-501997). It is a Specific Targeted Research Project (STREP) for scientific support of policies with a budget of 2.7 million Euros. The project has started January 2003 and will be finished in March 2007. The aim of this project: The project will support Community policies for sustainable agriculture by providing a harmonised European approach for indicators of the overall risk of pesticides. It will integrate European scientific expertise on the use, emissions and environmental fate of pesticides and their impact on agro-ecosystems and human health. The indicators will provide new and powerful assessment tools for monitoring and managing... |

Life Cycle Assessments (LCA) of food and agriculture generally include potential effects on global warming, eutrophication, ecotoxocity and acidification some of which again affect biodiversity. However, LCA most often does not include specific indicators of the product’s or agricultural system’s impact (negative or positive) on biodiversity. Using LCA methodology on agricultural products makes it highly relevant to assess the impacts of land use. Some LCA’s include a simple category of land use. This is sometimes interpreted as “nature occupation”. However, if this is the only impact category addressing land use related biodiversity, the LCA cannot distinguish between different forms of agricultural systems, which may differ in their biodiversity impact... |

In low-input and organic systems, nutrient management is key to ensuring the short-term productivity and the longer-term sustainability of the farming system. Farm-gate nutrient budgets/balances calculate the inputs of nutrients to, and outputs from a system. Hence, they can be used to assess the nutrient use efficiency. Nutrient balances of 69 organic and low-input dairy farms in seven European countries were carried out using a sustainability assessment tool. The tool assesses each individual farm against a number of indicators. Part of the assessment of nutrient management is the calculation of an N,P,K budget, based on physical inputs and outputs for each enterprise. The results show considerable variation in the calculated N,P,K balances. The paper... |

In 2010, the Republic Act 10068 or Organic Agriculture Act (OAA) was signed to promote and further develop the practice of organic agriculture in the Philippines. The Bureau of Soils and Water Management (BSWM) as one of the implementing agencies of the OAA and National Organic Agriculture Program (NOAP) has a critical role in implementing programs and projects that would provide support services to improve the physical, chemical and biological characteristics of soil and conduct research and development studies on this concern. Recognizing that there is a need to study the different soil management practices in third party certified organic farms, which have received the national award as outstanding organic farm from 20011-2013, the BSWM documented... |

The aims of this study were to determine the phytotoxicity of stored rapeseed (Brassica rapa) oil (RSO) and rapeseed oil methyl ester (RME) after "spill like" contamination on the growth of barley (Hordeum vulgare) and the biodegradability of these substances in OECD 301F test conditions and in ground water. Rapeseed oil and rapeseed oil methyl ester were both stored for a period of time and their fuel characteristics (e.g. acid number) had changed from those set by the fuel standards and are considered to have an effect on its biodegradation. The phytotoxicity was tested using two different types of barley cultivars: ‘Saana’ and ‘Vilde’. The phytotoxic effect on the barley varieties was determined, after the growth season, by measuring the total biomass... |

Euroopas tuleb hinnanguliselt umbes 30% kogu eratarbimise keskkonnamõjudest toidusektorist, kuid näiteks veekogude eutrofeerumisse panustab toidutootmine isegi 60% ulatuses (Tukker jt., 2006). Jätkusuutliku toidutootmise arendamine, mis vähendaks oluliselt keskkonnakoormust, on EL-i strateegiline eesmärk. Keskkonnasõbralike tehnoloogiate valikul tuleb mõõta nende mõjusid läbi olelusringi ehk võtta arvesse ka vajalike sisendite tootmise keskkonnamõjusid. Vastasel korral võib soovitav keskkonnakoormust vähendav muudatus ühes tootmise etapis põhjustada hoopis suuremaid keskkonnamõjusid teises etapis. Artikkel annab lühiülevaate mahepõllumajanduse keskkonnamõjudest läbi olelusringi võrreldes tavapõllumajandusega. |

No presente trabalho, apresentaremos a maricultura, vista como tecnologia de produção de alimento de origem marinha e possível alternativa para contribuir com a alimentação e superação da pobreza de grande parte da população, e suas implicações ambientais. Nós procuramos apresentar as diferentes tecnologias atualmente empregadas, bem como as alterações que a atividade pode causar no meio ambiente. Foi observado que a quantidade de impactos ambientais negativos se sobressai aos impactos positivos se a produção não for realizada de forma adequada e que os impactos ambientais positivos são benéficos dependendo do ponto de vista. Os estudos na área de maricultura são recentes, principalmente no Brasil. Assim a identificação de seus problemas focada nas... |
