| O presente trabalho avalia aspectos de ordem social, econômica e ambiental advindos das práticas dos agricultores familiares da APROFAM (Associação dos Produtores e Produtoras Agroecológicas de Mossoró), que comercializam semanalmente sua produção na Feira Agroecológica, de modo a analisar como proporcionam o desenvolvimento sustentável da agricultura de base familiar. Para tanto, foram realizadas entrevistas dialogadas com seis desses produtores. Os dados foram obtidos através de visita in loco, registro fotográfico e levantamento de dados qualitativos e quantitativos no período de janeiro a março de 2012. A criação da Feira possibilitou o acesso ao mercado local, organização por parte dos produtores para adquirir a certificação participativa, produção... |

| Este texto teórico aborda os desafios de a Agroecologia se consolidar como um campo científico, visto que muitos pesquisadores envolvidos em sua temática requerem para ela o status de Ciência, ao mesmo tempo em que a sua postura epistemológica questiona severamente os paradigmas vigentes no campo científico. Aqui se defende que a Agroecologia pertence também ao campo científico, não negando que ela possa pertencer a outros campos, e que esse pertencimento é estratégico para evitar o seu desvirtuamento. A partir disso remete ao funcionamento dos campos científicos na busca de elementos que auxiliem a Agroecologia a superar as críticas, marginalizações e preconceitos de uma nova ciência que deseja estabelecer os seus novos paradigmas. |

| O artigo analisa as estratégias de 03 redes de cooperativas que trabalham com leite no Território Oeste de Santa Catarina, verificando sua aproximação com princípios e práticas agroecológicas. Foram estudadas as redes Aurora, Terra Viva e Ascooper, analisando documentos e realizando entrevistas com suas principais lideranças. A agricultura familiar está na base organizacional das 03 redes e ela adotou a produção de pastagem como a principal forma de alimentação dos animais, o que representa uma inovação coletiva no território, ocorrida de forma difusa, sem liderança de nenhum ator social específico. Além da produção à pasto, a Terra Viva e a Ascooper avançaram com a fitoterapia e a homeopatia na sanidade dos animais, mostrando maior ênfase na construção de... |

| O presente artigo é uma revisão de literatura elaborada a partir de uma olhar sobre os reflexos da política de modernização agrária na Amazônia no sistema tradicional de uso da terra de agricultores familiares da comunidade São João onde foram implantados sistemas agroflorestais (SAF´s) através do projeto Raízes da Terra. A metodologia utilizada mesclou abordagens quantitativas e qualitativas com a realização de entrevistas, questionários, observações e revisão de literatura em um estudo de caso constituído por 15 famílias de agricultores. As principais conclusões mostram que a implantação de SAF´s foi uma proposta idealizada e organizada por agentes externos à comunidade São João e conhecedores da realidade local, que através do projeto Raízes da Terra,... |

| This year marks a centenary of the synthetic fertilizer industry. German chemists, Fritz Haber and Carl Bosch, in 1909 demonstrated their industrial process for the manufacture of ammonia. The achievement won them accolades including Nobel Prizes. The output of their Haber-Bosch process can be used for either peace or war, agriculture or munitions, and the rapid adoption by Germany of this industrial process is credited with prolonging WW1. Most of the synthetic nitrogenous fertilizer of the past century, and right up to the present, has been manufactured using the Haber-Bosch process. The use of synthetic fertilizers has led to significant negative environmental outcomes. Rudolf Steiner was an early voice against chemical agriculture. Steiner's... |

| The objective of this article is to determine the economic performance of organic farms compared with conventional farms. The analysis included a set of farms the concentration of which is in natural and climatic conditions typical for this type of farming high. The outputs may be therefore considered representative and generalised. In order to determine the performance of these farms, their production basis was first assessed by using the indicators of available assets and assets coverage resources. Consequently, their efficiency was assessed based on the profit. For the purposes of comparison, the profit was (in various forms) converted to a hectare of agricultural land. The economic results were also compared with the average level achieved in the EU.... |

| Background: It has been questioned if the old native Norwegian sheep breed, Old Norse Sheep (also called Norwegian Feral Sheep), normally distributed on coastal areas where ticks are abundant, is more protected against tick-borne infections than other Norwegian breeds due to a continuously high selection pressure on pasture. The aim of the present study was to test this hypothesis in an experimental infection study. Methods: Five-months-old lambs of two Norwegian sheep breeds, Norwegian White (NW) sheep and Old Norse (ON) sheep, were experimentally infected with a 16S rRNA genetic variant of Anaplasma phagocytophilum (similar to GenBank accession number M73220). The experiment was repeated for two subsequent years, 2008 and 2009, with the use of 16... |

| Increased demand for certified organic products has led to an increase in the number of certified organic farms in developing countries. Knowledge of farmer nutrient management practices on certified organic farms in developing countries is limited. Thus, the aim of this study was to investigate the impact of the adoption of certified organic agriculture on farm nutrient flows and nutrient budgets, and evaluate to which degree organic farms comply with organic principles relating to nutrient management. The study is based on five case studies of different types of certified organic farming systems in Brazil, Egypt and China. Farm nutrient flows and nutrient budgets for nitrogen, phosphorous and potassium were created for each farm. Four of the five... |

| Nitrate leaching losses from intensively managed monoculture grass and grass-clover pastures were measured during 1994-96 at a long-term experimental farm in south-west Scotland. Field-size lysimeter plots were established in 1993 on the existing pastures on a silty clay loam non-calcareous gley. No fertilizer-N was applied to the grass-clover, while the monoculture grass was fertilized with c.240 kg N ha-1 year-1, but both swards received 2-3 cattle slurry applications annually (120-390 kg total N ha-1 year-1). The pastures supported 2-3 cuts for silage conservation, and were grazed by dairy cattle and stocked with sheep during the winter months. Initially, leachate nitrate concentrations from the fertilized grass were considerably larger than those... |

| Tomato (Lycopersicon esculentum Mill.) is one of the most popular and versatile vegetables in the world, and organic production with a high yield and desirable quality is a target of many producers. The effect of four different fertilizers (chemical, municipal solid waste compost, cattle manure, and spent mushroom compost) on four commercial tomato cultivars (Redstone, Flat, Peto Pride and Chief) was assessed in this research. The highest yield was obtained with the Chief cultivar when fertilized with chemical fertilizer and the lowest value was obtained with Peto Pride fertilized with 20 tonnes per hectare (t/ha) of cow manure. The difference between the two classes of fertilizers (organic and chemical) was not very high so that organic fertilizers are... |

| In a historical sense, current organic farming is an old-new alternative under changed world conditions. Organic dairying (O) is an alternative of friendly use of the environment in time of presupposed global climate changes. Potential impact of organic farming on raw cow-milk quality, composition and properties, as conpared to conventional milk production (C), were evaluatedin this paper on the basis of selectedm ilk indicators (MIs). Total solids, whey volume, pH of milk fermentation ability (FAM-pH), FAM streptococci, FAM noble lactic acid bacteria, I and Cu were higher in C milk (P<0.05). The alcohol stability (AS), titration acidity, curd firmness (CF), FAM titration acidity (FAM-T), Ca, P, Mg, K and Fe were higher in O milk (P<0.05).... |

| Organic farming and improvements to agricultural sustainability are often seen as synonymous. However, an extensive European review demonstrated that in practice this is not always true. This study aims to compare the status of soil and water properties between separate fields managed in either an organic or a conventional manner. Soil samples were collected from 16 pairs of farms, throughout England, with both arable and grass fields within each pair on similar soil type. Chemical (nutrients, pesticides, herbicides) and physical (aggregate stability, field capacity, shear strength, soil organic matter, infiltration rates) soil properties were measured in four main soil texture classes in organic and conventional fields. The physical soil properties varied... |
