At the present time, soil carbon sequestration is of paramount importance to address the imminent threat of increased atmospheric carbon dioxide, which is looming large on the very survival and existence of the biome. The quantum of all carbon everywhere in the globe is same and fixed. It exists to the tune of 800 Pg in the atmosphere, 1700 Pg in terrestrial and 38000 Pg in aquatic ecosystem. E...

26.06.2008. Research The cultivation of genetically modified maize has caused a drastic reduction in organic cultivation of this grain and is making their coexistence practically impossible. This is the main conclusion reached in one of the first field studies in Europe carried out by a researcher of the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona,...

Organic production and consumption provide a delineated food system that can be explored for its potential contribution to sustainable diets. While organic agriculture improves the sustainability performance on the production side, critical reflections are made on how organic consumption patterns, understood as the practice of people consuming significant amounts of organic produce, may also be...

in this research, the effect of using vermicompost on growth rate, fertility and characteristics oftomatoes has been studied. four vermicompost: soil mixture were supplied with ratios of 1:1, 1:2, 1:3, and 1:4 and also four different beds were provided. total of 24 small globe tomato plants were tested and in each bed combination, six tomato plants were embedded. rate of growth and yielding of ...

Urban agriculture has been recently highlighted with the increased importance for recreation in modern society; however, soil quality and public health may not be guaranteed because of continuous exposure to various pollutants. The objective of this study was to evaluate the soil quality of urban agriculture by soil microbial assessments. Two independent variables, organic and inorganic fertili...

The article’s objective is to analyze a process of technological innovation incorporation in the realm of organic agriculture which, as per legal and conceptual definition, should take into consideration the economic, social and environmental aspects according to the proposals of sustainable development. This article presents the results of a case study carried out at Native Alimentos Orgânicos...

Introduction With the implementation of consistent federal standards for products marketed as “organic” in October 2002 (USDA/AMS, 2002), organic production and consumption is expected to increase beyond current organic sales of $10 billion in 2001 (OTA, 2002). In 1999, Iowa farmers reported 150,000 acres of organic production to the Iowa Department of Agriculture and Land Stewardship survey (I...
