Copper distribution in chemical soil fractions and relationships with maize crop yield
Abstract Agricultural practices can lead to copper accumulation in soils and at high concentration it can become toxic for plants. One common toxic effect of copper on plants is a decrease of crop yield. Here, we studied 1) the crop yield of maize grown on plots of a soil intentionally enriched with copper sulphate and 2) the possible relationship between the copper concentration in chemical soil ...

Coevolution, agricultural practices and sustainability: some major social and ecological issues
This paper outlines the major social and ecological issues involved in the coevolution of social and ecological systems by initially reviewing relevant aspects of the recent literature relating to economic development and their implications for agricultural development. Coevolutionary qualitative-type models are presented. There has been a failure among advocates of structural adjustment policies ...

Enhancing undergraduate agro-ecological laboratory employment through experiential learning
We piloted an educational model, the Sustainable Agriculture Scholars Program, linking research in organic agriculture to experiential learning activities for summer undergraduate employees in 2007 and 2008. Our objectives were to: (1) further student understanding of sustainable agriculture research, (2) increase student interest in sustainable agriculture careers, and (3) use community service ...

Cropland management techniques for carbon storage
The Kyoto protocol of 1997 recognises cropland management as a carbon sequestration strategy which may help to mitigate climate change. Under the protocol, ratified by the EU in 2002, member states are obliged to reduce the sum of their emissions of greenhouse gases to 5 per cent below their 1990 levels. Appropriate cropland management may help member countries meet the overall EU emissions ...

What is the difference between traditional and modern farming?
Agricultural systems in various parts of the world have evolved due to technological advances and increasing human knowledge. It develops from primitive agriculture, traditional agriculture to modern agriculture. At that time, hunting and gathering activities are familiar techniques for humans. Conventional agriculture started since humans began to settle and cultivate in one location. This ...

The economic impact of climate change on European agriculture A new study has estimated how changes to climate might affect the value of European farmland. Based on data for over 41 000 farms, the results suggest that their economic value could drop by up to 32%, depending on the climate scenario considered- Farms in southern Europe are particularly sensitive to climate change and could ...

Investing in people and evidence for sustainable farming
Evaluation of farming systems, new ideas and learning with practitioners should be part of a transformed agriculture. Food security is difficult to pin down. It can be explained simply as access to enough food. But behind that simplicity lies an interconnected web of factors — from food prices to agricultural practices, nutrition, natural resources, technology, trade and social ...
