Agrophotovoltaik – Auswirkungen auf Mikroklima und landwirtschaftliche Erträge Organic Eprints
Weselek, Axel; Ehmann, Andrea; Zikeli, Sabine; Lewandowski, Iris; Högy, Petra.
Agrophotovoltaik (APV) ermöglicht die simultane Produktion von Nahrungsmitteln und Strom auf derselben Fläche, indem die Solarmodule etwa sechs Meter über der landwirtschaftlichen Fläche montiert sind. In der vorliegenden Studie wurden die Auswirkungen von APV auf die ökologische Produktion von Kleegras und Winterweizen sowie verschiedene mikroklimatische Parameter untersucht. Infolge veränderter mikroklimatischer Bedingungen und einer Reduktion der photosynthetisch aktiven Strahlung, kam es zu einer Abnahme der landwirtschaftlichen Erträge.

Bioethanol from Germinated Grains. Organic Eprints
Thomsen, MH; Tajoacha, N; Wu, C; Hovgaard, S; Houmøller, LP; Holm-Nielsen, JB; Thomsen, AB.
The most well-known way to produce bioethanol is by the enzymatic hydrolysis and fermentation of starch. In a new project “BioConcens” (2007) sponsored by DARCOF (DAnish Research Center for Organic Food and farming) one aim is to develop a combined ethanol and biogas production for use in organic farming using starch containing biomass. Natural enzymes from cereals will be used for hydrolysis of starch to glucose in accordance with technology in brewing technology. Commercial enzymes are often produced from gene-modified organisms and will therefore not be used in the suggested organic context or process. A preliminary study was performed in which grains of wheat, rye, and barley were germinated using traditional methods applied in malting for beer...

Biogas on-farm: energy and material flow Organic Eprints
Schäfer, Winfried.
Objectives: European countries are committed to reduce CO2 emission originating from fossil fuels. On-farm produced biogas may replace energy produced from fossil fuels and so contribute to achieve the target. Up to now only in Germany a greater number of on-farm biogas plants has been established. The data of these plants can be used to evaluate cost and benefit of on-farm biogas production in other European countries. This paper concerns the following questions: Which parameters of biogas plant construction and operation have an influence on profit and sustainability of biogas production on-farm? Hypothesis: A biogas plant integrated within a self-contained farm organism is economically more competitive and more sustainable than an industrial...

Biomass energy in organic farming - the potential role of short rotattion coppice Organic Eprints
Jørgensen, Uffe; Dalgaard, Tommy; Kristensen, Erik Steen.
One of the aims of organic farming is to “reduce the use of non-renewable resources (e.g. fossil fuels) to a minimum”. So far, however, only very little progress has been made to introduce renewable energy in organic farming. This paper presents energy balances of Danish organic farming compared with energy balances of conventional farming. In general, the conversion to organic farming leads to a lower energy use (approximately 10% per unit of product). But the production of energy in organic farming is very low compared with the extensive utilisation of straw from conventional farming in Denmark (energy content of straw used for energy production was equivalent to 18% of total energy input in Danish agriculture in 1996). Biomass is a key energy carrier...

Characterisation of most relevant feedstock for biogas and bioethanol production in organic farming Organic Eprints
Oleskowicz-Popiel, Piotr; Thomsen, Mette Hedegaard; Nielsen, Henrik Bangsø; Schmidt, Jens Ejbye; Thomsen, Anne Belinda.
Bioenergy production from local bioresources has a great potential. It is important to reduce dependency on fossil fuels and decrease green house gas emission in organic agriculture (OA). Both biogas and bioethanol can be produced in OA and significantly contribute to the sustainability of organic farms. Soil fertility is the basis for OA: it has been of concern that the fertility might decline if most of the organic residues were converted into energy and only effluent from anaerobic digestion process was recycled. However, by intelligent management of organic residues and crop rotation it is possible to avoid decrease of soil fertility and at the same time produce renewable energy. The presented study is part of the BioConcens project...

Concentrations of soil potassium after long-term organic dairy production Organic Eprints
Løes, Anne-Kristin; Øgaard, Anne Falk.
On five long-term organic dairy farms aiming at self-sufficiency with nutrients, soil concentrations of ammonium-acetate lactate extractable potassium (K-AL) and acid-soluble K was measured twice in topsoil (0-20 cm) and subsoil (20-40 cm) over periods of 6-14 years. Organic management had occurred for >9 years at the second sampling. On average there were most probably field level K-deficits. Even so, topsoil K-AL concentrations were medium high (65-155 mg K kg–1 soil), and did not decrease during the study period. However, for three farms, topsoil K-AL was approaching a minimum level determined by soil texture, where further decrease is slow. Subsoil K-AL concentrations were generally low (<65). The soils were mostly light-textured, and reserves of...

Conclusions Organic Eprints
Kahiluoto, Helena; Vesala, Kari.
There is good potential for sustainable localisation and recycling in rural food systems around the Baltic Sea. Localisation and recycling enhance sustainability in its ecological, economic and social dimensions. A sustainable way of localisation and recycling would be local recycling between farms and from the demand chain.

Eating Oil Organic Eprints
Woodward, Lawrence; Jones, Andy.
The food system is now even more based on cheap crude oil. Every time we eat, we are all essentially ‘eating oil’. Virtually all of the processes in the modern food system are now dependent upon this finite resource which is nearing its depletion phase. Moreover, at a time when we should be making massive cuts in the emissions of greenhouse gases into the atmosphere in order to reduce the threat posed by climate change, the food system is lengthening its supply chains and increasing emissions to the point where it is a significant contributor to global warming. The organic sector should be leading the development of a sustainable food system. Direct environmental and ecological impacts of agriculture ‘on the farm’ are certainly reduced in organic...

Economic, Social, and Environmental Benefits Associated With U.S. Organic Agriculture Organic Eprints
Lohr, Luanne.
This case study reviews the economic, social, and environmental benefits associated with organic agriculture in the United States. Measurable impacts are quantified by comparing indicators of benefits in counties with organic farms and counties without. Statistical differences across counties with and without organic farms provide preliminary evidence that organic farms may generate a variety of direct and indirect benefits. Of 36 indicators tested across a range of economic, social, and environmental benefits, 26 favor organic systems, three favor conventional systems, and seven are neutral. Even though organic farmers are not a large percentage of the total number of U.S. farmers, they may be influencing mainstream agriculture to shift toward greater...
