Energiebilanzen und Erträge ökologischer und konventioneller Anbausysteme: erste Analyseergebnisse eines Dauerfeldversuchs in Süddeutschland Organic Eprints
Bryzinski, Taras; Hülsbergen, Kurt-Jürgen.
An agrosystems trial in the south of Germany (near Munich) was established in 2009/2010 to quantify, analyze and model the effects of four organic and two non-organic agricultural systems on the yields, the soil and the environmental footprint. The differential und influential factors between the systems are: crop rotation, harvest index, plant protection and fertilization. The first results in the years 2011-2013 have shown significant differences in the crop yield (winter wheat) and the crop rotation yield (grain units) between organic and conventional systems and within this groups. The energy efficiency in plant production of organic systems with organic manure (digestate and slurry) are in the average of three years almost double as high as organic...

Kender vi vores lokale økologiske bæreevne? Organic Eprints
Seuri, Pentti.
Global set har menneskene på jorden udnyttet alle de vedvarende ressourcer, når vi når til septembermåned, og vi kan kun overleve resten af året ved at bruge af de lagrede ikke-fornybare ressourcer. Vi har faktisk brug for halvanden jordklode for fortsat at kunne producere alle de varer vi forbruger, men vi har kun én!

Organic farming without fossil fuels - life cycle assessment of two Swedish cases Organic Eprints
Sundberg, C.; Kimming, M.; Nordberg, Å.; Baky, A.; Hansson, P.-A..
Organic agriculture is dependent on fossil fuels, just like conventional agriculture, but this can be reduced by the use of on-farm biomass resources. The energy efficiency and environmental impacts of different alternatives can be assessed by life cycle assessment (LCA), which we have done in this project. Swedish organic milk production can become self-sufficient in energy by using renewable sources available on the farm, with biogas from manure as the main energy source. Thereby greenhouse gas (GHG) emissions from the production system can be reduced, both by substituting fossil fuels and by reducing methane emissions from manure. The arable organic farm studied in the project could be self-sufficient in energy by using the residues available in the...
