| Production of bioenergy in organic agriculture may be implemented in the future to reduce the reliance on non-renewable fossil fuels and minimize greenhouse gas (GHG) emissions. Therefore it is important to assess the potential effect this may have on soil quality and biological parameters. This project aims at designing and evaluate a combined concept for biomass and bio-energy production in OA, while considering soil bio-geo-chemical cycling of plant nutrients and biodiversity of the soil microbiota. |

| The FASSET whole farm model was extended with a sub-model for competition between several plant species for light, water and nitrogen. The new model was tested on intercrops of pea (Pisum sativum L.) and spring barley (Hordeum vulgare L.). A three-year dataset on pea and barley sole crop growth was used for calibration. Two datasets that included detailed measurements of crop production, nitrogen uptake and leaf area indices from two sites were used for testing. An arable organic experiment from three sites including several treatments over four years was also used for testing. The model predicted the increase in resource utilisation of pea and barley and effects on pea symbiotic nitrogen fixation satisfactorily. The effects of pea interspecific... |
