Última Life cycle modelling of environmental impacts of application of processed organic municipal solid waste on agricultural land (EASEWASTE) Organic Eprints Hansen, Trine L.; Bhander, Gurbakhash S.; Christensen, Thomas H.; Bruun, Sander; Jensen, Lars S.. A model capable of quantifying the potential environmental impacts of agricultural application of composted or anaerobically digested source-separated organic municipal solid waste (MSW) is presented. In addition to the direct impacts, the model accounts for savings by avoiding the production and use of commercial fertilizers. The model is part of a larger model, Environmental Assessment of Solid Waste Systems and Technology (EASEWASTE), developed as a decisionsupport model, focusing on assessment of alternative waste management options. The environmental impacts of the land application of processed organic waste are quantified by emission coefficients referring to the composition of the processed waste and related to specific crop rotation as well as soil...

Ano: 2006 URL: http://orgprints.org/9235/1/9235.pdf Simulating root density dynamics and nitrogen uptake in the soil profile – A simple approach Organic Eprints Pedersen, Anders; Zhang, Kefeng; Thorup-Kristensen, Kristian; Jensen, Lars S.. We present a 2-D model for simulation of root density and nitrogen (N) uptake for crops grown in agricultural systems, based on a modification of Gerwitz and Page’s root density calculation. A root system form parameter was used to describe the distribution of root biomass vertically and horizontal in the soil profile. The form parameter can vary from 0 where root density is evenly distributed in the soil profile, to 8 where practically all roots are found near the surface. Additionally, the root model has other components describing root features, such as specific root length, N uptake kinetics. The root penetration rate and the depth distribution of root density were found to be the most important parameters controlling crop N uptake from deeper soil...

Ano: 2007 URL: http://orgprints.org/11361/1/Rodmodel_Artikel_Org_eprint.pdf Application of processed organic municipal solid waste on agricultural land - a scenario analysis Organic Eprints Bruun, Sander; Hansen, Trine L.; Christensen, Thomas H.; Magid, Jakob; Jensen, Lars S.. Source separation, composting and anaerobic digestion, with associated land application, are increasingly being considered as alternative waste management strategies to landfilling and incineration of municipal solid waste (MSW). Environmental life cycle assessments are a useful tool in political decision-making about waste management strategies. However, due to the diversity of processed organic MSW and the situations in which it can be applied, the environmental impacts of land application are very hard to determine by experimental means. In the current study, we used the agroecosystem model Daisy to simulate a range of different scenarios representing different geographical areas, farm and soil types under Danish conditions and legislation.
