A Commodity Supply Mix for More Regionalized Life Cycle Assessments

Agricultural data for Life Cycle Assessments

On a world scale, a net transport of P to the oceans occurs, maintained by weathering of minerals and by erosion. The soil plays a different role regarding phosphorus in different agricultural systems. Without adding fertilisers, a soil can supply P for a limited time, by weathering or by mineralisation of indigenous organic matter. When a higher productivity is aimed at, fertilisers have to be...

III Agricultural data for life cycle assessments

An inventory for Life Cycle Analysis of agricultural products must address questions of representatively and coherence of models. This paper discusses the possibilities of modelling the input and production of typical farms to establish inventories that are consistent with higher level statistical information. Energy use has been modelled for typical Danish farms and compared with the national ...
