Abstract

This report aims at presenting the basis for recycling ash from energy crops, primarily straw ash, to the agricultural soil from which the biomass has been harvested. The Danish experience with recycling ash is reviewed and the composition of ash with respect to nutrients and trace elements is reviewed. A balance is computed and recommendations for methods to recycle straw ash in Sweden are given.
