Waste materials from biogas production - effects on soil fertility and climate

Anders Johansen,Mónica M. Carlsen,Henrik Hauggaard‐Nielsen,Anne-Kristin Løes-2011-09-26-Organic Eprints (International Centre for Research in Organic Food Systems, and Research Institute of Organic Agriculture)

TL;DRAbstract

Future agricultureal systems will produce bioenergy on basis of on- and off-farm crops and residues, implying beneficial recycling of plant nutrients back to soil and plants. This will reduce emission of climate gases and may also reduce spread of weed seeds, parasites and pathogens. However, it may also induce long-term reduction in soil organic pools.
