Johansen , Anders; Hauggaard-Nielsen, Henrik; Ambus, Per and Carter, Mette S. (2009) Recycling of bioenergy waste-stream materials to soil in organic farming systems. Poster at: NJF Seminar 422 , Tartu in Estonia, 25-27 August 2009.
The poster present data on how de-gassted waste-stream material affect soil quality parameters in comparence to raw manure and clover-grass application. The results showed that residues after bio-gasification seems suited for fertilizer usage and not much different from application of raw cattle manure. However, the long-term effects on soil organic matter content needs to be further clarified. Application of clover-grass to the soil caused a significant loss of C and N due to gaseous emissions.
