In this report we have recorded the process of relocation of cattle barn and the utilization of final products of biogas plant system.In this decade our experimental farm has provided larger field for some university buildings and facilities, Center for Advanced Science and TechnoIogy (1998), horse club's field (1999), Co-Labo Hokkaido (1999) and Heisei poplar avenue (2000). After that, big research institutions were planned and decided to construct. Since the area for these buildings and for long term university plan contained the site of old cattle barn, our old cattle barn with some experimental fields needed being moved from the field. The buildings, Creative Research Institute Sousei (2003) and Frontier Research for Post-Genomic Science and Technology (2004), are now started to use.Newly constructed cattle barn at the first experimental farm field has been used from November 2003. The barn contains biogas plant system (BPS). A large amount of fermented manure has been produced from the BPS. Totally 1051.1 m³ manure was scattered and 750.8 m³ was used as fertilizer in 4.85 ha-forage crops and grasses fields. One of the problems in BPS was that trapped hay at the first pit made troubles in transfer of manure to fermentation tank. This caused increasing volume of fermented manure in 2004.It is necessary to trace the details of the effect of manure from BPS on soil and reflecton the management of crops and grasses production after next year.
