Wood for outdoor decking has a high marked share in the Nordic and Baltic countries among private house owners. Important issues for the consumer are maintenance intervals and aesthetic appearance as well as decay resistance. Knowledge and consumer information about these aspects are required to ensure that wood can compete with alternative decking materials. In this paper an accelerated testing of decking, “stapelbäddsmetoden”, was evaluated after six years of exposure at Ås, Norway, and compared with earlier reported results after three years. Twelve different preservatives and wood modification treatments were used in addition to untreated Scots pine (sapwood and heartwood) and larch (heartwood). The samples were treated with two different surface treatments. In addition there was one set without any surface treatment. In this method for accelerated testing, discolouration and decay was evaluated. This provided new information about performance both on and above ground for a range of different combinations of preservative/modified systems and surface treatments of wood in decking for outdoor use. For example, no clear differences were found between the surface treatments and no surface treatment. The wood modifications with styrene and furfurylalcohol performed just as good, or better, than the copper containing treatments.

Delt gjødsling er vanlig i rug for å gi optimal avling og kvalitet. Forsøk har vist at rug er relativt fleksibel med hensyn til egnet delgjødslingstidspunkt (begynnende stråstrekning eller flaggbladutvikling) og at det er liten avlingsrespons på svovelgjødsling utover 0,8 kg S pr. daa.

Extensive damage by the needle parasites Delphinella abietis and Herpotrichia parasitica (Herpotrichia Needle Browning) was recently observed at the west coast of Norway. D. abietis was by far the most widespread, but once established in the field, the damage potential seemed to be equally high for both pathogens. D. abietis occurred on subalpine fir (Abies lasiocarpa), Turkish fir (A. bornmuelleriana), Siberian fir (A. sibirica), and nordmann fir (A. nordmanniana) in Christmas tree plantations, and minor damage was seen on Noble fir (A. procera) for bough production. H. parasitica was found on Turkish fir and nordmann fir in Christmas tree plantations. None of the diseases are new to Abies spp. in Norway, but they have not previously been reported from Christmas tree fields.

Soppane Delphinella abietis and Herpotrichia parasitica gjer begge stor skade i nokre edelgranfelt på Vestlandet. Delphinella er mest utbreidd av dei to og gjer omfattande skade frå Hardanger og nordover. Begge soppane er luftborne og angrip nålene.
