In the 1940s and 50s, spruce trees were planted in large areas in Northern Norway. These forests are now reaching maturity for harvesting. However, a long-standing question has been whether northern Norwegian spruce sawn timber has sufficient strength properties for use in load-bearing structures. According to new studies, the answer is yes.

Each year, between 160 and 220 ha of turfgrass sod are laid in Norway. Increased use has raised questions about whether sod production leads to loss of agricultural soil. NIBIO has recently documented how much soil is removed during sod harvest – and what producers can do to reduce this loss.

Forest volume in Norway has now surpassed one billion cubic metres. One hundred years ago, the volume was around 300 million cubic metres. At the same time, new analyses show that in some regions more timber is being harvested than is growing back. This marks a significant break from the last 100 years, where annual growth far exceeded logging.

Seaweed cultivation represents an emerging industry in Europe, where most biomass is still derived from wild harvesting. A potential approach to establishing a sustainable seaweed production industry involves improving seaweed strains. Temperature priming, introducing moderate stress to enhance subsequent performance, offers a rapid approach for improving growth. We examined the effect of three weeks temperature priming (0, 10, 20 °C) of gametophytes of Saccharina latissima on the early life stages (gametophyte growth, sporophyte recruitment, juvenile sporophyte growth). Cold priming (0 °C) stimulated gametogenesis and produced significantly larger microscopic sporophytes. This size advantage of the juvenile sporophytes was carried through a temperature gradient experiment (0–21 °C) over two weeks, especially under optimum temperatures (5–15 °C). In a second experiment with a similar gametophyte priming approach, we cultivated sporophytes for six months in mariculture and investigated size, biomass and biochemical composition. Biomass of sporophytes from 0 °C primed gametophytes was twofold higher than of 10, and fourfold higher than of 20 °C-primed gametophytes. The difference in mineral composition in sporophyte blades between priming treatments was variable. Heavy metals (As, Cd) were lower under warm priming (20 °C) and few macro- and trace elements (K, P, S, Mn) significantly increased under cold priming. The results demonstrate a transgenerational carry-over effect from haploid gametophytes to diploid sporophytes and underscore the significance of gametophyte cold exposure for the growth of S. latissima sporophytes. It suggests that cold priming of gametophytes may serve as a form of winter mimicry to enhance growth and to modify biochemical composition in kelp cultivation.
