Ny rapport fra Nibio konkluderer med at helmekanisert tynning ofte ikke er lønnsomt. Men skal man tynne lønner det seg best på gran – gjerne et sent inngrep med 25-35 prosent uttak. Det er avgjørende at selve tynningsdrifta går i pluss.

Butyric acid and its derivatives are widely applied in aquaculture as an alternative to antibiotics, which are beneficial for the growth and health of aquatic animals. However, these products have some disadvantages including poor stability, a bitter taste, and low bioavailability. In this study, a novel butyric acid, namely pentabutyryl glucose ester (PGE), was synthesized, and the effects of PGE on the growth, liver and intestinal health, and gut microbiota of zebrafish were evaluated. We found that the supplementation of PGE at a level of 0.05% promoted the growth performance of zebrafish, decreased the level of serum LPS, ALT, and AST, and improved liver health. The expression levels of pro-inflammatory factors (NF-κBp65 and IL-6) were notably downregulated, while those of anti-inflammatory factors (TGF-β and IL-10) were upregulated, in the intestines of zebrafish fed 0.05% PGE compared with the control group. Additionally, inclusion of PGE in the diet of zebrafish increased the relative abundance of probiotic bacteria such as Bacillus and Lentilactobacillus. Overall, this study demonstrated that PGE is beneficial for the growth, liver and intestinal health, and the gut microbiota of zebrafish, providing a novel pathway to improve the application of butyric acid as a feed additive in aquaculture.

To better understand the increasing human impact on the water cycle and the feedbacks between hydrology and society, the International Association of Hydrological Sciences (IAHS) organized the scientific decade “Panta Rhei – Everything Flows: Change in hydrology and society” (2013–2022). A key finding is the need to use integrated approaches to assess the co-evolution of human–water systems in order to avoid unintended consequences of human interventions over long periods of time. Additionally, substantial progress has been made in leveraging new data sources on human behaviour, e.g. through text mining of social media posts. Much has been learned about detecting hydrological changes and attributing them to their drivers, e.g. quantifying climate effects on floods. To achieve further progress, we recommend broadening the understanding, the discipline and training activities, while at the same time pursuing synthesis by focusing on key themes, developing innovative approaches and finding sustainable solutions to the world’s water problems.

No-till systems grounded in the principles of conservation agriculture can restore the soil organic carbon (SOC) stock and environmental sustainability. Here, we assessed the SOC stocks to 1-m depth for three land-uses (i.e., native vegetation - NV, no-till system – NTS, and plow-based tillage - PBT) across 26 sites in the Cerrado and 37 sites in the Atlantic Forest biomes of Brazil for 3402 soil samples. The depletion of SOC stocks under PBT compared to NV was equivalent to a loss of 38.1 % and 45.8 % of the original NV SOC stock for Cerrado and Atlantic Forest biomes, respectively. The SOC stocks of 16 NTS sites exhibited levels that exceeded those under NV, and SOC stock was restored from 80 to 100 % of its NV levels in 27 other NTS sites across the Brazilian biomes. The SOC stock at seven of 13 edaphoclimatic zones (Clusters) was comparable to or more than that under NV. The duration of NTS to restore SOC stock to that under NV ranged from 36.4 to 55.0 years for the Cerrado and Atlantic Forest biomes, respectively. The NTS/NV SOC stock ratio indicated that one hectare of land under NTS has the potential to avert deforestation for food production of 0.81 ± 0.18 to 1.01 ± 0.15 ha of NV in the Brazilian biomes. In essence, NTS has been demonstrated to effectively restore SOC stocks in Brazil's biomes and play a pivotal role in integrating agriculture as a part of the solution for mitigation strategies for climate change.

Warmer temperatures due to global warming and use of climate-enhancing fbre covers makes it important to gain specifc knowledge of the temperature response in potato cultivars grown under Midnight Sun in northern Scandinavia. The temperature response was therefore studied in climate-controlled growth chambers under constant temperatures from 9 to 21 °C under a natural 24-h photoperiod in a greenhouse in Tromsø (69.7°N, 18.9°E), Norway, for the potato cultivars Gullauge (medium late) and Mandel (late). There was a strong response in both cultivars to temperature, with reduced developmental time from emergence and leaf formation to visible fower buds at increasing temperature intervals. Emergence was earlier for Gullauge than for Mandel, followed by no diference in development time between cultivars for subsequent developmental stages. Shoot dry matter weight per plant was highest at 12 °C and 15 °C for both cultivars, although with higher shoot biomass at harvest in Mandel than in Gullauge. Tuber yields and tuber dry-matter percentages were higher for Gullauge than for Mandel. Fresh weight yields and dry matter percentage for both cultivars were highest at 15 °C. Optimum temperature for above-ground vegetative development-rate was estimated to be 24.0 °C and 22.6 °C, for Gullauge and Mandel, respectively. In contrast, the respective temperature optima for developing tuber dry matter content were 16.6 °C and 15.6 °C. Lower temperature optima for below-ground developme below ground with optimumsa of around nt make potato a suitable crop for temperate and boreal climates with cooler autumn temperatures. Diferent temperature response for above- and below-ground development may be used for decision about when to remove climate-enhancing covers in response to the temperature during the season. This diference may also be important for developing temperature-based growth models for potato cultivars from emergence to tuber yields.
