Low soil temperatures limit nutrient uptake with negative consequences for growth and foliage quality. A better understanding of the temperature sensitivity of root N uptake is required to improve the best management practices for fertilization of conifers. Uptake of 15N in saplings of Abies lasiocarpa (Hook) Nutt and Abies nordmanniana (Steven) Spach was studied at root temperatures of 3 - 15°C in hydroponics. 15N accumulation in shoots increased with temperature, showing accelerated accumulation from 7°C upward. At 3°C, uptake rates were low for both species. Between 7 and 12°C, 15N accumulation in shoots increased by a factor of 5 in A. lasiocarpa and by a factor of 3 in A. nordmanniana. The temperature response of N uptake was similar to root growth responses to temperature documented by previous studies. The results have implications for early season fertilization, where fertilization of both species should be withheld until soil temperatures reach 10 -12°C.

Norwegian lamb meat production is mainly based on free grazing in mountainous pastures during the summer. Prior to slaughter in the autumn, some lambs not big enough for slaughter are finished on e.g. cultivated pastures. This study looked at the feed quality of different forages, and the effect on lamb meat quality. Lambs grazed on mountain pastures at Kvaløya in Northern Norway (69°N) and Sør-Fron in Mid Norway (58°N) in 2007, and a subgroup at each location was finished on cultivated pastures for 6 weeks prior to slaughter in September. The fiber content was significantly higher in the cultivated pasture in Mid Norway compared to the mountain pasture while no differences between pastures in Northern Norway were found. In Mid Norway the content of polyunsaturated fatty acid (18:3) was significantly higher in meat from lambs grazing the mountain pasture compared to lamb grazing the cultivated pasture. For Northern Norway, the opposite pattern was observed. The higher 18:3 content may be attributable to lower fiber content at the mountain pasture. In our study, there appears to be an effect of fiber content on the fatty acid composition in lamb meat.

I de nye kostrådene fra Nasjonalt råd for ernæring er poteten tatt ut fra anbefalingen om å spise 5 porsjoner daglig med grønnsaker, frukt og bær. Begrunnelsen er manglende dokumentasjon omkring helseeffekt av poteter. Dette har skapt engasjement, blant annet i Fagforum Potet, som ønsker å få frem argumenter for potet som en sunn matvare. Intensjonen med de nye kostrådene har vært å bedre den norske folkehelsen. Fagforum Potet mener at å fjerne poteten fra anbefalingene vil virke mot sin hensikt. Norge har allerede et av Europas laveste potetforbruk samtidig som negativ fokus i media har gjort at mange ikke regner poteten som sunn. Dette kan bli forsterket når potet ikke lenger anbefales inkludert i "5 om dagen". Fagforum Potet mener at den negative omtalen i høyeste grad er ufortjent, og at redusert potetforbruk på sikt kan påvirke folkehelsen negativt. Det er tvert imot mange gode grunner til å anbefale potet som en sunn og næringsrik bestanddel i kostholdet. Poteten tilfredsstiller mange av de generelle kjennetegnene til frukt og grønt, som lav energitetthet og gunstig ernæringsmessig sammensetning, I tillegg gir den lite miljøbelastning i form av CO2. Den er også en viktig kulturbærer i Norge, med sin gode smak og unike variasjonsmuligheter.

Oil transportation from the Russian part of the Barents Region along the Norwegian coast had insignificant volumes before 2002. However, in 2002 there was a dramatic increase in oil shipment, when 4 million tons was delivered westwards by the Barents Sea. In 2003, the volume reached 8 million tons. The trend continued in 2004, and about 12 million tons of export oil and refined products were transported from the Russian part of the Barents Region to the western market along the Norwegian coast. From 2005 to 2008, the annual shipment volumes were on the levels between 9.5 and 11.5 million tons. In 2009, Russian oil-and-gas export cargoes carried by the Barents Sea rose to 13 million tons, and in 2010, exceeded the level of 15 million tons. Norwegian Snøhvit, the first offshore production in the Barents Sea, added to these volumes 5 million cubic metres of liquefied gases (LNG and LPG) each of two recent years. The terminals loading oil for export in the Russian Western Arctic seas have been continuously developed, and the overall shipping capacity has been enlarged. The changes in oil volumes carried for export through the Barents Sea during the recent years were not so much dependent on the terminals‟ capacities and logistic schemes as on the external factors. The changes in the export taxes by the State and rates for cargo transportation by Russian railways, development of new trunk pipelines and sea terminals in the Baltic Sea and Far East by Transneft, bankruptcy of Volgotanker were a few examples that induced oil transport operators to develop new terminals in the Kola Bay and to focus more on petroleum products than crude oil. The big oil export challenges that occurred in the recent years due to conflicts between Russia and neighbouring transit countries made the Russian Government and Transneft to reorient the Russian oil export routes and increase the capacities of the Baltic Pipeline System (BPS) to 75 million tons in 2007, with the prospects to reach 150 million tons in 2015. Construction of Eastern Siberia-Pacific Ocean pipeline (ESPO) was launched, the first phase with a branch to China was put on stream in 2010, and a new terminal in the Far East started to ship oil for export. In the south, the project of Burgas-Alexandropoulis pipeline was developed. In the north, Kharyaga-Indiga pipeline project was frozen because a new Varandey terminal came on full scale. The year of 2009 started with an export gas transit conflict between Russia and Ukraine. The Government of Russia and Gazprom highlighted the importance of constructing Nord Stream and South Stream gas pipelines through the Baltic and the Black seas to let Russia export natural gas to Western Europe bypassing its neighbouring countries, the former Soviet sister-republics. In 2009, Russia launched its first LNG plant in Far East in Sakhalin. Three more LNGs are planned in the Arctic, in the Kola Peninsula, in Nenets region, and in Yamal. Those plants can start shipping liquefied gas in 2016-2017. The first oil from offshore production in the Russian Barents should come from Prirazlomnoye oil field. Prirazlomnaya platform left Severodvinsk and came to Murmansk for completion in the fall of 2010. The plan is to deliver the platform on its production destination and put the oil field on stream in 2011. The Prirazlomnaya platform will be the second big offshore installation in the Pechora Sea. The first one, 12 million tons Varandey terminal, was launched in 2008, and already in 2009 sent more than 7 million tons of crude oil for export. Lukoil plans to increase the terminal oil offloading volumes building 8 million tons pipeline from Kharyaga to Varandey. In the present report on oil transportation in the Barents Region, we have given special attention to the description of the existing and prospective offshore and onshore oil and gas terminals in the northern regions of Russia and Norway, and their connection to hydrocarbon reserves on one hand and to the export routes on the other. We demonstrate that even without a Russian oil trunk pipeline to the Barents Sea coast, that was discussed a few years ago, the overall capacity of the terminals shipping oil and gas for export along the northern coast of Russian and Norway can reach 100 million tons in five years perspective. In Russia, about 50 million tons of crude oil and petroleum products can be delivered by railway to the Murmansk port terminals in the Barents Sea, and Kandalaksha and Arkhangelsk in the White Sea. In addition, up to 20 million tons of oil will come from the northern Timano-Pechora oil fields - 12.5 million via the new Varandey terminal, and 7.5 million from Prirazlomnoye field. Dolginskoye oil field, which is estimated to be three times as big as Prirazlomnoye, will be the next large offshore field in the Pechora Sea put on stream. With port infrastructure developed on Yamal, the terminals in the Kara Sea can ship 3 million tons of Western Siberia crude oil for export. Shtokman in the Barents Sea and Tambey in Yamal gas fields can offload 12.5 million tons of liquefied gas in 2017, when the first phases of both LNG plants are completed. In Norway, in addition to 5 million tons of liquefied gas shipped from Snøhvit, Goliat oil field in the Barents Sea should be put on stream in 2013 and produce 5 million tons of oil in 2014. In 2010, there were made a number of historic voyages by the Northern Sea Route. We will see more cargo vessel passages through this Arctic shipping lane in 2011. In a long term perspective, the Northern Sea Route will give the way for huge Yamal and Kara Sea oil-and-gas resources to the western markets via the Barents Sea; and it will also open possibilities for transit cargo transportation from Europe to Asia Pacific along the Arctic coast. In the European part of Russia there are three possibilities for shipping oil for export - through the Black Sea, the Baltic Sea, and the Barents Sea. Out of these three options, only the northern way can provide the stable cargo shipping directly to major European and North American harbours, avoiding transit challenges through neighbouring countries or heavy traffic in the sea straits. Oil pollution prevention should be the central issue during oil transportation in the Barents Sea. The year 2010 was marked with the Mexican Gulf accident, the largest oil spill ever happened in the sea that put issues of marine environmental protection against oil pollution to a high international political agenda. In this report, we pay attention to the environmental safety matters in oil transportation and Norwegian-Russian co-operation in the oil pollution prevention. We see more advanced and safer terminals and vessels operating in the region. However, the number of accidents with sea vessels was increasing worldwide the last 10 years due to human errors. Traffic control and monitoring are developed both in Norway and Russia. Establishment of an early warning and notification system between two countries should be the next step. The Treaty on a delimitation line in the Barents Sea, that was signed between Norway and Russia in 2010 and ratified in 2011, should put relations between two countries on a new level opening wider possibilities for oil-and-gas, maritime shipping and environmental cooperation.
