The main goal of this study was to develop an alternative bedding material for cattle and sheep based on locally produced woodchips from birch trees and Sphagnum peat in Northern Norway. Four litter mixtures; 2.5 and 5.0 cm woodchips, with and without 20 % peat of total volume were studied in A) Four pens sized 20.4 m2 with two cattle each, ie one pen per treatment; B) Eight pens sized 21.2 m2 with seven ewes each, ie two pens per treatment, and two similar sheep pens with deep straw (barley) as controls. The number of lying animals was counted in 10 minutes’ intervals from 6 pm to 6 am for two consecutive days and the mean number of animals lying simultaneously per pen and hour, was calculated. The cleanliness of the animals was assessed within three separate body sections (legs, side, rear) using a scale from 0-2 points for each body part (0 p=clean, 6 p=dirty). The proportion of animals lying simultaneously per pen and hour and individual cleanliness scores were analysed by GLM. No differences in lying behaviour and cleanliness between the four woodchips mixtures were found, neither for sheep nor cattle. However, straw bedding resulted in the least dirty ewes (P

Camelina is an underexploited oilseed crop that may be well suitable for cropping innorthern areas. The oil is particularly high in the omega-3 fatty acid alpha-linolenic acid (C18:3n-3). The aim of the present study was to evaluate the potential for secure production of high quality edible oil from organically grown camelina (Camelina sativa L. Crantz), focusing on the effects ofenvironmental parameters on oil content, fatty acid composition and contents of phytosterols and tocopherols. Field experiments with pre-crop barley were conducted in the growing seasons 2007, 2008 and 2009. Trials were fully randomized with two levels of Nitrogen (N) fertilization, 0 and 120 kg total Nha-1, and two levels of Sulphur (S) fertilization, 0 and 20 kg total S ha-1. Additional experiments were performed in 2009 in order to evaluate the effects of replacing pre-crop barley with pre-crop pea. Crude oils were obtained by usinga pilot press and the fatty acid composition and contents of phytosterols and tocopherols were analyzed by GC-MS and LC-MS. The results showed significantseasonal variations in the contents of fatty acids, tocopherols andphytosterols. Furthermore, significant effects of N-fertilization were observed, with increased contents of C18:3n-3, erucic acid (C22:1) and γ-tocopherol at the highest level of N-fertilization. Pea compared to barley as pre-crop also increased the content of C18:3n-3. There were no effects of S-fertilization. Principal component analysis revealed positive correlations between the contents of C18:3, C22:1, γ-tocopherol and phytosterols, in particular brassicasterol. In conclusion, camelina seems to be well suitable for organic cropping. The oil quality was influenced by season and N-fertilization, still, the variation in nutrient content was small.

Små opplegg knyttet til forskning rettet mot elever i 10 klasser. Vi forklarte og viste hvordan husdyrgjøsel kan brukes til å lage gass, at det er bakterier som er viktige. vi såg også på ulike rotknoller på belgvekster hvor det lever tusenvis av bakterier som kan gjøre nitrogengass i lufta om til nitrogenholdige stoffer som planten kan bruke. Biologi trengs for at det skal skje kjemi.

Utilizing animal slurry to produce biogas may reduce fossil fuel usage and emissions of greenhouse gases. However, there is limited information on how the recycling of digested slurry as a fertilizer impacts soil fertility in the long run. Anaerobic digestion decreases the content of organic matter in the slurry and organic farmers are concerned that this will deplete soil organic matter pools. This will be studied in the SOILEFFECTS project, initiated in 2010 at an organic research farm in Tingvoll, Norway. A local biogas plant produces anaerobically digested slurry, to be compared with non-digested slurry in perennial ley and arable crops. Effects on crop yields, and a range of soil characteristics will be measured
