Riverine inputs and direct discharges to Norwegian coastal waters in 2012 have been estimated in accordance with the requirements of the OSPAR Commission. Water discharges in 2012 were lower than in 2011, but higher than the 30-year normal. This caused a small but overall decrease in inputs since 2011, with an exception of zinc, which increased in the overall loads due to an increase in River Glomma. The reason is presently unknown. Analyses of data since 1990 from nine main rivers in the program revealed downward trends both for nutrients and metals, with an exception of upwards trends for ammonium in one river. Fish farming continued to be a major source of nutrients, with an increase of about 15 % of phosphorus and nitrogen loads since last year. Inputs of PCBs and the pesticide lindane were, as in previous years, insignificant

Abstract
We report results from trials on chicory growth (experiment 1) and lamb growth on chicory (experiment 2). In experiment 1, we assessed yield and chemical composition on swards established under organic conditions as perennial ryegrass/red clover, perennial ryegrass/chicory, chicory/red clover (CHRC), pure perennial ryegrass (RG-alone) and pure chicory (CHalone) over two years. Chicory/red clover and CH-alone showed improved crude protein, Ca, Mg, P, Cu and net energy contents compared to other mixtures. However, dry matter yield was the lowest for CHRC and CH-alone compared to others. In experiment 2, 48 weaned lambs grazed swards sown as chicory alone (CHA), chicory–grass–clover mix (CGC) or grass–clover mix (GCM) for 45 days. Lamb body weight (BW) gain and final BW were higher on CHA and CGC than on GCM. The results suggest that chicory can complement conventional grass/clover swards especially in macro- and micronutrients for improved lamb growth with a proper grazing management in place
