Begrenset næringstilførsel er viktig for å oppnå grøntarealer med lite behov for slått og skjøtsel. Her presenteres resultater som viser at bruk av små mengder slam og kompost ved etablering av vegetasjon på undergrunnsmasser kan gi sikker etablering av grasvegetasjon med lite behov for skjøtsel.

Riverine inputs and direct discharges to Norwegian coastal waters in 2011 have been estimated in accordance with the requirements of the OSPAR Commission. Due to high water discharges in 2011, the riverine inputs of both nutrients and metals were greater than 2010. 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 nitrogen in one river. Fish farming continued to be a major source of nutrients and copper to coastal waters. Inputs of PCBs and the pesticide lindane were, as in previous years, insignificant.

Abstract Strict control of morphogenesis is essential in production of potted poinsettia. Commonly, this is obtained by the use of plant growth retardants (PGRs), often in combination with early morning temperature drops. Due to negative effects on human health and the environment, the use of PGRs is becoming restricted. Also, energy-saving growth regimes and periods of high temperatures limit effective use of temperature drops. In the present study the use of a high proportion of blue (B) light provided by light emitting diodes [LEDs, 20% blue (B), 80% red (R)] was compared with traditional high pressure sodium (HPS) lamps (5% B) providing similar phytochrome photostationary state to produce compact poinsettia plants. Both in the greenhouse and growth chamber, all cultivars were 20–34% shorter for LED compared to HPS grown plants. Also, leaf and bract area as well as chlorophyll content and total dry matter accumulation were lower under LED. The LED did not delay bract color formation, visible cyathia and flowering compared to HPS, and no difference in post production performance (cyathia/bract abscission or necrosis) between the two light treatments was found. The effect of end of day-red (EOD-R) lighting combination with LED and HPS supplemental lamps during the photoperiod in the greenhouse was also investigated. Reduced stem extension (13%) was observed under HPS only and for one of the two cultivars tested, whereas under the LED regime, there was no effect of EOD-R lighting.

Årlig omsettes 7-800 tonn frø av ca. 15 grasarter/underarter til norske grøntanlegg. Rødsvingel, engrapp og flerårig raigras står for mer enn 90 % av omsetningen. Denne artikkelen gir først en oversikt over de viktigste egenskapene til de ulike artene/underartene. Deretter anbefales arter for green, fairway, prydplen, skyggeområder, teesteder, fotballbaner og landskapsformål.
