Miljø- og klimavennlig melkeproduksjon - Inspirasjon fra seks melkeproduksjonsbruk Organic Eprints
Hansen, Sissel; Bakke, Haavik, Torleiv; Bergslid, Ildri (Rose) Kristine; Elvatun, Helena; van Gool, Bart; Lunnan, Tor; Røthe, Gunnhild; Walland, Finn.
I denne rapporten presenterer vi seks gårder som viser at det er mulig å forene god økonomi med en miljømessig bærekraftig produksjon, men økonomien var best på de største gårdene. Felles for alle gårdene er næringsrik jord med god jordstruktur og god drenering, fokus på agronomi og godt husdyrstell. Dette resulterte i gode avlinger, god utnytting av tilførte næringsstoff, moderat bruk av energi og moderate utslipp av klimagasser. Fra observasjoner på disse gårdene og diskusjon på arbeidsseminar med gårdbrukerne, prosjektgruppe og inviterte gjester kan vi tipse om noen tiltak for miljøvennlig melkeproduksjon: god drenering, lite kjøring på våt jord, utføre jordarbeiding, gjødsling og høsting straks været og jorda er egnet, slepeslange med stripespreder i...

Yield and herbage quality from organic grass clover leys—a meta-analysis of Norwegian field trials Organic Eprints
Steinshamn, Håvard; Adler, Steffen A.; Frøseth, Randi Berland; Lunnan, Tor; Torp, Torfinn; Bakken, Anne Kjersti.
A meta-analysis based on experiments in organically cultivated grasslands in Norway was conducted to quantify the effects of management factors on herbage yield and feed quality. A dataset was collected that included 496 treatment means from experiments in five studies carried out at eight locations with the latitude range of 58.8 to 69.6 N between 1993 and 2010. We tested the effect of harvesting system (two vs. Three cuts annually), plant developmental stage at the first cut, growth period (temperature sum) and the herbage clover proportion. Plant maturity at the first cut and herbage clover proportion explained to a large extent herbage yield and quality of the first cut and annual yield. The timing of the first cut influenced also the yield and herbage...

Effects of renewal time, taproot cutting, ploughing practice, false seedbed and companion crop on docks (Rumex spp.) when renewing grassland Organic Eprints
Ringselle, Björn; Berge, Therese W.; Stout, Daniel; Breland, Tor Arvid; Hatcher, Paul E.; Haugland, Espen; Koesling, Matthias; Mangerud, Kjell; Lunnan, Tor; Brandsæter, Lars Olav.
Docks (Rumex spp.) are a considerable problem in grassland production worldwide. We investigated how different cultural management techniques affected dock populations during grassland renewal: (I) renewal time, (II) companion crop, (III) false seedbed, (IV) taproot cutting (V), plough skimmer and (VI) ploughing depth. Three factorial split-split plot experiments were carried out in Norway in 2007–2008 (three locations), 2008–2009 (one location) and 2009 (one location). After grassland renewal, more dock plants emerged from seeds than from roots. Summer renewal resulted in more dock seed and root plants than spring renewal. Adding a spring barley companion crop to the grassland crop often reduced dock density and biomass. A false seedbed resulted in 71%...
