Sammendrag
Ensiling is a common mode of preservation of animal feed. In this process, the feed undergoes lactic acid fermentation in an anaerobic environment, which decreases pH and inhibits degradation of the feed and its nutritive value. Common silos include top loaded tower silos, side loaded bunker silos (also called horizontal silos), underground pit and trench silos, and bales and tubes wrapped in plastic film. Previous studies have revealed that the type of silo often have an impact on silage properties and feed value, but these effects can vary between silage materials. Silage density is another key factor for silage nutritive value and losses. Generally, high density results in smaller losses than low density, both in bunker silos and bales, but the density effect can also be influenced by properties of the ensiled material. The objectives of this literature review were to identify factors and conditions that can modify the effect of i) silage density, and ii) silo type on dry matter losses, leaching of nutrients, fermentation characteristics, silage feed value and mycotoxins contamination. A systematic literature search was carried out in in the Web of Science core collection platform of databases. Most studies showed positive correlations between silage density, and fermentation and feed value, and negative correlations with DM losses. The majority of these studies were conducted at laboratory scale and there was also a great variation in the magnitude of these effects. Further investigations at farm scale may provide more information about the consistency of these effects across experimental scales. The silo type comparisons indicate that silage bales, bags and tubes can be favourable for silage quality and dry matter preservation compared to bunker silos, but information on silo type effects on important crops such as maize is missing.

Kunnskapsutvikling for økologisk produksjon
Arbeidet med "Kunnskapsutvikling for økologisk produksjon" er et resultat av årlige tildelinger fra Landbruks- og matdepartementet (LMD). I det årlige tildelibgsbrevet beskrives styringssignaler og Stortingets budsjettvedtak for NIBIO for et år.

Visions and the consequences - analysing visions for Norwegian agriculture and its consequences for food security
In the FOSIP project (Visions and the consequences - analysing visions for Norwegian agriculture and its consequences for food security) we will assess and evaluate the foundation, support, opportunities, and limitations for the goal of increased agri-food self-sufficiency in Norway and assess how far an increase will contribute to improved national food security.

PRESIS
I PRESIS, et nytt femårig samarbeidsprosjekt, skal NIBIO være med å videreutvikle teknologiske løsninger for enda bedre presisjonsjordbruk, og samtidig sørge for at løsningene kommer ut i praksis til gårdene.
