Publikasjoner
NIBIOs ansatte publiserer flere hundre vitenskapelige artikler og forskningsrapporter hvert år. Her finner du referanser og lenker til publikasjoner og andre forsknings- og formidlingsaktiviteter. Samlingen oppdateres løpende med både nytt og historisk materiale. For mer informasjon om NIBIOs publikasjoner, besøk NIBIOs bibliotek.

Skjemt silo og fôrrester ble lagt i kompost og prøvd ut som plantebed for ulike sorter squash. Plantene utviklet seg godt og ga tilfredsstillende avling.

Artikkelen presenterer en test av ulike typer oppalsjord som er Debio- eller Kravgodkjente. Begge de to jordblandingene som er Debiogodkjente gjorde det bra i utprøvingene.

Research from the last few years in our lab on the two potato pathogens Pectobacterium atrosepticum (Pba) and Clavibacter michiganensis (Cm) will be discussed. This includes studies of plant root affinity of Pba and bacteriocin sensitivity of Cm. For our studies we have used the available genome sequences, a mutation grid, real-time PCR and traditional techniques in biochemistry and microbiology.

The P norm for meadow, pasture, oil seeds and cereal crops is reduced by 25-30% to a balance level for input and output of P. A new correction system has a stronger reduction in P fertilization at high to very high soil P-AL levels than the old correction system, resulting in a faster decrease in the P-AL fraction over time when P-AL is high. No P fertilization is recommended at P-AL levels higher than 14. The combined effect of new P norms and correction system is expected to have a very marked effect on the use of P fertilizer as the reduction in P recommendations is about 50% or more at common P-AL levels (P-AL 10-15) in the soil.

In organic cereal production, restrictions on use of mineral fertilizers will in many cases reduce the P concentration in soil, and short term leys and catch crops will contribute to decrease the risk of P losses due to reduced erosion. However, the current means to control perennial weeds increase the risk of soil erosion and P loss. On organic farms with ruminants, the aim of self-sufficiency with fodder will often cause a low P-surplus, or even a P deficit on the farm level. This will reduce the P content in soil and thereby the P loss to the environment. However, if organic farming develops to include more intensive production systems with high animal densities and purchased fodder, such systems will be prone to the same risks of high P surplus and P losses as conventional farming systems. Outdoor housing for animal welfare is likely to further increase these risks, and environmental concerns such as reducing P losses from agriculture should be considered when organic farming systems are further developed.
