Oilseed rape (OSR) is a profitable and important crop in Swedish agriculture, especially winter OSR which is cultivated on approximately 100000 ha each year. Cultivation of OSR relies on large inputs of fertilizers and pesticides, which has economic costs as well as negative environmental impacts. In this project, we will develop multifunctional intercropping of winter OSR and legumes to reduce weeds, pathogens and pests and replace some of the nitrogen (N) fertilizer inputs with biologically fixed N. Field experiments will be conducted with both frost sensitive legumes that die during winter and overwintering grain legumes that are harvested together with winter OSR. The experiments will compare management for optimal OSR yield with reduced inputs in terms of N fertilizers, weed and pest control in intercrops. The results will be used for evaluations of the economic, environmental and social sustainability of the different intercrops compared to OSR and grain legume sole crops.
Raps är en lönsam och viktig gröda för svenskt jordbruk, särskilt höstraps som odlas på närmare 100000 ha varje år. Rapsodling kräver dock stora insatser i form av gödsling och bekämpning av ogräs och skadegörare, vilket innebär såväl betydande kostnader som negativ miljöpåverkan. I detta projekt ska vi utveckla mångfunktionell samodling av höstraps och baljväxter för att minska ogräsmängden och förekomsten av skadegörare, och samtidigt minska behovet av kvävegödsling via baljväxternas biologiska kvävefixering. Fältförsök kommer att genomföras med både frostkänsliga baljväxter som dör under vintern och övervintrande baljväxter som skördas tillsammans med raps, och med olika skötselintensitet (kvävegödsling och kemiskt växtskydd för maximal rapsskörd jämfört med reducerad mängd insatsmedel). Försöksresultaten används för att utvärdera odlingens hållbarhet utifrån miljömässiga, ekonomiska och sociala aspekter hos de olika samodlingarna jämfört med raps och trindsäd i renbestånd.

The ability of milk to coagulate is crucial for cheese production. We have previously shown high occurrence of non-coagulating milk from Swedish Red Dairy cattle and identified milk proteins as potential markers for this undesirable trait. In this project we will increase the understanding of the …

A sustainable use of phosphorus fertilizers has engaged a large number of researchers, especially how to measure
the soil content of available phosphorus. However, the development of results to useful methods for agriculture has
not been a priority. The recommendations are based on extraction with …

We need to remediate the capacity of agricultural landscapes to retain water, nutrients and sediments to make them
more resilient to the increasing frequency of flooding, drought and pollution expected with the climate change. It can
be done by remediating existing narrow ditches into ditches with …

It is well known that storage of animal manure and digestate causes emissions of methane (CH4), nitrous oxide (N2O) and ammonia (NH3). A crust on liquid manure acts both as a physical barrier for NH3 and as a biofilter that oxidize CH4 and NH3. However, N2O can be formed in some crusts, and there …
