Using split fertilization of nitrogen (N) in wheat production is today well-established to increase protein content and adjust fertilization. However, deep knowledge and understanding of N uptake and remobilization during late stages of crop development are missing. Moreover, while split fertilization requires fast dissolution of fertilizers, information on amount of precipitation/moisture needed is currently lacking. The project will, by pot- and field trials as well as a lab-study, explore the following principal questions: How late can N be applied and still result in increased yields or higher protein content in wheat? Can nitrogen use efficiency increase by late N application? How much precipitation/moisture is needed to dissolve different fertilizers? New knowledge can be implemented in practical farming. Information on dissolution of fertilizers can result in more precise N-doses and increased knowledge regarding crop potential can improve profitability in production.
Delade givor av kväve (N) i veteodling är idag väletablerat för ökad proteinhalt och behovsstyrd gödsling. Däremot saknas djupare kunskap kring N-upptag och omlagring sent i grödans utveckling. Vidare kräver delade N-givor att tillfört gödselmedel snabbt kan lösas upp och bli växttillgängligt, där kunskap kring vilken nedbördsmängd eller fukthalt som krävs för detta saknas. Projektet kommer, i form av kärl- och fältförsök samt en labbstudie, belysa följande övergripande frågeställningar: Hur sent i grödans utveckling kan vi tillföra N till vete som ger effekt i form av ökad skörd eller proteinhalt? Kan vi öka N-effektiviteten med hjälp av sena givor? Hur mycket nederbörd/fukt behövs för upplösning av olika gödselslag? Kunskap från projektet kan direkt tillämpas i praktisk odling. Information kring upplösning av gödselmedel medför att kommande N-givor kan behovsanpassas bättre och med ökad kunskap om grödans potential kan vi effektivisera N-gödslingen och öka lönsamheten.

Insulin resistance and obesity are common in humans and horses. There is a strong correlation between insulin resistance and laminitis in horses but the pathogenesis of laminitis is not known. One hypothesis is that the development of laminitis is related to an insulin induced dysfunction of the …

The aim of the proposed project is to examine whether recovery after competition in horses is affected by housing system. Our hypothesis is that horses kept in a housing system where they can move freely in groups recover faster than horses kept in box stalls. We performed such a study in 2015 and, …

The invasive fruit fly Drosophila suzukii is spreading in Sweden, from detection of only a few individuals in 2014, to damage in raspberry in 2015. Considering its multibillion € footprint in the EU and US, we urgently need to analyze the crops at risk, and establish measures to minimize spread and …
