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.

The goal of the project is to digitize the data from the Swedish official field trials through automated estimates of important traits such as germination, growth, resistance, maturity and the effect of plant protection products. The purpose is to streamline and improve scoring of both diseases but …

A cornerstone of the Swedish Food Strategy is trust in Swedish food production. Yet each year Swedish farmers and food processors lose both money and trust due to food fraud, especially for non-Swedish meat relabelled as Swedish. Most fraud remains undetected. A recent analytical development, Rapid …

Wheat bran is the largest by-product of wheat flour production with approximately 300,000 tonnes in Sweden. Bran is mainly used in animal feed, as human digestion is not fully able to absorb it. Wheat bran contains valuable biomolecules, such as dietary fiber (arabinoxylans, AX) and phenolic …

The purpose of this project is to define the amount of slaked lime needed for a given clay soil. We hypothesise that the amount of slaked lime needed for minimal phophorus loss is dependent on the clay content of the soil. The study will be conducted in a field with a drainage system and measuring …

Competing unshod is an important issue for the Swedish harness industry. There is a general opinion that performance may increase significantly but it does not always work. The reason for failure may be disturbed locomotion “balance” of the horse or due to pain from the hooves. This is obviously …

Resistance to anthelmintic drugs is a threat to equine welfare. Like antibiotics, is restrictive use of anthelmintics necessary to retain their effectivity. Thus, targeted selective treatment, based on individual deworming, was introduced a decade ago. However, we have shown that the prevalence of, …

Increased production and export of products with high added values, e.g. long-ripened hard cheeses, are considered important steps for a positive development of the Swedish dairy sector. Increased investment in Swedish premium cheese will, however, require increased volumes of high quality raw milk …
