A main challenge for regions with intensive livestock production is phosphorus (P) surplus on farms, resulting in low P use efficiency and losses to waters. The project will provide solutions to increase P recycling from animal manure. This will decrease our dependency on imported P fertilizers, reduce the environmental load and allow for economic development on farms. We will study a scenario where a biogas plant is used as a node to process and upgrade the digestate for optimizing redistribution of nutrients to arable land. The liquids are returned to nearby land and the solids, with high P content, can be transported further away. We will collaborate with More biogas in Kalmar for substrate production. Our studies include 1)A field study of the fertilizer value of the liquid fraction, also with the N2 applied method for improved N content, 2)Scenarios for optimal redistribution of NPK to farms at N. Öland, and 3) Development of a method for regional planning of manure P recycling
En stor utmaning för hållbar utveckling i områden med intensiv djurproduktion är överskott av fosfor (P) på gårdar, vilket innebär dåligt resursutnyttjande och risk för läckage till vattenmiljön. Projektet bidrar till förbättrat kretslopp för fosfor i jordbruket, vilket minskar gårdars miljöpåverkan och ger möjlighet till utveckling. Vi studerar biogasanläggningen som nod för optimerad återföring av växtnäring till odlingsmark. Om rötrester fas-separeras och uppgraderas kan den flytande kväverika fraktionen återföras i närområdet, medan den fasta fosforrika fraktionen kan transporteras längre. Vi samarbetar med projekt på More biogas i Kalmar där teknik i pilotskala byggs. Vi utför 1) Fältstudier av växtnäringsvärdet hos den flytande fraktionen, också med den nya metoden N2 applied som höjer kväveinnehållet ytterligare, 2) Scenarier för optimerad återföring av NPK till mark runt en planerad anläggning på Öland och 3) Utveckling av metod för optimerad fosforåterföring i regional skala

Fruit tree canker, caused by the fungus Neonectria ditissima, has become a threat for Swedish apple production. No efficient protective measures are available and no complete genetic resistance is known in apple. However, apple genotypes differ in the level of partial resistance which must be fully …

Healthy seeds are a prerequisite for sustainable food systems. The seed-borne plant disease, common bunt (CB) in wheat, caused by the fungi Tilletia tritici and T. laevis, is a major problem in agriculture. Efficient chemical seed treatments exist, but it is often difficult to keep up with autumn …

Colibacillosis is a common disease in poultry and includes both local and systemic infections. Increased knowledge is necessary for development of effective methods to prevent disease, such as improved management routines, modification of environment, and vaccine development. The first study (WP1) …

A major challenge facing agriculture is handling water excess and deficit exacerbated by climate change, while reducing eutrophication. Controlled drainage (CD) has the potential to address these issues and improve yield stability. Despite CDs clear benefits and state subsidies for CD installation, …
