Conventional technology is virtually unable to measure complete GHG budgets of drained organic soils, which may provide misleading results. So, global estimates of GHG emissions are based on coarse assumptions that don’t take into account the complexity of agroecosystems. Better data are needed for evidence-based rulings on mitigation. By newly developed Relaxed Eddy Accumulation (REA) systems we will study complete, continuous GHG budgets (H2O, CO2, CH4, N2O, NH3) from 3 pairs of organic agricultural fields with contrasting peat layer depth and cultivation. This will shed new light on the climate impact of cultivated organic soils and the importance of site-specific conditions and management. High time resolution enables process studies to reveal key parameters and mechanisms that control GHG fluxes in the soil-plant-atmosphere system, which will significantly improve simulation models. This will notably improve GHG reporting, climate modeling, and the base for mitigation strategies.
Med konventionell mätteknik är det praktiskt taget omöjligt att mäta fullständiga växthusgasbudgetar från dränerad organogen mark, vilket kan ge missledande resultat. Därför baseras globala skattningar av växthusgasutsläpp idag på grova antaganden som inte tar hänsyn till agro-ekosystemens komplexitet. Bättre data behövs för evidensbaserad klimatpolitik. Genom nyutvecklade Relaxed Eddy Accumulation (REA) system kommer vi under 3 år att studera fullständiga, kontinuerliga växthusgasbudgetar (H2O, CO2, CH4, N2O, NH3) av 3 par av organogena åkrar som skiljer sig avsevärt m.a.p. torvlager och odling. Detta ger nya insikter i klimateffekterna av jordbruk på organogen jord. Hög tidsupplösning möjliggör även processtudier som avslöjar nyckelmekanismer och parametrar som styr växthusgasflöden i mark-växt-atmosfärssystemet. Detta förbättrar simulationsmodeller och därmed växthusgasrapportering, klimatmodellering, och beslutsunderlag för klimatåtgärder.

Humus is an important indicator of soil quality and soil organic carbon (SOC) sequestration is a cost-effective measure to reduce the climatic impact of food production systems. The national soil-monitoring program (SMP) show an upward trend in SOC during the past 20 years, mostly attributed to an …

Cannabinoids have potential to induce analgesia and muscle relaxation which would be beneficial for equine practice. Today there is no drug labelled for veterinary use containing these cannabinoids, but there are some herbal oil products which unofficially have been reported to be used in horses, …

Worm infections in free-range layers are increasingly causing health problem in the poultry industry. Despite this, there are knowledge gaps about how worms are detected in living laying hens and on methods for how they can be controlled in modern free-range housing systems. The objectives of the …

Correct assessment of hind limb lameness is a challenge, also for most experienced vets. This causes incorrect diagnoses and faulty treatment interventions which lead to unnecessary suffering for the horses and an unnecessary financial burden for owners and insurance companies. The aim of this …

The carbon footprint for ruminants is high compared to other food products of animal origin but grazing animals such
as beef and lamb have other positive effects on the environment such as increased biodiversity and carbon
sequestration. Beef- and lamb producers need clear guidelines on how to …

The project aims to lay the foundation for genomic selection in Swedish beef cattle populations. Genomic selection has revolutionized animal breeding and much increased genetic progress in e.g. dairy cattle. Improved animal breeding increases production efficiency and genomic selection enables …

Grass for grazing or forage production contains variable amounts of carbohydrates, which often are described as the good (fiber), the bad (sugar) and the ugly (fructans) in relation to prevention, and development of diseases like insulin resistance and laminitis. There is a large variation in …

Knowledge of disease development in wheat is a prerequisite for good advice on economically and environmentally
adapted control strategies. This project is based on knowledge from a previous SLF project about molecular detection
and spore traps, which showed that the different spore traps catch …

The goal is models for translating satellite data from the time of supplementary fertilisation directly to nitrogen (N) recommendation maps. The crops are winter wheat (Triticum aestivum L.) and malting barley (Hordeum vulgare L.). A new multispectral camera for drones, with nine bands of the same …

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 …
