To grow with reduced use of glyphosate is of great concern driven by the requirements for integrated pest management, the risk of herbicide resistance and a potential coming ban on glyphosate. It requires balancing between environmental effects and impact on yield and economy. The project's goal is to develop strategies for successful mechanical termination of grass-clover leys without glyphosate, and without the risk of increased nutrient leaching. We collaborate with a Swedish trial series to deepen the knowledge about plant nutrient management and water quality. This is done in a field facility with separately tile-drained plots on a sandy soil in southern Sweden, in 2023 and 2024 (4 replicates). Factors investigated are method, intensity and time of tillage before ploughing in September, and also time of harvest. A control with use of glyphosate is included. Leaching of nitrogen and phoshporus, soil mineral nitrogen, effects on weeds and residual effect on wheat are investigated
Att odla med minskat beroende av glyfosat är en stor fråga inom jordbruket. Den drivs av krav på integrerat växtskydd, risk för resistens hos ogräsen och utfasning av glyfosat. Olika lösningar innebär avvägningar mellan olika typer av påverkan på miljö, skörd och ekonomi. Projektets mål är att ta fram kunskap om strategier för effektivt mekaniskt vallbrott utan glyfosat, och utan risk för ökat växtnäringsläckage. I projektet utgår vi från en försöksserie inom Sverigeförsöken (L2-6500) och fördjupar studierna till att även omfatta växtnäringshushållning och vattenkvalitet. Det görs i specialdränerade försöksrutor på sandjord vid Lilla Böslid, Halland under 2023 och 2024 med fyra upprepningar. Faktorer som undersöks är metod, intensitet och tidpunkt för ytlig mekanisk bearbetning före plöjning i september, tillsammans med skördetidpunkt. Kontrolled med glyfosat ingår. Utlakning av kväve och fosfor, markmineralkväve, effekt på vallsvål och ogräs samt efterverkan på vetegröda undersöks

Effective communication between driver and horse via rein signals is essential for safety and horse welfare. Good driveability should at best reflect the absence of unnecessary harsh equipment. Yet, many trotters suffer from mouth lesions but associations with equipment, rein tension and motion …

Human athletes that perform strenuous exercise in cold climates have a high prevalence of chronic airway inflammation and airway hyper-reactivity. Cold weather exercise can also cause inflammation in equine airways. The Swedish Animal Welfare Act and the equine sport industry have regulations for …

Racing unshod improves the speed, but not all horses have sufficient hoof quality to run barefoot repeatedly without risking health problems. If measures of the ability to race barefoot based on routinely recorded data can be used as a genetic selection tool, it will improve animal health and …

The work in horse stables is commonly characterised by heavy and monotonous work, a low degree of
mechanisation and often outdated and worn facilities, and studies have shown a high prevalence of musculoskeletal

The amount and nutritive content of forages has major impact on equine behaviour, health, and disease. In the Nordic countries, forages for horses consist almost exclusively of grasses, and to a limited extent of legumes. Legumes contain more crude protein than grasses, hence locally produced …

The project aims to study the long-term effect of structure liming, and to test if minimum tillage can prolong the duration of this effect. The hypothesis is that structure liming effects diminish over time, but by minimizing soil tillage we can prolong this effect. Studies will be performed in six …

Soil organic carbon is an important factor for soil health and productivity. Soil carbon sequestration (SCS) also plays a crucial role in meeting the climate goals. For that purpose, catch- and cover crops are identified as a cost-effective management practice that combines SCS with other ecosystem …

The risk of soil compaction is high in Sweden, as soils are often wet during field operations and because heavy machinery is used. The predicted increase in precipitation and increase of extreme weather events with heavy rainfall will potentially increase this risk, indicating a need for a reliable …
