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 station for sampling runoff and leachates. We also conduct investigation in the laboratory, where we test five soil texture classes (10-15%, 20-25%; 30-35%, 40-50%, > 50 %). This test will help us to develop a simple decision support tool for calculating the amount of slaked lime required to amend clay soils depending on their clay content.The study will be evaluated by measuring soil aggregate stability and by determining phosphorus content in leachates and runoff.
Detta projekt syftar till att fördjupa befintlig kunskap om strukturkalkning. Hypotesen är att mängden släkt kalk som behövs för minimalt fosforläckage beror på jordens lerhalt. I studien ingår fältförsök och laboratorietest. Fältförsöket ger oss möjlighet att utvärdera strukturkalkningens nytta för reducering av fosforutlakning. Laboratorietest på olika jordar hjälper oss för att bygga en beräkningsmodell för att bestämma dosering av strukturkalk för olika lerklasser. För detta testar vi fem olika lerklasser (10-15%, 20-25%; 30-35%, 40-50%, > 50 %). Studien utvärderas genom att mäta aggregatstabilitet och fosforförluster med läckage och ytavrining.

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 …
