The project “Climate smart Agriculture on Organic Soils” (CAOS) aims to generate the knowledge to design climate smart agricultural systems for organic soils adapted to the diverse regional conditions of Europe. Drought spells and extreme precipitation events are likely to increase in a changing climate and endanger the stability of agricultural production. Drainage fosters mineralization of organic soils and deteriorates the soil and water quality, inducing a high risk of crop failure. Due to subsidence, the remaining lifetime of such systems is limited by the (rising) sea water level and underlying low-quality soil layers. Organic soils are the hotspots of vulnerability, adaptation needs and greenhouse gas (GHG) emissions in temperate and boreal Europe. CAOS will provide and distribute evidence that climate smart management improves yield stability and quality as well as resilience to climate change while providing strong GHG mitigation and improved soil and water quality. We expect that the strong potential for adaptation to increased climatic variability on farmed organic soil will facilitate mitigation of the largest GHG source from agriculture in Central and Northern Europe. In Estonian study sites in abandoned peat exctraction areas we study the effect of reed canary grass (Phalaris arundinacea) cultivation on GHG emission and carbon losses mitigation.
