Fine root development and mycorrhization in Norway spruce stands one year after fertilization with potassium sulphate and wood ash
forest fertilization fine root ectomycorrhizal fungi
2016/1/29
We compared the effects of forest fertilization with wood ash and potassium (K) sulphate on growth and mycorrhizal colonization of fine roots and on other soil microorganisms in Norway spruce (Picea a...
Successive alkalinity producing system for the treatment of acid sulphate soil runoff: preliminary results of a field trial

2010/8/11
Results from the biogeochemical mapping (roots of aquatic plants and Fontinalis antipyretica) conducted by the Geological Survey of Sweden (SGU) reflects the metal load of surface waters draining acid...
An analytical procedure for determination of sulphur species and isotopes in boreal acid sulphate soils and sediments
sulphur species sulphur isotopes analytical scheme acid sulphate soils sediment
2010/8/11
An analytical scheme suitable for boreal acid sulphate (AS) soils and sediments was developed on the basis of existing methods. The presented procedure can be used to quantify and discriminate among a...
A comparison of nitrogen and carbon reserves in acid sulphate and non acid sulphate soils in western Finland
carbon nitrogen nitrification mineralization soil organic matter acid sulphate soils subsoil drainage humus
2010/8/11
Previous studies suggest that nitrogen (N) loads from acid sulphate soil (AS soil) catchments in Finland are higher than those from other agricultural catchments. This study seeks to explain this diff...
