An analytical procedure for determination of sulphur species and isotopes in boreal acid sulphate soils and sediments
Agricultural and Food Science : 1 (MTT Agrifood Research FinlandThe Scientific Agricultural Society of Finland, 2005)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 acid volatile sulphide, ... -
Assessment of aquatic pollution, remedial measures and juridical obligations of an acid sulphate soil area in western Finland
Agricultural and Food Science : 1 (MTT Agrifood Research FinlandThe Scientific Agricultural Society of Finland, 2005)Reclaiming of Holocene sulphide-bearing sediments, widespread in the coastal areas of Finland, has enabled oxidation of sulphides to a depth of 1 3 m and the subsequent development of acid sulphate soils (pH < 4). This ... -
Concentration levels and spatial distribution of sulphur and metals in fine-grained sediments in western Finland
Agricultural and Food Science : 1 (MTT Agrifood Research FinlandThe Scientific Agricultural Society of Finland, 2005)On the coastal plains of Finland, widespread Holocene marine and lacustrine sediments have developed into acid sulphate soil as a result of extensive artificial drainage for agricultural purposes. This has caused a variety ... -
Hydrochemistry of rivers in an acid sulphate soil hotspot area in western Finland
Agricultural and Food Science : 1 (MTT Agrifood Research FinlandThe Scientific Agricultural Society of Finland, 2005)During heavy rains and snow melting, acid sulphate (AS) soils on the coastal plains of Finland are flushed resulting in discharge of acidic and metal-rich waters that strongly affect small streams. In this study, the ... -
Measured and simulated effects of sophisticated drainage techniques on groundwater level and runoff hydrochemistry in areas of boreal acid sulphate soils
Agricultural and Food Science : 1 (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska FairbanksMTT Agrifood Research FinlandThe Scientific Agricultural Society of Finland, 2005)To abate the environmental problems caused by the severe acidity and high metal concentrations in rivers draining acid sulphate (AS) soils of Western Finland, control drainage (CD) and lime filter drainage (LFD), and their ... -
Metal concentrations in oats (Avena sativa L.) grown on acid sulphate soils
Agricultural and Food Science : 1 (MTT Agrifood Research FinlandThe Scientific Agricultural Society of Finland, 2009)The aim of the study was to investigate the impact of soil chemistry on the concentrations of Co, Ni, Zn, Mn, Cu and Fe in oats (Avena sativa L. cv. Fiia) grown on Finnish acid sulphate (AS) soils with varying geochemical ... -
pH of streams in western Finland - a perspective from the Middle Ages into the mid 21st century
Agricultural and Food Science : 1 (MTT Agrifood Research FinlandThe Scientific Agricultural Society of FinlandMTT Agrifood Research FinlandThe Scientific Agricultural Society of Finland, 2005)In the central parts of western Finland, many streams are severely acidified as a result of land-use activities on overburden (soils) capable of producing and ultimately releasing extreme acidity. Consequently, the extent ... -

Sources of acidity and metals in a stream draining acid sulphate soil, till and peat, western Finland, revealed by a hydrochemical and sulphur isotope study
Agricultural and Food Science : 1 (MTT Agrifood Research FinlandThe Scientific Agricultural Society of Finland, 2005)The main aim of this study was to determine, during extreme hydrological conditions, the source(s) of acids, sulphate and metals (alkali and alkaline earths) in the Munsala stream (western Finland) draining mainly acid ...
