A comparison of nitrogen and carbon reserves in acid sulphate and non acid sulphate soils in western Finland
Agricultural and Food Science : 1 (MTT Agrifood Research FinlandThe Scientific Agricultural Society of Finland, 2005)Tavanomaisten viljelymaiden hiilestä ja typestä valtaosa on sitoutuneena muokkauskerroksen orgaaniseen ainekseen. Happamissa sulfaattimaissa on melko runsaasti orgaanista ainesta myös muokkauskerroksen alapuolella. ... -
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, ... -
Classification of acid sulphate soils of Finland according to Soil taxonomy and the FAO/Unesco legend
Agricultural and Food Science in Finland : 3 (Agricultural Research Centre of FinlandThe Scientific Agricultural Society of Finland, 1997)Suomessa luokitellaan happamiksi sulfaattimaiksi sellaiset maat, joissa kuivaamattomasta näytteestä mitattu maaprofiilin minimi-pH on alle 5 ja maan hapetus- pelkistyspotentiaali ensin nousee ja sitten laskee mentäessä ... -
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 ... -
Stream plant chemistry as indicator of acid sulphate soils in Sweden
Agricultural and Food Science : 1 (MTT Agrifood Research FinlandThe Scientific Agricultural Society of Finland, 2005)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 sulphate (AS) soils ... -
Successive alkalinity producing system for the treatment of acid sulphate soil runoff: preliminary results of a field trial
Agricultural and Food Science : 1 (MTT Agrifood Research FinlandThe Scientific Agricultural Society of Finland, 2005)Artikkelissa on käsitelty happamien sulfaattimaiden kuivatusvesien käsittelyyn suunnitellun koelaitoksen toimintaa kahden ensimmäisen käyttövuoden ajalta. Koelaitos on perustettu Ilmajoelle Rintalan pengerrysalueelle. ...
