Measured and simulated effects of sophisticated drainage techniques on groundwater level and runoff hydrochemistry in areas of boreal acid sulphate soils
(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 ...
A comparison of nitrogen and carbon reserves in acid sulphate and non acid sulphate soils in western Finland
(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
(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, ...
Hydrochemistry of rivers in an acid sulphate soil hotspot area in western Finland
(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
(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
(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. ...
