(MTT Agrifood Research FinlandThe Scientific Agricultural Society of Finland, 2006)
Karkeille hietamaille syntyneet podsolit ovat Suomen kehittyneimpiä maannoksia. Niitä tutkimalla saadaan uutta tietoa tämän koko pohjoisella havumetsävyöhykkeellä yleisen maannostyypin kehittymiseen johtaneista prosesseista, ...
Nutrient uptake and biomass accumulation for eleven different field crops
(MTT Agrifood Research FinlandThe Scientific Agricultural Society of Finland, 2009)
Tutkimuksen astiakokeessa kasvatettiin yhtenäisissä oloissa Suomessa vähän viljeltyjä, mutta ominaisuuksiltaan mielenkiintoisia viljelykasveja. Kasvit olivat öljyhamppu, (Cannabis sativa L.), kinua (Chenopodium quinoa ...
Concentration levels and spatial distribution of sulphur and metals in fine-grained sediments in western Finland
(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 ...
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 ...
pH of streams in western Finland - a perspective from the Middle Ages into the mid 21st century
(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 ...
