For decades scientists have speculated that rising global temperatures might alter the ability of soils to store carbon, potentially releasing huge amounts of carbon into the atmosphere and triggering...
Lysimetric research of nutrient losses from organic fertilizers
organic fertilizer nitrates nitrites ammonium ions lysimetric water

Dissolved organic carbon (DOC) losses from tile drains are an underquantified portion of the terrestrial carbon cycle. This is particularly important in the eastern corn belt where tile drainage domin...
Phosphorus losses from a subdrained clayey soil as affected by cultivation practices
Phosphorus eutrophication conservation tillage moldboard ploughing runoff drainage

Conservation tillage practices are included in the Finnish Agri-Environmental Program as phosphorus (P) loss control measures, but only few experiments have been performed to check their effectiveness...
Influence of EU policy on agricultural nutrient losses and the state of receiving surface waters in Finland
Agriculture eutrophication nutrients water quality runoff rivers lakes estuaries climate change

Reduced tillage: Influence on erosion and nutrient losses in a clayey field in southern
erosion nitrogen phosphorus losses from soil tillage water
2010/8/13
Reduced tillage was compared with traditional ploughing in terms of erosion and phosphorus (P) and nitrogen (N) losses in an experimental field in southern Finland. One part of the field has been plou...
