Nitrogen (N) gross balance is one of the indicators designed for following developments in agriculture in the European Union. A nutrient surplus occurs when the quantity of a nutrient applied in ferti...
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
2010/8/9
In Finland, the first large-scale efforts to control nutrient loading from agriculture got under way with the introduction of the EU Agri-Environmental Program in 1995. We examined whether these effor...
Water repellency of clay, sand and organic soils in Finland
Water repellency hydrophobicity infiltrometer ethanol clay soil sand soil organic soil boreal climate zone
2010/8/9
Water repellency (WR) delays soil wetting process, increases preferential flow and may give rise to surface runoff and consequent erosion. WR is commonly recognized in the soils of warm and temperate ...
Effects of repeated phosphorus fertilisation on field crops in Finland 2.Sufficient phosphorus application rates on silty and sandy soils
acid ammonium acetate method soil test P soil phosphorus sufficient P fertilisation
2010/8/10
In order to update fertilisation recommendations for Finnish silty and sandy soils, the effects of repeated phosphorus (P) fertilisation on the yields of cereals, grasses and other crops were measured...
Assessing the recreational demand for agricultural land in Finland

2010/8/10
It is widely assumed that the scenic attractiveness and other public good aspects of agricultural land can be utilized as a source of livelihood in rural areas in the form of recreation and tourism. I...
Effects of repeated phosphorus fertilisation on field crops in Finland 1.Yield responses on clay and loam soils relation to soil test P values
Acid ammonium acetate method optimal soil test P soil acidity soil phosphorus
2010/8/10
In order to update phosphorus (P) fertiliser recommendations for the Finnish clay and loam soils enriched with applied P, the effects of repeated P fertilisation on the yields of cereal and other crop...
Formation of a cultivated spodosol in east-central Finland
podzolization soil morphology soil mineralogy biotite soil classification
2010/8/10
The processes involved in Spodosol (Podzol) formation are still being debated. The pedogenic processes in a Spodosol, 10,700 years-old, at Sotkamo that has been cultivated for about 50 years were stud...
A comparison of nitrogen and carbon reserves in acid sulphate and non acid sulphate soils in western Finland
carbon nitrogen nitrification mineralization soil organic matter acid sulphate soils subsoil drainage humus
2010/8/11
Previous studies suggest that nitrogen (N) loads from acid sulphate soil (AS soil) catchments in Finland are higher than those from other agricultural catchments. This study seeks to explain this diff...
Phosphorus status of diverse soils in Finland as influenced by long-term P fertilisation 2.Changes of soil test values in relation to P balance with references to incorporation depth of residual and freshly applied P

2010/8/13
Fertilising with phosphorus (P) ensures continuous supply of an essential growth factor as necessary for productive and sustainable agriculture. The amounts of P required to attain and maintain an ade...
On diversity effects of alternative agricultural policy reforms in Finland: an agricultural sector modelling approach
agricultural policy reform agricultural sector model biodiversity landscape diversity land use nutrient balances pesticides production intensity
2010/8/13
The European Union has decided to reform its agricultural policy and decouple Common Agricultural Policy support partially from production. The aim of this study is to predict the diversity effects of...

Acetate method phosphorus Olsen P P saturation index secondary inorganic P total P water extractable P
2010/8/13
The native reserves of phosphorus (P) in Finnish soils are sizeable but poorly available to plants. The P status has been generally poor, but large rates of P applied since the 1940s have substantiall...
Effect of liming on yield and quality of peppermint and Sachalin mint in fine sand soil of Northern Finland
Lamiaceae lime Mentha arvensis var. sacchalinensis Mentha x piperita menthone
2010/8/13
Soil acidity commonly limits plant production in the fine sand soil of Northern Finland, which often has a low pH (5.5-6.5) and contains low levels of Ca and Mg. The effect of five liming (10% Mg and ...
