Effects of long-term fertilisation on soil properties in Scots pine and Norway spruce stands

Autor: Saarsalmi, Anna, Tamminen, Pekka, Kukkola, Mikko

Publikováno v: Silva Fennica, Vol 48, Iss 1 (2014)

The response of surface soil after 45- to 52-years to repeated nitrogen and phosphorus fertilisation was studied. This study included 30 factorial experiments established in young (5- to 30-year-old) stands using plots of 900 m, on average, and by ra

Temporal trends in chemical parameters of upland forest soils in southern Finland

Autor: Tamminen, Pekka, Derome, John

Publikováno v: Silva Fennica, Vol 39, Iss 3 (2005)

Changes in chemical soil properties during periods of 12 to 28 years were studied in 54 stands in southern Finland. Relative slopes (%/year) were calculated for the changes in soil variables in order to utilise all the sampling occasions (2â6) cover

Boron, phosphorus and nitrogen fertilization in Norway spruce stands suffering from growth disturbances

Autor: Saarsalmi, Anna, Tamminen, Pekka

Publikováno v: Silva Fennica, Vol 39, Iss 3 (2005)

Growth disturbance symptoms typical of B deficiency have been reported on Norway spruce (Picea abies (L.) Karst.) trees in many parts of eastern Finland. In order to test the B deficiency hypothesis and explore the possibilities of curing the disturb

Autor: Kauppi, Pekka, Hänninen, Pekka, Henttonen, Helena, Ihalainen, Antti, Lappalainen, Eino, Posch, Maximilian, Starr, Michael, Tamminen, Pekka

Publikováno v: Silva Fennica, Vol 31, Iss 1 (1997)

The carbon reservoir of ecosystems was estimated based on field measurements for forests and peatlands on an area in Finland covering 263,000 km and extending about 900 km across the boreal zone from south to north. More than two thirds of the reserv

Bulk density of forested mineral soils.

Autor: Tamminen, Pekka, Starr, Michael

Publikováno v: Silva Fennica, Vol 28, Iss 1 (1994)

Relationships between bulk density and organic matter (OM) content, textural properties and depth are described for forested mineral soils from Central and Northern Finland. Core samples were taken of 0â5, 30â35 and 60â65 cm layers at 75 plots. Th
