This study was conducted to analyse the changes in the nutritional status of Scots pine (Pinus sylvestris) that happen between autumn (September-October) and the following winter (December-March); and determine whether needle samples taken already in September or October give accurate results...

Cultivation experiments with Acorus calamus L. and Salix myrsinifolia Salisb. were performed during 2000-2004 in two cat-away peatlands at Pakinsuo mire, Juva (61°50′N/27°52′E) and Kovalansuo mire, Mikkeli (61°46′N/27°18′E). Comparison experiment for Salix was carried out on mineral soil as well at ...

The first part of this book describes the spread of potato from South America to Europe and the Nordic countries [Scandinavia], and presents the cultivation and breeding history of potato in each of the Nordic countries. At the end of part one, advice on the practical cultivation of potatoes in...

Lingonberry (Vaccinium vitis-idaea) is the most important wild berry species of the European boreal region. Organic mulch is necessary for lingonberry to grow successfully on arable soils. Organic mulch, preferably pine bark or other forest products, combined with the appropriate herbicide...

The roots of 3-yr-old Pinus sylvestris seedlings were exposed to a temperature of 32°C and relative humidity of 40-50% for 85, 155 and 270 minutes, corresponding to accumulated water pressure deficits of 24, 47 and 91 mbar/h, respectively. Thereafter, seedlings were grown for 65 days at soil...

The effects of refertilization and growing density on the soil and tree nutrition, root penetration and growth of Scots pine (Pinus sylvestris) stands were studied in a cutaway peatland area with deep peat layers in Finland. The fertilization treatments were control, N₁₉₇₅ + PKB₁₉₈₅ and PK₁₉₇₅ +...

Soil chemistry and plant composition were analysed in Pinus sylvestris and Betula pendula plantations on old fields in W. Finland.

A natural understorey of Norway spruce (Picea abies) often develops under birch (Betula pubescens) on oligo-mesotrophic peatlands, but spruce can also be planted on these sites. The effects of fertilizer application and the density of the pubescent birch nurse crop on the height growth and needle...

Variation in nutrient concentrations in Scots pine (Pinus sylvestris) needles in relation to crown position and needle age was examined at two drained peatland fertilizer experiments in Finland. Samples were taken from plots which had received NPK fertilizers and from sites which had received only...

Liming (with applications of 1000 to 8000 kg/ha) had no long-term (1929-1985) effect on the growth of Scots pine (Pinus sylvestris) on drained oligotrophic peatlands. Liming plus application of NPK fertilizer had a variable effect on the growth of the stands. Both liming alone and liming plus NPK...
