Hitaasti typpeä vapauttavan ureaformaldehydin vaikutuksista puuston kasvuun, maaperään ja ympäristöön
(Finnish Society of Forest Science, 2020)
Suomessa perustettiin 1970-luvulla kenttäkokeita hidas- ja nopealiukoisten typpi- fosfori- ja kaliumlannoitteiden vertailua varten. Hitaasti typpeä vapauttavaa amerikkalaista ureaformaldehydilannoitetta verrattiin ...
Comparison of granulated and loose ash in fertilisation of Scots pine on peatland
(Finnish Society of Forest Science, 2020)
The effects of wood ash fertilisation on tree nutrition and growth on forested peatlands has been studied using loose ash, but in practice, ash fertilisation is done almost exclusively with granulated ash. In this study, ...
Assessing local trends in indicators of ecosystem services with a time series of forest resource maps
(Finnish Society of Forest Science, 2020)
Since the 1990’s, forest resource maps and small area estimates have been produced by combining national forest inventory (NFI) field plot data, optical satellite images and numerical map data using a non-parametric k-nearest ...
The effect of winter weather on timber truck tare weights

From a rare inhabitant into a potential pest – status of the nun moth in Finland based on pheromone trapping
(Finnish Society of Forest Science, 2020)
Forests are being hit by climate change in various ways. This includes abiotic factors such as droughts, but also an increased risk of damage caused by biotic agents such as insects. There are numerous examples from cases ...
Comparison of planting success in one-year-old spring, summer and autumn plantings of Norway spruce and Scots pine under boreal conditions
(Finnish Society of Forest Science, 2020)
Stand-level mortality models for Nordic boreal forests
(Finnish Society of Forest Science, 2020)
New mortality models were developed for the purpose of improving long-term growth and
yield simulations in Finland, Norway, and Sweden and were based on permanent national forest
