(Taylor & Francis Group, 1987-01-01)In this article, an engineering approach is used to derive the access cost function for roundwood in northern Sweden. This approach can make use of detailed biological, technological and economic information and can give ...
-
(Taylor & Francis Group, 1987-01-01)Exchangeable Al and acidity of Swedish beech (Fagus sylvatica L.) forest soils are documented and discussed on the basis of known changes in soil chemical properties during recent decades. It is concluded that the pH and ...
-
(Taylor & Francis Group, 1993-01-01)The acidification status of forest soils in seven counties in Norway was studied on the basis of chemical analysis of 3 000 humus samples collected in a regular grid pattern. In samples with more than 70% organic matter ...
-
(Taylor & Francis Group, 1989-01-01)The quantity and quality of throughfall and soil leachate were measured in 1983–1985 in three Scots pine stands of different age situated in Ilomantsi, eastern Finland. Soil leachate was collected using percolation lysimeters. ...
-
(Taylor & Francis Group, 1991-01-01)The soil acidity of four coniferous sites, two in S Sweden and two in N Sweden, were studied 7–9 years after clear‐felling. Each site had three different slash treatments; (a) all slash harvested, (b) only needles remaining, ...
-
(Taylor & Francis Group, 1988-01-01)The chemical status within a subset of Swedish forest soils representing Spodosols and acid Entisols and Inceptisols at mesic sites is reported. Three regions which differ in climate and deposition, southwestern (SW), ...

(Taylor & Francis Group, 1992-01-01)In this paper, we report the results of a comparison of soil solution and exchangeable cation data from a laboratory experiment with those predicted by MIDAS, a simple soil acidification model based on Gaines‐Thomas cation ...
-
(Taylor & Francis Group, 1996-01-01)A method for estimating the economic loss in timber production resulting from extending the rotation age was studied. Basically, optimal rotation age depends on the stated objectives. If the objective comprises only timber ...
-
(Taylor & Francis Group, 1995-01-01)The history of a pine dominated (Pinus sylvestris L.) forest stand in northern Sweden was documented by applying dendrochronological crossdating technique on stumps, down logs and living trees within a small (0.1 ha) sample ...
-
(Taylor & Francis Group, 1993-01-01)A model of tree diameter growth during the growth season was developed to standardize the forest data from different inventory dates. A diameter growth index is defined and its relation with the number of growing days is ...
-
(Taylor & Francis Group, 1988-01-01)Fertilization is modelled on the basis of two concepts, nutrient flux density in the soil (amount of nutrient available per unit of soil and unit of time) and nutrient productivity (growth rate per unit of nutrient in ...
-
(Taylor & Francis Group, 1987-01-01)Over a period of five months, the forest floor of a coniferous stand was irrigated 20 times with a total of 100 mm of artificial rain in addition to the normal precipitation (302 mm). The experiment was made with a fully ...
-
(Taylor & Francis Group, 1992-01-01)A method using sample plots with “fixed number of stems, random circular plot size”; in the stand‐description phase was studied both theoretically and empirically in several regards; it was also developed for practical ...
-
(Taylor & Francis Group, 1992-01-01)The defence of Norway spruce against a combined attack of the bark beetle Ips typographus and its associated blue‐stain fungi is based upon a) constitutive resin stored in ducts of the bark and sapwood, and b) induced ...
