Cypress (Cupressus funebris Endl.) is a major tree species planted for forestland restoration in low-fertility soil and in areas where rocky desertification has occurred. Calcium (Ca) fertilizer can a...
After 26 years, the world’s longest-running experiment to discover how warming temperatures affect forest soils has revealed a surprising, cyclical response: Soil warming stimulates periods of abundan...
A legacy of acid rain has acidified forest soils throughout the northeastern US, lowering the growth rate of trees. In an attempt to mitigate this trend, in 1999 scientists added calcium to an experim...
Relic karstic soils in nine localities in the Dinaric Karst in Slovenia, five localities in the Moravian Karst and four localities in the Bohemian Karst were sampled for soil scientific, mineralogical...
Forest ecosystems of the Krušné hory Mts. affected by long-term air pollution were finally disintegrated. The tree species composition has been changed in ecosystems disturbed in this way. Liming...
Based on a greenhouse experiment, we evaluated nitrogen availability in the surface mineral layer of soil under various deciduous forest stands by analysing the following soil characteristics: total o...
The exact data from the field of soil mechanics from specific forest stands exposed to forestry mechanization operation were obtained. Field surveys were performed on four study plots within the K"...
The paper discusses possibilities of using the portable falling weight deflectometer to measure the bearing capacity and compaction of forest soils. Within the study, measurements were made using manu...
This paper documents the development of soil conditions in the set of 32 permanent research plots in the Krkonoše (Giant) Mts. These plots represent an altitudinal gradient covering the ecosystem...
A pedological survey was carried out in a spruce monoculture, beech stand, and in a mixed stand at a field research station in R醞ec-N靘鑙ce of the Institute of Forest Ecology (IFE), Mendel University of...
The purpose of the study was to assess, in respect of selected physical properties, the reclamation of the northern slope of the outside spoil bank of the Belchatów brown coal mine by reforestation ca...
The paper presents the results of relatively long-term research focused on spoil bank revitalization pro-cesses in the North Bohemian Brown Coal Basin after the first three years of observations. The ...
Toxic pollution of soils is a major environmental problem in the Czech Republic. Most contemporary remediation approaches do not provide acceptable solutions. For environmental clean-up, the use of ...
This study aims to investigate the changes in isotope ratios in foliage and soils of two Norway spruce (Picea abies [L.] Karst.) forests greatly differing in their atmospheric N deposition and climati...
Restoration of forest soil character after the change of agricultural land use has not been studied yet despite the large areas reforested since the late 40ies of the last century. This process takes ...
