2024/5/10
Moso bamboo (Phyllostachys edulis) is China's most important economic bamboo species. With a continuous decline in the value of its shoots and timber and an increase in affiliated labor and production...
Root functional traits mediate rhizosphere soil carbon stability in a subtropical forest（图）
Root functional traits subtropical forest
2023/6/2
Plants can be classified as either resource-acquisitive or resource-conservative strategies based on their root traits. Compared with conservative trees, acquisitive trees produce larger amounts of re...

2017/6/26
Horizontal alignment and cross section characteristics of a skid trail in a ground-based skidding system including curves, wheel ruts and cross slope can impact on the forest soil. In this study the m...
Production and soil restoration effect of pioneer tree species in a region of allochthonous Norway spruce dieback
forest transformation regeneration methods birch aspen wood production soil chemistry
2017/4/6
The paper analyses the growth, structure, production and soil chemistry of different tree species stands 20 years after allochthonous spruce dieback. The experiment was carried out at lower altitudes ...
Detection of the effects of management and physical factors on forest soil carbon stock variability in semiarid conditions using parametric and nonparametric methods
soil organic carbon CART modelling, neural networks
2015/11/26
Forest soils in western parts of Iran are being degraded by inappropriate management. The soil organic carbon (SOC) stock was dominantly affected by this type of degradation. On the other hand, SOC is...
Effects of rubber-tired skidder and farm tractor on physical properties of soil in plantation areas in the north of Iran
aspen skid trail skidding machine soil disturbance timber skidding
2015/9/15
Physical properties of soil can be affected by machines that are used for skidding which have the potential to impact soil sustainability and forest productivity. The present study evaluated the effec...
The effect of coppice management on the structure, tree growth and soil nutrients in temperate Turkey
coppice soil growth dynamics forest management
2015/5/18
Coppicing was widespread throughout Europe for many centuries but was largely abandoned in the second half
of the 19th century. Currently, there has been a renewed interest in coppicing for biomass ...
Influence of vegetation on phenolic acid contents in soil
Norway spruce larch rowan willow phenolic compounds pot experiment
2015/4/24
The study described in this paper was undertaken in order to assess the impact of different woody plants on the dynamics of phenolic acids in soil. The influence of plant litter on the amount of pheno...
