Variations in Soil Properties and CO2 Emissions of a Temperate Forest Gully Soil along a Topographical Gradient
CO2 emission respiration C sequestration forest gully forest soil enzymatic activity
2024/1/11
Although forest soils play an important role in the carbon cycle, the influence of topography has received little attention. Since the topographical gradient may affect CO2 emissions and C sequestrati...
Influence of Soil Properties on P Pools and Its Effect on Forest Productivity in Mediterranean Calcareous Soils
calcareous soils Mediterranean ecosystem phosphorus availability phosphorus fractionation semiarid environment sequential extraction
2023/12/11
Although soil phosphorus is essential for vegetation growth it is not always found in labile forms, hampering its absorption by plants, and is limited in forest ecosystems. This study explores soil P ...
The Functional Structure of Tropical Plant Communities and Soil Properties Enhance Ecosystem Functioning and?Multifunctionality?in Different Ecosystems in Ghana
functional traits functional diversity multifunctionality plant spost-mining restorations resource use strategies tropical forest West Africa
2023/11/20
Plant functional traits are useful in tracking changes in the environment, and play an important role in determining ecosystem functioning. The relationship between plant functional traits and ecosyst...
Assessing the amount of soil organic matter and soil properties in high mountain forests in Central Anatolia and the effects of climate and altitude
forest soil topographic conditions climate model semi-arid regions Turkey
2017/6/26
The objectives of this study were to determine the amounts of soil organic matter (SOM) stored within surface soils of high mountain forests and how the SOM amounts are affected by aridity and altitud...
