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 ...
Patterns and Internal Stability of Carbon, Nitrogen, and Phosphorus in Soils and Soil Microbial Biomass in Terrestrial Ecosystems in China: A Data Synthesis
spatial pattern C:N:P vegetation types nutrient limitation homeostasis
2023/12/11
Inspired by the strict constraint ratio (relatively low variability) between carbon (C), nitrogen (N), and phosphorus (P) in global soils and soil microbial biomass, our study explores the biogeograph...
Soil Organic Carbon Pools and Associated Soil Chemical Properties under Two Pine Species (Pinus sylvestris L. and Pinus nigra Arn.) Introduced on Reclaimed Sandy Soils
afforestation mine sites alien species SOM DOC extractable carbon nitrogen
2023/12/6
The roles of different tree species and their impacts are key in assessing the dynamics of soil restoration in afforested post-mining sites. The objective of this study was to compare the effect of Sc...
Ecosystem Carbon Stocks and Their Annual Sequestration Rate in Mature Forest Stands on the Mineral Soils of Estonia
forest ecosystem phytocoenosis soil cover organic carbon stock phytomass annual increase
2023/12/4
Mature forest ecosystems are the most considerable reservoir of organic carbon (OC) among terrestrial ecosystems. The effect of soil type on aboveground OC stocks and their annual increases (AI) of ov...
Phytoremediation potential evaluation of multiple Salix clones for heavy metals (Cd, Zn and Pb) in flooded soils
Phytoremediation multiple Salix heavy metals
2023/6/2
Climate-induced flooding makes soil more vulnerable to heavy metal contamination, posing challenges for soil remediation. Salix has the potential to cope with flooding stress and environmental contami...
Effects of CaO on the Clonal Growth and Root Adaptability of Cypress in Acidic Soils
CaO Clonal Growth Root Adaptability Acidic Soils
2023/6/2
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...
Carbon Feedback from Forest Soils will Accelerate Global Warming,26-Year Study Projects
Carbon Feedback Forest Soils Accelerate Global Warming 26-Year Study Projects
2017/10/25
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...
Neutralizing acidic forest soils boosts tree growth,causes spike in nitrogen export
Neutralizing acidic soils tree growth causes spike nitrogen export
2016/7/4
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...
Sustainable forestry and iron compounds in karstic soils: qualitative and semi-quantitative results focused on the occurrence of Fe-compounds on mineral particles
