Thinning is an important management practice for reducing plant competition and improving wood production in forests. The residues from thinning can contain large amounts of carbon (C) and nitrogen (N...
Spatial Variations in Fine Root Turnover, Biomass, and Necromass of Two Vegetation Types in a Karst Ecosystem, Southwestern China
biomass fine root turnover necromass production karst ecosystem
2023/12/6
Revealing the patterns of fine root turnover traits can aid our understanding of the mechanisms of fine roots in adapting to soil nutrient changes. In a karst ecosystem of southwest China, the fine ro...
Additive Root Biomass Equations for Betula platyphylla Suk. Plantations in Northeast China
Betula platyphylla root biomass additive equation disaggregated model
2023/12/6
Most of the forest biomass models that have been developed so far focus on the study of the aboveground biomass of forest trees and the prediction of belowground biomass remains obviously insufficient...

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...
Effects of Salt on Root Aeration, Nitrification, and Nitrogen Uptake in Mangroves
mangrove nitrogen porosity radial oxygen loss salt suberization
2024/2/26
The potential effects of salt on the growth, root anatomy, radial oxygen loss (ROL), and nitrogen (N) dynamics in mangroves were investigated using the seedlings of Avicennia marina (Forsk.) Vierh. Th...
Assessment of root-shoot ratio biomass and carbon storage of Quercus brantii Lindl. in the central Zagros forests of Iran
carbon sequestration crown diameter component Persian oak growth form
2018/3/6
Assessment of carbon storage build-up in tree stems is a difficult task due to the lack of information on their carbon
sequestration potential and allocation in different components. Similarly, high ...
