Biomass and Volume Modeling along with Carbon Concentration Variations of Short-Rotation Poplar Plantations
biomass additivity Populus spp quantifying carbon stock short-rotation coppice stem volume equations
2024/1/22
Short-rotation forestry is of interest to provide biomass for bioenergy and act as a carbon sink to mitigate global warming. The Poplar tree (Populus × xiaohei) is a fast-growing and high-yielding tre...
Ensemble machine-learning-based framework for estimating total nitrogen concentration in water using drone-borne hyperspectral imagery of emergent plants: A case study in an arid oasis, NW China
Water resources Remote sensing Total nitrogen Hyperspectral imagery Machine learning Bootstrap
2023/12/19
In arid and semi-arid regions, water-quality problems are crucial to local social demand and human well-being. However, the conventional remote sensing-based direct detection of water quality paramete...
Impacts of Change in Atmospheric CO2 Concentration on Larix gmelinii Forest Growth in Northeast China from 1950 to 2010
treegrowth CO2fertilization tree-ring dendrochronology InTECmodel
2024/3/12
Although CO2 fertilization on plant growth has been repeatedly modeled to be the main reason for the current changes in the terrestrial carbon sink at the global scale, there have been controversial f...
Sulphate concentration and S-SO42 – flux in soil solutions in the West Carpathians Mountains on an example of submontane beech forest stand
sulphate concentrations soil water submontane beech forest West Carpathians Mts
2015/4/14
The paper presents the evaluation of data on precipitation totals and on SO42 –concentrations and S-SO42 – fluxes in lysimetric waters in a submontane beech stand. The records cover continually a 1...
Isotope ratios and concentration of N in needles, roots and soils of Norway spruce (Picea abies [L.] Karst.) stands as influenced by atmospheric deposition of N
N-deposition 15N nitrogen spruce soil
2015/2/6
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...
Characteristics of Nitrate Concentration of Headwater Streams Located in the Northwest of Tokyo Metropolitan Area
air pollutant NO3-N concentration stream water the nitrogen saturation
2009/8/28
Nitrate nitrogen (NO3-N) concentrations of stream water have been observed in the headwater catchments within Gunma Prefecture located in northwest of Metropolitan area Japan. Large differences of NO3...
Simultaneous Measurement of the Profiles of CO2 Concentration and Temperature in Deeply Developed Soils
deep soil layer penetrative soil gas/thermo profiler soil CO2 soil temperature
2009/8/24
High concentrations of CO2 in soil air affect subsurface water quality and weathering reactions; however, few simple methods have been proposed for the collection of soil air from deep soils. Therefor...
