Evaluation of revegetation techniques for roadside construction sites

Journal of Environmental Engineering and Landscape Management, 2017
Vegetation is often used to control erosion on right-of-way construction sites, but disturbed conditions provide challenges. This research evaluated the impact of common techniques for preparing seedbeds.

High-temporal resolution fluvial sediment source fingerprinting with uncertainty: a Bayesian approach [PDF]

, 2014
This contribution addresses two developing areas of sediment fingerprinting research. Specifically, how to improve the temporal resolution of source apportionment estimates whilst minimizing analytical costs and, secondly, how to consistently quantify ...

Carbon, Nitrogen, and Corresponding Stable Isotope Signatures Reveal Channel Banks as Major Sediment Sources in a Tropical Agricultural Watershed

Land Degradation &Development, EarlyView.
ABSTRACT Uncertainties about the applicability of δ13C and δ15N as tracers of sediment sources in tropical river basins highlight the need for more in‐depth investigations of these isotopes. This study therefore assessed the effectiveness of δ13C and δ15N signatures in discriminating sediment sources in an agricultural catchment in Northeast Brazil ...

Litter quality, land-use history, and nitrogen deposition effects on topsoil conditions across European temperate deciduous forests

Forest Ecology and Management, 2019
Topsoil conditions in temperate forests are influenced by several soil-forming factors, such as canopy composition (e.g. through litter quality), land-use history, atmospheric deposition, and the parent material.

Analysis of nifH-RNA reveals phylotypes related to Geobacter and Cyanobacteria as important functional components of the N2-fixing community depending on depth and agricultural use of soil [PDF]

, 2017
In this survey, a total of 80 787 reads and 28 171 unique NifH protein sequences were retrieved from soil RNA. This dataset extends our knowledge about the structure and diversity of the functional diazotrophic communities in agricultural soils from ...

Assessment of Soil Erosion Over Six Decades in a Long‐Term Experiment Using Fallout 137Cs and RUSLE: A South American Case Study

Land Degradation &Development, EarlyView.
ABSTRACT Soil erosion remains a major global concern affecting agricultural productivity and land sustainability. This study investigates the magnitude and variability of soil erosion in a long‐term experiment (LTE) established in 1963 in Colonia, Uruguay, aiming to compare the performance of the 137Cs tracer technique and the RUSLE model across ...

The impact of juvenile tree species canopy on properties of new forest floor

Journal of Forest Science, 2013
To keep forest soils fertile, forest practitioners plant mixed stands that are composed of both economically efficient trees such as conifers and soil-improving broadleaves. This is a mandated practice in the Czech Republic.

Impact of Sugarcane Management Practices and Time Periods on Soil Organic Carbon and δ13C Signature After Paddy Rice Conversion

Land Degradation &Development, EarlyView.
ABSTRACT Land use change (LUC) from paddy rice to sugarcane cultivation strongly influences soil organic carbon (SOC) stocks, with the extent and direction of change depending on residue management and time since conversion. This study aimed to (i) evaluate SOC stock changes under different residue management practices and conversion periods following ...
