Organic Carbon Dynamics in Different Soil Types After Conversion of Forest to Agriculture
Land Degradation and Development - Tập 26 Số 3 - Trang 272-283 - 2015
Thilde Bech Bruun, Bo Elberling, Andreas de Neergaard, Jakob Magid
AbstractState‐of‐the‐art predictive models of soil organic carbon (SOC) dynamics associated with land use changes are unable to reflect the diversity of tropical soil types as the knowledge of contrasting site‐specific factors in mediating the response of the SOC pool is sparse. This paper examines the influence of soil type and management on SOC dynamics following...... hiện toàn bộ
Effects of Tillage Methods on Soil Carbon and Wind Erosion
Land Degradation and Development - Tập 27 Số 3 - Trang 583-591 - 2016
Yong Gao, Xiaohong Dang, Yi Yu, Yubao Li, Yang Liu, Ji Wang
AbstractCurrent interest in soil‐conserving tillage in China has developed from the concern that Chinese agricultural land loses 73·8 Mg C annually. Previous research has shown that changing from conventional tillage to conservation tillage field management increases soil C sequestration. The aim of this study is to determine if no tillage with stubble retention ca...... hiện toàn bộ
Soil Conservation Through Sediment Trapping: A Review
Land Degradation and Development - Tập 26 Số 6 - Trang 544-556 - 2015
Mulatie Mekonnen, Saskia Keesstra, L. Stroosnijder, Jantiene Baartman, Jerry Maroulis
AbstractPreventing the off‐site effects of soil erosion is an essential part of good catchment management. Most efforts are in the form of on‐site soil and water conservation measures. However, sediment trapping can be an alternative (additional) measure to prevent the negative off‐site effects of soil erosion. Therefore, not all efforts should focus solely on on‐s...... hiện toàn bộ
Using woody organic matter amendments to increase water availability and jump‐start soil restoration of desertified grassland soils of Ningxia, China
Land Degradation and Development - Tập 30 Số 11 - Trang 1313-1324 - 2019
Zhigang Li, Rebecca L. Schneider, Stephen J. Morreale, Yingzhong Xie, Jian Li, Changxiao Li, Xilu Ni
AbstractSolutions are urgently needed to address the continued degradation of agricultural soils worldwide, which has severely impacted the ability to grow crops and has led to increased irrigation demand from already rapidly depleting freshwater resources. This project evaluated a unique, previously untested, type of soil organic amendment, that is, coarse wood ch...... hiện toàn bộ
Soil properties alter plant and microbial communities to modulate denitrification rates in subtropical riparian wetlands
Land Degradation and Development - Tập 31 Số 14 - Trang 1792-1802 - 2020
Lin Ma, Ziqian Xiong, Lunguang Yao, Guihua Liu, Quanfa Zhang, Wenzhi Liu
AbstractThe capacity of riparian wetlands to remove nitrogen from upland runoff through the denitrification process is mainly controlled by soil properties and biological communities. However, the pathways or mechanisms by which soil properties and biological communities may regulate riparian denitrification rates are still largely unknown. Here, we measured the po...... hiện toàn bộ
Biological Indices for Soil Quality Evaluation: Perspectives and Limitations
Land Degradation and Development - Tập 27 Số 1 - Trang 14-25 - 2016
Jorge Paz‐Ferreiro, Shenglei Fu
AbstractSoil quality is threatened by the increase in human population and by the fact that most of the cultivable land is intensively used. The initial interest in this topic focused on defining soil quality but shifted into how to measure soil quality in the late 1990s. There is a general agreement that soil biochemical, microbiological and biological properties ...... hiện toàn bộ
Identifying erosion hotspots in Lake Tana Basin from a multisite Soil and Water Assessment Tool validation: Opportunity for land managers
Land Degradation and Development - Tập 30 Số 12 - Trang 1449-1467 - 2019
Hanibal Lemma, Amaury Frankl, Ann van Griensven, Jean Poesen, Enyew Adgo, Jan Nyssen
AbstractExtensive catchment degradation throughout the Ethiopian Highlands induced by long‐term intensified land use, erosion‐prone topography, and climate causes substantial soil erosion that limits agricultural productivity and results in lake sedimentation. However, before taking soil conservation measures, management of the soil loss problem essentially needs c...... hiện toàn bộ
The effect of unconfined mine tailings on the geochemistry of soils, sediments and surface waters of the lousal area (Iberian Pyrite Belt, Southern Portugal)
Land Degradation and Development - Tập 16 Số 2 - Trang 213-228 - 2005
Eduardo Ferreira da Silva, E. Cardoso Fonseca, João Xavier Matos, Carla Patinha, Amélia Reis, Joana Oliveira
AbstractThe former Lousal mine, on the SW limb of the Lousal anticline, closed in 1988. Today Lousal is a small village, with much evidence of environmental and landscape disturbance. This is largely the legacy of mining and mine tailings dumped around the site, which, in turn, caused soil contamination and acid mine drainage. Particular attention is being given by...... hiện toàn bộ
Mulching Affects Soil Properties and Greenhouse Gas Emissions Under Long‐Term No‐Till and Plough‐Till Systems in Alfisol of Central Ohio
Land Degradation and Development - Tập 28 Số 2 - Trang 673-681 - 2017
Ahmad Nawaz, Rattan Lal, Raj K. Shrestha, Muhammad Farooq
AbstractAgricultural activities emit greenhouse gases (GHGs) and contribute to global warming. Intensive plough tillage (PT), use of agricultural chemicals and the burning of crop residues are major farm activities emitting GHGs. Intensive PT also degrades soil properties by reducing soil organic carbon (SOC) pool. In this scenario, adoption of no‐till (NT) systems...... hiện toàn bộ
Composition and diversity of prokaryotes at an iron ore post‐mining site revealed the natural resilience 10 years after mining exploitation
Land Degradation and Development - Tập 32 Số 1 - Trang 256-269 - 2021
Emanuelle Burgos Cardoso, Paulo Prates Júnior, Marliane de Cássia Soares da Silva, Alan Emanuel Silva Cerqueira, Thuany Cerqueira Jordão, Bruno Coutinho Moreira, Eduardo Gusmão Pereira, Maria Catarina Megumi Kasuya
AbstractProkaryotes play crucial roles in the rehabilitation process to restore the ecological integrity of disturbed areas. This work reports on the profiles of N‐fixing microorganisms and Actinobacteria, from DGGE, the prokaryotic composition from next‐generation sequencing (NGS) and physicochemical soil characteristics. We compared a deactivated mining site wher...... hiện toàn bộ
