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
Sediment and phosphorus loss in runoff from an agroforestry catchment, NW Spain
Land Degradation and Development - Tập 21 Số 2 - Trang 161-170 - 2010
M. L. Rodríguez‐Blanco, M. M. Taboada‐Castro, M.T. Taboada-Castro
AbstractThis study was conducted to evaluate the factors controlling sediment and phosphorus export in a small agroforestry catchment located in NW Spain. At the catchment outlet discharge was continuously measured and suspended sediment (SS) and total (PT), particulate phosphorus (PP) and dissolved phosphorus (DP) were determined during seven rainfall events occur...... hiện toàn bộ
Phosphorus and mowing improve native alfalfa establishment, facilitating restoration of grassland productivity and diversity
Land Degradation and Development - Tập 30 Số 6 - Trang 647-657 - 2019
Jiqiong Zhou, Gail W. T. Wilson, Adam B. Cobb, Gaowen Yang, Yingjun Zhang
AbstractSeeding legumes into degraded grasslands may effectively replace nitrogen fertilization and restore ecosystem stability by retaining or increasing native plant species diversity while increasing forage production. However, previous research indicated limited legume persistence and potential plant community diversity loss following seeding of legumes into gr...... hiện toàn bộ
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
Assessing an ecological security network for a rapid urbanization region in Eastern China
Land Degradation and Development - Tập 32 Số 8 - Trang 2642-2660 - 2021
De Zhou, Zhulu Lin, Si‐Ming Ma, Jialing Qi, Tingting Yan
AbstractRapid urbanization leads to fragmentation of landscape and destruction of the ecological security network. A sound ecological security network promotes connectivity between ecological sources and mitigates the degradation of an ecological system. However, when identifying the ecological sources of the ecological network, studies available in the current lit...... hiện toàn bộ
An insight into land use and land cover changes and their impacts in Rib watershed, north‐western highland Ethiopia
Land Degradation and Development - Tập 29 Số 10 - Trang 3317-3330 - 2018
Desalew Meseret Moges, H. Gangadhara Bhat
AbstractLand use and land cover (LULC) changes have severely threatened ecological and economic sustainability in highland Ethiopia. A clear insight into its extent and rate is, therefore, a crucial step for effective land use planning and decision making. The main objective of this study was to analyse the nature of LULC change and its impacts in north‐western hig...... hiện toàn bộ
Land degradation assessment in Southern Africa: integrating local and scientific knowledge bases
Land Degradation and Development - Tập 18 Số 1 - Trang 99-116 - 2007
Lindsay C. Stringer, Mark S. Reed
AbstractRecent attempts to address land degradation have seen calls for greater integration of scientific expertise with local knowledges. In this paper we investigate the potential for such combined understandings to enhance the accuracy, coverage and relevance of land degradation assessment. We followed a participatory approach, using methods from a variety of di...... hiện toàn bộ
Integrating local and scientific knowledge for adaptation to land degradation: Kalahari rangeland management options
Land Degradation and Development - Tập 18 Số 3 - Trang 249-268 - 2007
Mark S. Reed, Andrew J. Dougill, Michael Taylor
AbstractDespite numerous assessments of the sensitivity and resilience of drylands to degradation, there has been little research into the way affected communities innovate and adapt in response to land degradation. This paper shows how local and scientific knowledge can be combined to identify rangeland management strategies to reduce or adapt to land degradation....... 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
