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
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
Long‐Term Changes in Soil Carbon Stocks in the Brazilian Cerrado Under Commercial Soybean
Land Degradation and Development - Tập 27 Số 6 - Trang 1586-1594 - 2016
Eduardo Jacusiel Miranda, Janaína Braga do Carmo, Eduardo Guimarães Couto, Plínio Barbosa de Camargo
AbstractThe net effect of agriculture on soil carbon is not yet fully understood. While a number of studies on shallow profiles have been published, evidence suggests that carbon stock changes occur in deeper layers. In this study we analyzed the effect of agriculture in the Cerrado soil C looking at changes in seven different profile depths from 0 to 100 cm in a c...... 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
Sequestering carbon in soils of arid ecosystems
Land Degradation and Development - Tập 20 Số 4 - Trang 441-454 - 2009
Rattan Lal
AbstractRecent increase in atmospheric concentration of CO2 and decrease in land‐based sink capacity are attributed to numerous anthropogenic activities including increase in severity and extent of soil degradation and desertification. There is a strong link between desertification and global warming with positive feedback of mutual reinforceme...... 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
Carbon Depletion by Plowing and its Restoration by No‐Till Cropping Systems in Oxisols of Subtropical and Tropical Agro‐Ecoregions in Brazil
Land Degradation and Development - Tập 26 Số 6 - Trang 531-543 - 2015
João Carlos de Moraes Sá, Lucien Séguy, Florent Tivet, Rattan Lal, Serge Bouzinac, Paulo Rogério Borszowskei, Cléver Briedis, Josiane Bürkner dos Santos, Daiani da Cruz Hartman, Clayton Giani Bertoloni, Jadir Aparecido Rosa, Theodor Friedrich
AbstractThe continuous use of plowing for grain production has been the principal cause of soil degradation. This project was formulated on the hypothesis that the intensification of cropping systems by increasing biomass‐C input and its biodiversity under no‐till (NT) drives soil restoration of degraded agro‐ecosystem. The present study conducted at subtropical [P...... hiện toàn bộ
Carbon Sequestration in Restored Soils by Applying Organic Amendments
Land Degradation and Development - Tập 27 Số 3 - Trang 620-629 - 2016
María del Mar Montiel‐Rozas, Marco Panettieri, Paula Madejón, Engracia Madejón
AbstractThe study of different natural carbon sinks has become especially important because of climate change effects. The restoration of contaminated areas can be an ideal strategy for carbon sequestration. The studied area was affected by toxic Aznalcóllar mine spill in 1998. Restoration process of the contaminated area was based, mainly, on the use of two organi...... hiện toàn bộ
