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
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 offers a pragmatic option to
imp...
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
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 where mining ended about
10 years ago...
Sediment and phosphorus loss in runoff from an agroforestry catchment, NW Spain
Land Degradation and Development - Tập 21 Số 2 - Trang 161-170 - 2010
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 occurred in autumn. Sediment and
sedim...
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
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 commercial grain
farm. We also use...
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
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 grasslands,
constraining successful...
Sequestering carbon in soils of arid ecosystems
Land Degradation and Development - Tập 20 Số 4 - Trang 441-454 - 2009
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 reinforcement. The biophysical process
is also driven by social, ...
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
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 the conversion of forests to
ann...
Effects of Tillage Methods on Soil Carbon and Wind Erosion
Land Degradation and Development - Tập 27 Số 3 - Trang 583-591 - 2016
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 can reduce soil carbon loss
and ero...
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
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 [Ponta
Grossa (PG) site] and tropic...
Carbon Sequestration in Restored Soils by Applying Organic Amendments
Land Degradation and Development - Tập 27 Số 3 - Trang 620-629 - 2016
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 organic amendments:
leonardite (LE) and...
