Variation in Soil Organic Carbon and Total Nitrogen Stocks Across Elevation Gradients and Soil Depths in the Mount Kenya East Forest

Land
Understanding how elevation gradients and soil depths influence soil organic carbon stocks (SOCS) and total nitrogen stocks (TNS) is essential for sustainable forest management (SFM) and climate change mitigation.

Soil health and microbial network analysis in a wheat-maize cropping system under different wheat yields [PDF]

Frontiers of Agricultural Science and Engineering
Healthy soil is crucial for sustainable agriculture with soil microbiomes being key to soil health. However, comprehensive assessments of soil health and microbial community structures under different wheat yields have not been made.

Plant Trait‐ and Soil‐Mediated Responses of Herbaceous Aboveground Biomass Across Community Types Along a Degradation Gradient in the Desert Steppe

Land Degradation &Development, EarlyView.
ABSTRACT Grassland degradation profoundly alters the structure and function of desert steppe ecosystems. However, the responses of herbaceous aboveground biomass (Herb‐AGB) to degradation across different plant community types and the underlying mechanisms remain poorly understood.

Effects of Fertilization and Wheat Straw Management on Rice Yield and Greenhouse Gas Emissions in Paddy Fields

Land Degradation &Development, EarlyView.
ABSTRACT Environmental pollution caused by excessive nitrogen fertilization has become increasingly serious, making optimized fertilization and straw management critical for improving agricultural sustainability. This study involved a two‐year field trial with three fertilization strategies: conventional fertilization (CF), 23.50% nitrogen reduction ...

Contrasting Biogeographic Patterns of Bacterial and Archaeal Diversity in the Top- and Subsoils of Temperate Grasslands

mSystems, 2019
Biogeographic patterns and drivers of soil microbial diversity have been extensively studied in the past few decades. However, most research has focused on the topsoil, while the subsoil is assumed to have microbial diversity patterns similar to those of

Coupling of Physical Protection and Molecular Composition Drives Carbon Sequestration Divergence in Soils Planted With Different Tea Varieties

Land Degradation &Development, EarlyView.
ABSTRACT Tea plantations represent significant carbon (C) sinks in agricultural landscapes, yet how variety‐specific organic inputs are associated with the molecular composition and stability of soil organic carbon (SOC) within aggregate hierarchies remains unclear.

Effects of Straw Incorporation and Tillage Depth on Soil Quality in Mollisol Profiles

Land Degradation &Development, EarlyView.
ABSTRACT Although improvements in soil quality under straw incorporation have been well documented, responses across soil profiles under different tillage depths remain unclear. To address this issue, a field experiment was established in 2011 in Mollisols with conventional tillage (20 cm depth) without straw (CT) and with straw (SCT), no tillage with ...

Evaluating the restoration potential of transferred topsoil

, 2013
Global change, population growth and urbanisation are ever-increasing pressures on biodiversity and ecosystem function. Given that conservation of existing natural fragments will not be sufficient to maintain extant biodiversity or meet conservation ...
