Simulated Root Exudation Gradient Reveals Dosage‐Dependent Carbon Sequestration in Desertification Ecosystems

Land Degradation &Development, EarlyView.
ABSTRACT Root exudates serve as a key driver for the restoration of soil organic carbon (SOC), particularly in aeolian desertification ecosystems where aboveground litter retention is limited. While Salix cupularis is widely planted as an effective pioneer shrub for ecological rehabilitation on the Qinghai‐Tibet Plateau, how the quantity of its root ...

Rhizosphere response and resistance to fertilization

Communications Earth & Environment
Investigating the response of the rhizosphere and bulk soil to fertilization, along with the mechanisms governing their dynamic and stability, is essential to understand root and microbial functions in ecosystems.

Cereal‐Legume Rotation Benefits Soil Ecosystem Multifunctionality by Improving the Efficiency of Microbial Carbon Pump

Land Degradation &Development, EarlyView.
ABSTRACT Cereal‐legume rotation is regarded as an important agricultural management strategy for enhancing soil organic carbon (SOC) and improving soil ecosystem multifunctionality (EMF). The soil microbial carbon pump (MCP) exerts a regulatory effect on the production of microbial necromass as well as the SOC accumulation.

From Salt‐Affected Marginal Land Resource to Remediation Agent: Halophyte‐Derived Biochar for Ameliorating Cd‐Contaminated Acidic Soil

Land Degradation &Development, EarlyView.
ABSTRACT Cadmium (Cd) contamination of acidic soils poses a significant threat to ecosystem stability and crop health. This study evaluated the potential of biochar derived from the halophyte Salicornia europaea (SBC), a salt‐tolerant plant that grows on saline‐alkali marginal land, to remediate Cd‐contaminated acidic soil.

Distinct roles of bacteria and fungi in driving rhizosphere and bulk soil multifunctionality of Abies georgei in an alpine forest

BMC Plant Biology
Background Root activity creates a unique microbial hotspot in the rhizosphere, profoundly regulating soil activity and associated soil multifunctionality (SMF), the ability of soil to deliver multiple functions or services simultaneously.

Contrasting Rhizosphere Soil Stoichiometric Traits and Microbial Nitrogen Limitation Between Maize and Peanut Under Intercropping and Straw Retention

Agriculture
Extracellular enzyme stoichiometry is a key indicator for assessing nutrient limitation experienced by soil microorganisms. Yet, the characteristics of enzyme-inferred microbial nutrient limitation in rhizosphere soil under the combined agricultural ...

Carbon‐Fixing Bacterial Network Complexity Mediates Soil Multifunctionality in a Panax notoginseng‐Pinus armandii Agroforestry System

Land Degradation &Development, EarlyView.
ABSTRACT Autotrophic carbon‐fixing bacteria (CFB) are central contributors to soil carbon sequestration and biogeochemical carbon cycling in agroforestry ecosystems and can act as reliable biological indicators for evaluating agroforestry ecosystem sustainability.

Screening Maize Cultivars Enables Concurrent Safe Crop Production and Phytoremediation of Cd‐Contaminated Agricultural Soil: A Field Experiment

Land Degradation &Development, EarlyView.
ABSTRACT Conventional management of heavy metal contaminated soil faces a dual challenge. Safe utilization maintains agricultural production without removing pollutants, whereas phytoremediation cleans the soil but cannot guarantee the planted crop safety.

Bacillus subtilis Mobilizes Phosphorus by Reshaping P Pools, Sorption, and Enzyme Activities

Land Degradation &Development, EarlyView.
ABSTRACT Low phosphorus (P) availability constrains crop production in saline‐alkaline soils of Xinjiang, China. We tested whether Bacillus subtilis (B. subtilis) mobilizes soil P by altering P fractions, sorption–desorption, and P‐cycling enzymes in a saline‐alkaline cotton soil. Under conventional fertilization, B. subtilis was applied at 0 (B0), 15 (
