Long‐Term Straw Returning Combined With Mineral Fertilization Enhances Soil Quality but Elevates P Loss Risks in a Subtropical Rice–Wheat Rotation System, Central China

Land Degradation &Development, EarlyView.
ABSTRACT Long‐term straw returning is widely promoted to improve soil quality in intensive cropping systems, yet its combined effects with mineral fertilization on soil quality and phosphorus (P) loss risks remain unclear. Using a 16‐year field experiment in a rice–wheat rotation system, we evaluated the impacts of straw returning (S), NPK ...

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.

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 (

Straw Return Combined With Nitrogen Fertilizer Application Improve Nitrogen Utilization Efficiency by Regulating Soil Physical and Chemical Properties in Spring Maize

Land Degradation &Development, EarlyView.
ABSTRACT Straw return (SR) and controlled‐release nitrogen fertilizers application can improve soil structure, enhance soil water retention, and promote crop growth. However, the mechanisms through which SR and controlled‐release nitrogen fertilizers application jointly modulate soil physical and chemical properties remain unclear.

Pedo‐Climatic Controls on Soil Health Recovery Across Cultivation Chronosequences: Hydraulic Conductivity as a Potential Link Between Soil Structure, Microbial Biomass, and Nutrient Availability

Land Degradation &Development, EarlyView.
ABSTRACT Long‐term cultivation can improve soil health, but recovery may not follow the same pathway across contrasting soil and climate conditions. A key unresolved question is whether soil health recovery is mainly associated with the release of physical–chemical constraints or with the gradual rebuilding of carbon, microbial biomass, and nutrient ...

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 ...

Estimation of MBC: MIC Ratio of Herbal Extracts against Common Endodontic Pathogens

Journal of Pharmacy and Bioallied Sciences
Herbal extracts have evoked interest owing to the small number of terpenoids and phenolic compounds, which impart antimicrobial, antioxidant, and anti-inflammatory properties. The minimum inhibitory concentration (MIC), minimum bactericidal concentration
