Burrow use by Saharan striped polecat (Poecilictis libyca) in an agricultural area of central Tunisia

The Journal of Wildlife Management, EarlyView.
Saharan striped polecats in agricultural landscapes use many burrows (30–35 per season), facilitated by sandy soils. Burrow sharing is rare and mainly occurs between males and females during mating. Habitat use shifts seasonally, reflecting disturbance and soil conditions. Maintaining stable sandy habitats may be critical for persistence.

Ditch‐Buried Straw Return Improves Soil Physical Quality and Crop Biomass in Two Rice–Wheat Paddy Soil Systems

Land Degradation &Development, EarlyView.
ABSTRACT Ditch‐buried straw return (DB) is an innovative practice combining deep tillage and straw incorporation. This study aimed to evaluate its effects on soil physical quality compared to rotary tillage (RT) and identified key constraints to crop in sandy‐loam and clay‐loam paddy soils within rice–wheat systems. Two field experiments were conducted

Ecological Network Characteristics of Cultivated Land Carbon Flows in Major Grain‐Producing Regions: Case Study of Jingzhou City, China

Land Degradation &Development, EarlyView.
ABSTRACT Land‐use changes related to cultivated land significantly affect the regional carbon budget in major grain‐producing regions, yet the ecological network characteristics of cultivated land carbon flows remain insufficiently understood. This study developed an integrated framework that combined ecological network analysis with spatial analysis ...

Status of Soil Health Indicators after 18 Years of Systematic Tillage in a Long-Term Experiment

Agronomy
Long-term cultivation experiments are gaining more attention due to the possibility of following the changes in soil parameters (e.g., soil organic carbon (SOC), stock and soil health indicators, etc.).

A Study on the Distribution Characteristics of Salinity and Nutrients and the Migration Mechanism of Soil Salt in the Delingha Saline‐Alkali Soil Profile of the Qaidam Basin

Land Degradation &Development, EarlyView.
ABSTRACT Soil salinization negatively impacts the economic development and ecological environment, particularly in the arid and semiarid regions of China. The Qaidam Basin constitutes a major distribution area of saline‐alkali land in the country. However, the distribution patterns of salinity and nutrients within soil profiles and the underlying salt ...

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 ...

Combining disturbance and competition to control creeping perennial weeds in a field study on three northern European sites

Frontiers in Agronomy
Controlling creeping perennial weeds is challenging throughout all farming systems. The present study distinguished and explored three different methods to control them non-chemically: disturbance with inversion, disturbance without inversion, and ...

Seasonal Dynamics of Soil Multitrophic Biodiversity, Co‐Occurrence Network and Assembly Mechanisms Under Typical Vegetation Restoration Patterns in Karst Region

Land Degradation &Development, EarlyView.
ABSTRACT Previous studies often overlooked the dynamic effects of karst vegetation restoration on soil multi‐trophic biodiversity and the underlying community‐assembly mechanisms. To fill this gap, we performed a seasonal comparative analysis of soil biodiversity, co‐occurrence network architecture, and assembly processes across three representative ...

Ploughing-limited post-critical dynamics under chatter in turning. Harmonic balance based investigation [PDF]

, 2022
At chatter onset, as many works show, vibrations magnitudes grow until the tool exits the continuous cutting. Another magnitude limitation mechanism, namely ploughing is investigated in the present contribution, in a harmonic balance + continuation ...
