2025-11-17 ChinaXiv: chinaxiv-202511.00153 Original EN

Spatiotemporal forecasting of surface soil moisture (SSM) is recognized as a critical scientific issue in precision agricultural irrigation, regional drought monitoring, and early warning systems for extreme precipitation. However, long-term forecasting continues to pose formidable challenges becaus…

Assessment of organic carbon stock and labile carbon in soils of the Gataaya Oasis, Tunisia (Postprint)

Oasis soils in Tunisia are characterized by low soil organic carbon (SOC) stocks, primarily due to their coarse texture and intensive irrigation practices. In the Gataaya Oasis, soils receive 3.000 to 4.000 L/m2 annually through submersion irrigation, leading to a rapid decline in SOC stocks. Despit…

Spatial variability characteristics and drivers of surface soil nitrogen fractions in the drylands of northern China (Postprint)

ZHANG Shihang, CHEN Yusen, ZHOU Xiaobing, ZHANG Yuanming, ZHOU Xiaobing
2025-11-17 ChinaXiv: chinaxiv-202511.00157 Original EN

In dryland ecosystems, nitrogen (N) is the primary limiting factor after water availability, constraining both plant productivity and organic matter decomposition while also regulating ecosystem function and service provision. However, the distributions of different soil N fraction stocks in dryland…

Health risk assessment of heavy metals in coal mine soils of Northwest China (Postprint)

Li Yun, ZHUANG Zhong, XIA Qianrou, Shi Qingdong, ZHU Jiawei, WANG Peijuan, LI Dinghao, Yryszhan ZHAKYPBEK, Serik TURSBEKOV, XIA Qianrou

Coal mining renders soil susceptible to heavy metal (HM) accumulation, adversely affecting the ecological environment and human health, particularly in extremely arid and vulnerable regions. This study collected soil samples from the Heishan open-pit coal mine in Turpan City, Northwest China, to ass…

Effect of long-term restoration on soil phosphorus transformation and desorption in the semi-arid degraded land, India postprint

Jyotirmay ROY, Dipak Ranjan BISWAS, Biraj Bandhu BASAK, Ranjan BHATTACHARYYA, Shrila DAS, Sunanda BISWAS, Renu SINGH, Avijit GHOSH, Avijit GHOSH
2025-07-07 ChinaXiv: chinaxiv-202507.00070 Mixed Source

Understanding how different vegetation-based restoration practices alter soil chemical and microbial characteristics is crucial, as restoration practices influence phosphorus (P) transformation and fractions and modify P adsorption behavior during the restoration process of degraded land. This study…

Artificial cyanobacteria crusts can improve soil fertility and plant growth in a semi-arid area, northern China (Post-print)

JING Haimeng, ZHOU Nan, Yu Tantai, ZHAO Yunge, ZHAO Yunge
2025-07-07 ChinaXiv: chinaxiv-202507.00072 Mixed Source

Artificial cyanobacteria crusts are formed by inoculating soil with cyanobacteria. These crusts help prevent soil erosion and restore soil functionality in degraded croplands. However, how fast the artificial cyanobacteria crusts can be formed is a key issue before their practical application. In ad…

Effects of mixed-based biochar on water infiltration and evaporation in aeolian sand soil (Postprint)

ZOU Yiping, ZHANG Shuyue, Shi Ziyue, ZHOU Huixin, ZHENG Haowei, HU Jiahui, MEI Jing, BAI Lu, JIA Jianli
2022-05-09 ChinaXiv: chinaxiv-202205.00022

Abstract: Aeolian sandy soil in mining areas is characterized by intense evaporation and poor water retention capacity. This study was designed to identify a suitable biochar application method to improve soil water infiltration and minimize soil water evaporation for aeolian sandy soil. Using an in…
