Accretionary pedogenesis and Holocene climate evolution in black soil region of northeast China: Evidence from a sedimentary profile

The black soil region of the Songnen Plain, one of the world’s three major black soil belts, is critical for China’s grain security, yet the formation mechanism of its thick, organic-rich soils remains insufficiently quantified. Here, we investigate the ZYHPM01 profile in the eas...

Study on the Differentiation of Microbial Communities Under Different Soil Types in the Typical Black Soil Area of Songnen Plain

Soil type imposes multilayered environmental filtering via physical structure, chemical properties, and resource availability, shaping microbial community assembly. Using 70 samples (black soil n = 27, meadow soil n = 32, and brown soil n = 11) from a typical black soil region of...

Source identification and risk assessment of potentially toxic elements in surface soil of townships in the northwest Hebei region

Abstract Soil environmental quality in townships is related to the development of rural revitalization and the smooth flow of urban-rural integration and development. However, the quality of soil environment in townships may be exposed to potential risks of potentially toxic elem...
