Quick Summary

Shajiang tu is a type of soil found in central and western Shandong, China, specifically on the North China Plain. It is also known as "sandy ginger soil".1

This soil type appears at the lowest elevations of alluvial plains where water remains for extended periods, as well as in areas subject to annual flooding. Its name comes from the appearance of lime concretions that resemble ginger roots. Some shajiang tu soils also develop hardpan layers of limestone.1
