Hailun’s county profile identifies black soil as its principal soil type. A scientific demonstration zone established by the Chinese Academy of Sciences in Hailun in 2021 studies black-soil protection and crop production. Researchers describe heavy soil texture, a shallow cultivated layer and a compacted plough pan—conditions that shape how farmers and scientists manage this productive land.

Hailun’s black soil and the work of keeping it fertile
Hailun’s agricultural identity connects black-earth farming with research on soil protection and crop production.

Research beside agriculture
The Hailun demonstration area combines field trials with monitoring from ground, air and remote-sensing platforms. Its work focuses on maintaining fertile topsoil, improving cultivation systems and controlling pests with greener methods. This research connects the visible harvest to decisions made below the crop canopy. Suihua Museum’s black-soil art gallery adds a cultural view of the region’s land, while agricultural research addresses the soil as a living resource. The two forms of interpretation answer different questions, and neither replaces the other.
A landscape that needs care
The county profile provides basic geographic context, while research reports show how soil conservation has become an active project. Their dates and purposes differ: one describes the county, another reports on a defined demonstration area. Together they make a useful story about Hailun’s relationship with agriculture—an identity rooted in black earth and sustained by ongoing work to protect it. The black soil is both the basis of local agriculture and a resource that requires long-term care.
