Black Soil Properties Under Long-Term Fertilization in Northeast China

A 43.3 KB dataset from a long-term experiment in Gongzhuling, Jilin Province, China, provides physicochemical and microbial data for black soil. It includes soil organic carbon, total nitrogen, enzyme activities, and bacterial community composition from topsoil samples. The dataset, authored by runmin xia and last updated in March 2026, is intended for studying fertilization impacts on soil biogeochemistry.

Use Cases

• Modeling soil organic carbon accumulation pathways based on physicochemical parameters like SOC, TN, AP, and AK.
• Analyzing the relationship between fertilization treatments and microbial community composition based on high-throughput sequencing data.
• Investigating correlations between soil enzyme activities and nutrient availability (AP, AK) under different organic amendments.
• Comparing the effects of manure versus straw amendments on soil properties like pH, texture, and microbial biomass (MBC, MBN).

Strengths

• Data is derived from a long-term fertilization experiment, suggesting controlled conditions and temporal depth.
• Includes both physicochemical (pH, SOC, TN, AP, AK, texture) and microbial (MBC, MBN, enzymes, community) properties for a multi-faceted view.
• Samples were collected with three replicate plots per treatment, which may support statistical analysis.

Limitations

• Row count is unknown, which may limit suitability assessment for machine learning tasks.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset's 43.3 KB size indicates a very limited scope, likely containing summary or aggregated data rather than raw sequences.
