Soil Nitrogen and Chloride Movement Profiles from Fertilizer Study

One year of data profiles the distribution of nitrogen and chloride in soil following fertilizer application. The study, conducted by SCIOPS, was published in May 1984. It tracked the movement of NH4-N and NO3-N, comparing it to chloride as a tracer.

Use Cases

• Model nitrate (NO3) movement using chloride (Cl) tracer data from soil profiles.
• Analyze the relationship between soil physical properties and the downward movement of NO3 and Cl.
• Fit soil profile distribution curves for nitrogen and chloride using a Poisson distribution model.
• Study the absorption and retention depth of ammonium nitrogen (NH4-N) in surface soil (within 10 cm).

Strengths

• Study provides a full year of temporal data on nutrient movement.
• Includes precise geographic coordinates (Latitude: 36°02' N, Longitude: 140°05' E) for the research site.

Limitations

• Dataset is temporally stale, with last update in 1984.
• Geographic scope is limited to a single coordinate point, reducing generalizability.
• Key structural details like row count, column names, and file size are unknown.
