Description

The dataset provides a global map of subsoil compaction risk of arable land by farm machinery. The calculation is detailed in the publication entitled "Farm vehicles approaching weights of sauropods exceed safe mechanical limits for soil functioning" by Thomas Keller and Dani Or.

Three variables are available in this repository at 0.1° x 0.1° resolution (~10 km):

  1. the soil precompression stress at 50 cm depth (.nc)
  2. the soil stress at 50 cm depth (.shp)
  3. the subsoil compaction susceptibility index (SCSI) for arable land (.nc)
