We've used PostGIS to support agriculture for the last 7 years.
Our use cases are pretty straight forward

  * ST_Intersects, Union for Polygons and  MultiPolygons
  * Generation of Poly's from Area around Linestrings
  * Generation of Poly's from Area around Points turned into a Unioned Poly
  * Generation of Linestrings from a series of points
  * Dealing with snarls in points as a result of GPS drift while the
    machine sits still, fondly termed snowballs
  * Strategic use of ST_Buffer to correct for precision differences in
  * Automated alternate strategies for ST_Interesects failures that
    generally are recoverable (e.g. lines or points overlap each other
