Natural recovery of compacted soils in semiarid Montana

Auteur :
KNAPP, P. A.

Description :
Residual compaction in soils disturbed by differing land-use activities was examined in five southwestern Montana ghost towns. All towns had been abandoned for 46 to 77 years. Bulk density and macroporosity of the poorly sorted sandy loams and sandy clay loam soils were measured. A linear recovery model based on compaction measurements gathered at the townsites indicated that complete recovery times ranged from 50 to 145 years for soils compacted principally by human trampling, and from 79 to 227 years for soils compacted by vehicular traffic.
