Description: The water management model DRAINMOD was used with 23 years of climatic data (1961-1983) to quantify the time available for fieldmachine trafficability on two Quebecsoil types (SainteRosalie clay and Saint Jude sandy-loam). The two soils, cropped to grain com, were studied in combination with four lateral subsurface drain spacings, combined withtwominimum soil air volumes, resulting in sixteen simulations. Adequate drainage was provided by a 15 m lateral drain spacing fortheclaysoilanda 30mspacing forthesandy loam.The numberof trafficabledays from April throughNovember varied widelywith soil type, drainage spacing and soil air volume. In the very wet year of 1972, a 20 m spacing for Sainte Rosalie clay resulted in an 18.2% reduction in annual trafficability, compared to 5, 10,and 15mspacings. A 35mspacingfor SaintJude sandyloam resulted in an 8.8% reduction in annual trafficabilitycompared to 15, 20, and 30 m spacings. For the purposes of trafficability and ade quate drainage, spacings of 15 m and 30 m are recommended for the Sainte Rosalie clay and Saint Jude sandy loam, respectively. For a minimum soil air volume of 30 mm,thesedrain spacings resulted in 89.9and 88.4 trafficable days per season,respectively.
