Volume I of this report described how to evaluate the soil suitability of areas for off-road recreational motorcycle (trailbike) use on land under the jurisdiction of the Department of the Army. This soil evaluation method relied on the availability of a recent, detailed soil survey. Since such surveys are not always available, Volume II describes alternative methods of evaluating the suitability of soils for trailbike use. Volume II illustrates and describes seven alternative soil evaluation methods. Each method is defined as more or less useful in terms of its reliability and the ease and speed by which its results may be obtained. Included are descriptions of simple ways to conduct the field and laboratory soil analyses required when using alternative soil evaluation methods.
