    Soil degradation, both due to soil erosion and nutrient removal, is a major problem in cassava fields. Most of the existing management technologies that have been developed have had little success in adoption. Some of the reasons are that the technology developed is technically oriented, based on experiment station research with very little farmer involvement.

    Four environments with contrasting potential for agricultural productivity and infrastructure development were identified in Guanajuato State, Mexico, to test hypotheses about the relationship of maize biological diversity to the region's potential for agricultural productivity and infrastructure development. Samples of all types of maize grown by a random sample of farmers were collected from each environment. The maize samples were classified by race, racial mixture or type of "creolized" or improved variety.
