As a general conclusion of this study, both chemical and physical limitations are affecting crop yields and tree production.  Special attention needs to be given to the introduction of crop or tree species that are tolerant of high pH.  Crop production should be focused on the better land that has the greatest potential.  Practices aimed at sustaining the relatively high percentages of organic matter in all soils should be given special emphasis in order to minimze nutrient imbalance and moisture retention.
