Conversion of climax Dipterocarp forest for agricultural purposes has resulted in a decline in productivity of light textured soils in Northeast Thailand. To quantify the degree of chemical degradation that these soils have undergone, a survey was undertaken of six paired sites where adjacent Dipterocarp forest soils were compared to continuously cropped systems that had been under production from 37-100 years. Surface charge fingerprints along with soil chemical and physical attributes were determined on selective depth intervals.
