Evaluación de tierras con énfasis en la conservación de los recursos naturales, en la Fraylesca, México
In several ejidos of Fraylesca, Chiapas, Mexico, under a rapid erosive process; one evaluation models were developed with ALES (Automatic Land Evaluation System), using corn as primordial use class. The model evaluation shows that 71 percent of the area is not physically and economically appropriate to conventional soil use and burning; the major limitations are the possibility of mechanization, high erosion risk and nutrient availability. Without soil preparation and burning, the appropriate area is reduced to 67 percent. Without soil preparation and with burning, the result is similar, while not burning and without soil preparation there is a higher resource conservation, diminishing the inapt area (38 percent); the rest presents 34 percent with moderate aptitude and 26 percent appropriate.
