The results of the land suitability evaluation show that the actual land suitability class for food crops (rice, corn, soybeans) are classified as S3 (marginally suitable) to N (not suitable) with limiting factors such as rainfall, P- available, slope, erosion hazard and texture. For land suitability classes, potential food crops (rice, corn, soybeans) are classified as S1 (very suitable) to N (not suitable) with the limiting factors being slope and texture. Efforts to improve that can be done in overcoming the limiting factors include irrigation, applying fertilizers, and making terraces.
