The study was conducted to determine the relationship between hydrological (infiltration, hydraulic activity and water holding capacity) soil qualities and land suitability of four major landscape: coastal, alluvial, foothills, mountain for selected crops in Pangasinan province [Philippines]. Results showed that the hydrologic soil qualities vary with different physiographic mapping units (PMU). Mapping units with coarse textured soils have slow to moderate infiltration rate but have higher water holding capacities. Infiltration rate and hydraulic conductivity tend to be more rapid under wooded/grassland than under rice/vegetable areas. Infiltration rate and hydraulic conductivity are significantly correlated to land suitability for rice and coconut but not for corn, beans, mungo, peanut, vegetables, sugarcane and tobacco. In terms of water holding capacity and land suitability, rice and corn are positively correlated but not for bean, mungo, peanut and coconut.
