Abstract
The study was conducted to determine selected physical properties and nutrient levels of soils affected by landslides and other hazards caused by typhoon Bopha in New Bataan, Compostela Valley. Five pedons were selected from five barangays that were severely hit by the hazards. Morphological characteristics of the pedons were described in situ. Samples were taken from each soil horizon to determine the soil texture and atterber limits of the five pedons. Nutrient levels were analyzed using STK. Soils located at lower elevations and flat terrain (Pedons 2, 3 and 4) showed deeper soil profiles compared with those at higher elevations and rolling terrain (Pedon 1 and Pedon 5). Higher clay contents were obtained from Pedons 1 and 5 while sand and silt fractions were higher in Pedons 2, 3 and 4. Soils at lower elevations (Pedons 2, 3 and 4) showed lower liquid and plastic limits. All the pedons had very low NPK levels. Debris from the landslide buried the inherently fertile soil of floodplains causing a decline in the nutrient status of the soil. Application of inorganic and organic fertilizers with proper management should be done to improve the fertility of these soils. Furthermore, conservation practices should be applied at the mountainous areas to prevent the repeat of the 2012 catastrophe in Compostela Valley.
