Surface Soil Type: Silt loam to Silty clay
Family name: Fine loamy, mixed, isohyperthermic, Fluvaquentic Epiaquolls
Fine loamy textured soil with moderate amount of clay 18 35 with no particular mineral of any kind dominates in the soil mixed The soil temperature regime is isohyperthermic 22C Fluvaquentic soil which means it is subjected to periodic flooding with muddy water often enough to prevent complete incorporation of fresh sediments into the surface soil before the next flood Consequently the organic matter content decreases irregularly with depth or remains high in deep layer It Is a representative of great group Epiaquolls a Mollisol olls from the Latin mollis meaning soft Characteristically are dark colored soils which are formed under grassland This is fertile soil medium OM low P medium K with high base status and neutral to medium acid pH It has an aquic aqu moisture regime where it is saturated for long periods of time manifested by gray color with or without mottles indicating poor internal drainage Suited for intensive cultivation and for other cash crops during dry season when there is no flooding
