Soil Series
Properties limiting crop production
Management Recommendation
| Alaminos | Acid soil; low fertility; excessive erosion | Upland rice farming; liming; application of fertilizers | Contour farming and/or strip cropping; addition of organic matter and animal manure; application of phosphate fertilizers | Suitable for root crops; practice contour cropping |
| Angeles | Structureless; poor WHC; low fertility; subject to seasonal flooding; gravels present throughout the profile | Suitable for rice during wet season with supplement irrigation; fertilizer addition | Application of OM; deep plowing; practice timing of planting; irrigation system | Suitable for root crops due to sandy texture |
| Antipolo | Sloping topography that causes risk of erosion; low available P; acid soil | Suitable for upland rice; phosphate fertilizers application | Contour farming; suitable for acid-tolerant crops; liming; addition of phosphate fertilizers | Contour farming; phosphorus application; suitable for growing cassava and camote |
| Bancal | Soil cracks into clods when dry; compact | Plow and harrow with optimum moisture content to make a good tilth; irrigation system | Plow and harrow with optimum moisture content to make a good tilth; application of organic matter or animal manure to improve soil structure | Plow and harrow with optimum moisture content to make a good tilth; application of organic matter or animal manure to improve soil structure |
| Bani | Poor drainage; rolling topography causes risk of erosion; surface cracking when dry | Construction of dikes; fertilizers application; deep plowing during land preparation | Establish proper drainage and irrigation system; contour farming; addition of fertilizers; Suited for annual cash crops; application of fertilizers and liming; contour farming and/or strip cropping | Not suitable due to texture constraint |
| Bolaoen | Scattered gravels and rock fragments, and rock outcrops and boulders present; low fertility | Small areas in between hills/flat lands can be utilized for lowland rice; suitable for upland rice; application of fertilizers; use of mould board plow to manage presence of outcrops and boulders | Application of fertilizers; strip cropping; addition of organic matter and animal manure; adequate irrigation system | Production contraints due to presence of boulders and rock fragments in the subsoil |
| La Paz | High water table and local flooding in wet season preclude dry land crops, rapid permeability precludes gravity irrigation except when water table is seasonally high, low fertility | Suitable for rice during wet season but needs ample amount of fertilizers to address the fertility problem; phosphorus application | Application of organic matter; practice timing of planting; deep plowing; phosphorus application | Suitable for root crops due to sandy texture |
| Quingua | Climate, seasonal flooding; excessive drainage | Suited for paddy rice with ample irrigation supply; application of inorganic fertilizers to maintain the fertility of the soil | Suited for diversified crops; construction of adequate drainage, irrigation and flood control system; proper timing of cultivation and planting | Suited for root crops; construction of adequate drainage irrigation and flood control system; proper timing of cultivation and planting |
