Soil Series
Properties limiting crop production
Management Recommendation
| Bantog | Poor drainage; high shrink and swell capacity upon wetting and drying producing wide cracks in the soil, hard when dry; seasonal flooding in low areas; slow permeability | Practice shallow cultivation when soil moisture is at optimum; suited for irrigated and rainfed paddy rice; maintain properly the paddy dikes | Construction of adequate drainage irrigation and flood control system due to seasonal flooding hazard in low areas; use of broadbeds, ridges or furrows and mulching; application of organic matter and farm manure | Establishment of adequate drainage and irrigation system; application of organic matter and farm manure |
| Bigaa | Surface hardening and cracking during dry season making tillage difficult; seasonal flooding in low areas; seasonal high water table; very firm consistency | Suitable for rice production due to its clayey texture; apply fertilizer to maintain the fertility of the soil; construction of adequate drainage irrigation and flood control system | Use of broad beds, ridges or furrows and mulching; timing of planting | Not suitable for rootcrops due to texture constraints |
| Buenavista | Impervious clay subsoil with concretions, low fertility; poor drainage | Suited for rice but need to apply fertilizer | Proper land cultivation; application of organic matter and animal manure to improve structure; construction of drainage | Deep plowing; application of fertilizers |
| Novaliches | Rolling topography; low OM and available P; risk of erosion; presence of coarse fragments at the subsoil | Suited for rice; construction of dikes; application of OM and fertilizer to answer fertility problem | Suited for diversified crops but need fertilizer application; construction of drainage system | Deep plowing; addition of fertilizers |
| Obando | Sandy loam texture; low WHC and excessive drainage; low fertility; subject to shallow flooding in short periods | Suitable for rice during wet season but needs ample amount of fertilizers to address the fertility problem; phosphorus application; OM application | Application of organic matter to improve soil structure; practice timing of planting; deep plowing; phosphorus application; flood control measures | Suitable for root crops due to sandy texture; Use of broad beds, ridges or furrows |
| Prensa | Dissected physiography limits paddy field size and excess elevations increase cost of extensive gravity irrigation inputs; excess 2:1 clay causes physical limitations for diversified crops; sloping topography | Establishment of adequate drainage and irrigation system; proper leveling; construction and maintenance of paddy dikes | Application of fertilizers and organic matter; requires contour cultivation; use green manure and mulches; proper timing of cultivation and planting | Establishment of adequate drainage and irrigation system; regular addition of organic matter and animal manure; proper timing of cultivation and planting |
| Quingua | Climate, seasonal flooding; low OM; excessive drainage | Suited for paddy rice; application of inorganic fertilizers to maintain the fertility of the soil; irrigation system | 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 |
| Sibul | Shallow soil due to erosion; undulating to steep topography; sometimes presence of limestone fragment at the top soil | not suited for irrigated lowland production because of irrigation constraints; leveling and terracing | Application of fertilizer and organic matter; practice contour farming; conservation tillage such as mulching and groundcover help conserve moisture, slow runoff, minimize and control erosion; mulching using organic materials help sustain soil fertility; | Contour terracing; buffer strip cropping; proper fertilization; proper timing of cultivation and planting; liming; addition of organic matter and animal manure to improve soil fertility and water holding capacity |
