Soil Series
Properties limiting crop production
Management Recommendation
| Annam | Aluminum (Al) and Iron (Fe) Toxicity (acidic soil); run-off; sloping topography causes excessive erosion | Poorly drained soils on the alluvial basin are moderately suitable for paddy; fertilization; maintain properly the paddy dikes; suitable for upland rice during wet season | Green manuring; liming; large initial application of phosphate fertilizers; suitable for diversified crops; strip cropping | Liming; contour terracing; buffer strip cropping; addition of organic matter and animal manure to improve soil fertility and water holding capacity |
| 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 |
| Baler | Has very minimal problems; Water seepage in lowland rice production | Practice puddling the soil to minimize seepage; proper amount and timing of fertilizer application; maintenance of paddy dikes | Application of fertilizers to maintain soil fertility; green manuring or plowing under to sustain soil organic matter; crop rotation; cover cropping with legumes for tree crops; pest and diseases resistant crop species. | Application of fertilizers to maintain soil fertility; green manuring or plowing under to sustain soil organic matter; crop rotation; cover cropping with legumes for tree crops; pest and diseases resistant crop species |
| Bugko | Low fertility, droughtiness, slight salinity due to high tide flooding; poor drainage during high tide due to high standing groundwater table | Well-planned crop rotation to sustain the soil organic matter; addition of mineral fertilizers, farm manure or compost; supplemental irrigation especially during dry season | Well-planned crop rotation to sustain the soil organic matter; addition of mineral fertilizers, farm manure or compost; supplemental irrigation especially during dry season; use of broadbeds or ridges; mulching | Well-planned crop rotation to sustain the soil organic matter; addition of mineral fertilizers, farm manure or compost; supplemental irrigation especially during dry season; use of broadbeds or ridges; mulching |
| Cervantes | Soil erosion and runoff, and low fertility | Not suitable for lowland rice; for upland rice production construct terrace with proper outlets or strip cropping; fertilizer application according to needs | Observe erosion control measures, careful management and intensive conservation practices: practice close growing crops with a legume in rotation, contour tillage, strip cropping, cover cropping, grassed waterways and terracing with proper outlets; lime | Observe erosion control measures, careful management and intensive conservation practices: practice close growing crops with a legume in rotation, contour tillage, strip cropping, cover cropping, grassed waterways and terracing with proper outlets; lime |
| Guimbalaon | Poor nutrient retention (leaching of bases); acidic; P and K deficiency (due to fixation); presence of hardpan; low moisture; severe erosion; presence of rock outcrops that impede drainage | OM incorporation; liming; suitable for rice but needs terracing and use of outcrops for re-enforcing dikes | Contour terracing/farming; erosion prevention and water control practices; proper fertilization; OM incorporation; liming; subsoiling to break hardpan | Liming; proper fertilization and OM incorporation; contour terracing; subsoiling to break hardpan |
| Polillo | low fertility, droughtiness, slight salinity due to high tide flooding | Well-planned crop rotation to sustain the soil organic matter; addition of mineral fertilizers and organic matter to improve fertility, structure and texture; use of farm manure or compost; supplemental irrigation especially during dry season; mulching. | Well-planned crop rotation to sustain the soil organic matter; addition of mineral fertilizers and organic matter to improve fertility, structure and texture; use of farm manure or compost; supplemental irrigation especially during dry season; mulching | Well-planned crop rotation to sustain the soil organic matter; addition of mineral fertilizers and organic matter to improve fertility, structure and texture; use of farm manure or compost; supplemental irrigation especially during dry season; mulching |
| 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 |
| Tagkawayan | Soil Erosion and runoff, and low fertility; presence of | Not suitable for lowland rice; for upland rice production construct terrace with proper outlets or strip cropping; fertilizer application according to needs. | Observe erosion control measures, careful management and intensive conservation practices: practice close-growing crops with a legume in rotation, contour tillage, strip cropping, cover cropping, grassed waterways and terracing with proper outlets; lime a | Observe erosion control measures, careful management and intensive conservation practices: practice close-growing crops with a legume in rotation, contour tillage, strip cropping, cover cropping, grassed waterways and terracing with proper outlets; lime a |
| Umingan | River flooding; gravelly subsoil layer causes drought | Application of fertilizer; clearing of large gravels and rock | Construction of adequate irrigation and flood control system; application of fertilizer and organic matter; suited for diversified crops | Fravelly subsoil may cause lower yield of root crops |
| Zaragosa | Becomes under water during rainy season due to low physiography; very poor drainage; forms into clod which causes difficulty in tillage and surface cracking when dry. | Suitable for paddy rice; minimize drying of soil during dry season | Construction of adequate irrigation and flood control system; OM application or green manuring | Not suited due to soil hardening and cracking that may impede plant root or tuber |
