Soil Series
Properties limiting crop production
Management Recommendation
| Alimodian | Heavy clay subsoil that can impede internal drainage and root development; hilly topography; acidic | Adequate fertilization; seedbed configuration; terracing; liming in upland rice | Organic matter incorporation; liming; minimum tillage; deep plowing; mulching | Deep plowing; adequate fertilizer application; intensive soil conservation practices |
| Bantog | Poor drainage which can cause low N mineralization and Zn deficiency; very hard when dry, and difficult to cultivate when wet; seasonal flooding in low areas; slow permeability | Practice shallow cultivation when soil moisture is at optimum; adequate water control systems; proper maintenance of dikes | Adequate drainage, irrigation, and flood control systems; use broadbeds, ridges or furrows and mulching; application of plant residues and animal manure | Provide adequate drainage and irrigation systems; apply organic residues and farm manures |
| Bauang | Hilly topography; low fertility; excessive run-off; slightly acidic | Terracing and adequate fertilization | Application of farm manure and plowing under of legumes to supply organic matter; terracing; contour tillage; crop rotation. | Not suited to root crops due to shallow soil depth. |
| Makato | Difficult to cultivate when wet, hard when dry | Adequate fertilization; adequate irrigation and provision of drainage systems | Application of farm manure and plowing under of legumes | Establish adequate drainage and irrigation systems; adequate fertilization; proper timing of cultivation and planting |
| San Manuel | Annual flooding for short periods and excessive drought during dry months | Suited for paddy rice during wet season and with adequate irrigation during dry season; respond well to N fertilization | Adequate flood control systems, use broadbeds and ridges | Adequate drainage, irrigation, and flood-control systems, regular addition of organic matter |
| Sapian (upland) | Presence of rock outcrops; shallow depth; hilly topography; excessive drainage; low fertility | Adequate fertilization; liming upland rice; terracing; adequate irrigation | Adequate fertilization with liming; organic matter incorporation; mulching; intercropping/ multiple cropping; contour farming | Adequate fertilization with liming; organic matter incorporation; contour farming |
| Sara | Soil becomes hard upon drying creating wide cracks at the surface; difficult to till; acidic; lack of irrigation water; Fe toxicity | LIming in upland rice; application of organic manures to improve soil tilth; adequate fertilization; irrigation systems with adequate drainage; alternate wetting and drying; responds well to N & P fertilization | Liming; land preparation with adequate moisture; subsoiling | Not suited to root crops due to heavy texture of the soil |
| Sigcay | Strong relief; acidic; high in iron | Recommended for upland rice only; adequate fertilization with liming and organic matter incorporation | Liming and adequate fertilization; organic matter incorporation; contour farming | Adequate fertilization and contour farming |
| Sta. Rita | Soil becomes hard upon drying causing surface cracking and difficulty in tillage; K and ammonium (NH4+) fixation; poor drainage causing Zn deficiency and slow mineralization of N | Best suited for lowland rice; adequate and balance fertilization; phosphates fertilization; adequate drainage system; Zn fertilization when deficient | Organic matter incorporation; cover crops; mulching; construction of broadbeds, ridges, and furrows | Not suited for root crops due to heavy texture of the soil. |
| Umingan | Relatively low fertility; presence of gravels and stones in the subsoil; excessive downward movement of water, hence tend to be droughty; seasonal flooding especially after heavy rains | Adequate fertilization; organic matter incorporation to improve soil fertility and water holding capacity | Adequate drainage, irrigation and flood control systems; adequate fertilization; organic matter application; adjust cropping seasons to prevent hazards of flooding especially during rainy seasons | Gravels and stones impedes root development, hence may cause lower root yields |
