Soil Series
Properties limiting crop production
Management Recommendation
| Alimodian | Heavy clay subsoil that can impede internal drainage and root development; topography; low fertility | Adequate fertilization; seedbed configuratio; terracing | Organic matter incorporation, liming, minimu tillage, deep plowing, mulching; suited to corn | Deep plowing; application of fertilizer |
| 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 ares; slow permeability; irrigation water | 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 systems due to seasonalfloodinghazard in low areas; use broadbeds, ridges or furrows and mulching; application of organic matter and farm manure | Establishment of adequate drainage and irrigation systems; apply organic matter and farm manure |
| Barotac | Iron and aluminum toxicity; acidic; low fertility status; difficult to manage; runoff; gravels are present in all horizon; topography | Application of phosphate fertilizers; dikes construction | Liming; application of freshly decomposed organic matter. | Not suited to rootcrops; presence of gravels that damage root development |
| Faraon | Shallow soil depth limiting productivity to shallow rooted crops; rock outcrops are present; hilly topography | Constructions of bunds | Contour farming; shallow cultivation; fertilization. | Not suited for rootcrop due to outcrops present. |
| Guimaras | Topography; low CEC; run-off | Application of fertilizers to increase yield; constructions of bunds; terracing | Organic matter incorporation; practice cover cropping, green manuring and liming; plant with legumes to low nutrient levels; terracing | Suited for camote |
| Luisiana | Highly leaches; very acidic; iron and aluminum toxicity; low base saturation and low CEC; runoff; topography | Liming; fertilizer application; best suited for rice | Practice contour farming; strip cropping and cover cropping; application of fertilizer | Best suited for root crop |
| San Rafael | Fe and Al toxicity; acidic; very low native fertility; runoff; topography | Application of fertilizers; construction of bunds | Liming; adequate fertilization; organic matter incorporation; mulching; intercropping/multiple cropping; terracing | Suited for root crops |
| Sara | Soil hardening causing surface cracking and difficulty in tillage; acidic; lack of irrigation water | Needs liming; fertilization of complete fertilizer; construction of irrigation system | Liming; timing of land preparatio; sub-soiling | Not suited to root crops |
| Sta. Rita | Soil hardening causing surface cracking and difficulty in tillage | Phosphate fertilization; best suited for rice | Organic matter incorporation; cover crops; mulching; construction of broadbeds, ridges and furrows; suited for sugarcane | Not suited for root crops due to texture constraints |
| Umingan | Presence of gravelly or stony layer at the lower subsoil. Due to this layer of stones and gravels the soil tends to be droughty; occurrence of floods during and after heavy rains | Application of fertilizer; suited for paddy rice and other crops; clearing of large gravels and rock outcrops | Construction of adequate drainage irrigation and flood control system; application of fertilizer and organic matter; suited for diversified crops; udjust the cropping season | Gravels at the lower subsoil may cause the lower yield of root crops |
