| 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 |
| Bolinao | Rolling topography in some areas which causes risk of erosion; shallow rooting depth; low available P | Suitable for rice but needs terracing and use of limestone outcrops for re-enforcing dikes; application of phosphate fertilizers; upland rice | Contour terracing; proper fertilization; proper timing of cultivation and planting; addition of organic matter and animal manure to improve soil fertility and application of phosphate fertilizers | Contour terracing; use of cover crops like Ipil-ipil for soil rehabilitation and source of firewood at the same time; addition of organic matter |
| Buguey | Low fertility; excessive drainage causes lack of soil moisture | Apply fertilizer to improve the fertility of the soil; OM application; construction of adequate irrigation system; construction of bunds | Apply fertilizer to improve the fertility of the soil; OM application or green manuring; construction of adequate irrigation system | Apply fertilizer to improve the fertility of the soil; OM application or green manuring |
