Abstract

The study was undertaken to assess major upland soils in Batangas Province. It aimed to determine potential of the areas to improved cropping system alternatives and generate those into a farm development models. Eight soil series were identified in the study area. The spatial distribution of soils were analysed and projected with the aid of Geographic Information Systems. Based on the analysis, majority of the soil series have moderate nutrient availability, whereas Sibul and Taal is moderately low and Tagaytay is high on nutrient availability. The result from suitability analysis by FAO framework shows that majority of the crops are moderately and marginally suitable in the area due to limitations on topography, soil physical condition and fertility. Nevertheless, development models of cropping system when applied in the area can adopt the identified improvement methods. One intensification model recommends land use shifting to pineapple cultivation due to severe limitations of Tagaytay sandy loam (8-16% slope) for corn-sweet potato production. Diversification models, on the other hand, were focused to recommend modifications of vegetables and sugarcane farming systems. Sitao is optional to vegetable productions while green pepper and animal is recommended to be integrated in sugarcane farming. Economic analysis, which is the basis of likelihood of successful adoption of farmers, confirms the profitability of the development models.
