#cagayan soils

This study is focused on determining soil morphological, physical and chemical properties of major rice areas in Cagayan province, Philippines that aimed to serve as a reference for identifying crop production constraints and defining appropriate management options for rice and other crops in the province. Representative pedons were investigated from the major rice municipalities in the province. Morphological properties of soils were investigated in situ. Soil samples were taken and analyzed for their chemical and physical properties. Ten soil series were tested and identified as Alaminos (Typic Kanhaplustult), Bantay (Typic Eutrustept), Buguey (Typic Ustipsamment), Carig (Typic Eutrustept), Isabela (Vertic Tropaquept), Quingua (Typic Epiaqualf), San Fernando (Ustic Endoaquert), San Manuel (Fluventic Eutrudept), Sta. Rita (Typic Epiaqualf), and Toran (Vertic Tropaquent).

This study was conducted to develop soil constraints and management options for rice areas in Cagayan province, Philippines. Soil samples were taken from sixteen rice production municipalities in the province. Morphological properties of soils were investigated in situ. Samples were analyzed for their chemical and physical properties. Thirteen soil types were identified as Sta Rita clay loam, Toran silt clay, Isabela clay, Bantay clay loam, Buguey loamy sand, Quingua clay loam, San Manuel silt loam, Carig clay loam, Buguey sand, Alaminos silt clay, San Fernando clay, Toran loam, Quingua silt loam. Crop suitability analysis of these soils was done based on the soil characteristics studied per series and known requirements of each crop. Production constraints were identified and management practices recommendations were provided based on the recognized problems per soils series.
