GIS-based Mapping of Crop Suitability Rating for the Re-Delineated Soil Types in Barangay Bantug, Science City of Muñoz

Abstract

The re-delineation of soil type map was conducted in agricultural land of Barangay Bantug, Science City of Muñoz, Nueva Ecija. From one soil series with two soil types in its current map using a detailed soil survey with 1:25,000 scale there are two soil series identified, these are Maligaya and Bantog Series. After the soil texture analysis of the surface soil of each random points there are six soil types found in Brgy. Bantug. The six soil types are Maligaya Clay, Maligaya Clay Loam, Maligaya Loam, Maligaya Silty Clay Loam, Maligaya Silty Clay and Bantog Clay Loam.

The six soil type maps present in Brgy. Bantug was used as land mapping units in crop suitability assessments of Wetland Rice, Upland Rice, Corn, Onion, Mango, and Sugarcane. In Maligaya Clay Loam and Bantog Clay Loam all crops are potentially highly suitable. The permanent limitations from other land mapping units are basically the rooting condition, specifically the soil surface texture. The latest taxonomic classification based on secondary data of Maligaya Series was Fine, Smectitic isohyperthermic Typic Epiaquert while Bantog series was Very fine, mixed isohyperthermic Typic Endoaquert.
