Philippines soil condition varies accordingly due to the geospatial distribution of land causes crop constraints of nutrient uptake. One of these islands is the Samar region wherein soil is predominantly derived from sedimentary rocks. Very little information was conducted about its nutrient and fertility status in agricultural land areas. This study was conducted to evaluate the nutrient and soil fertility status of different agricultural land areas and to assess the crop suitability of soil in different municipalities of Samar. Results revealed that lowland agricultural areas of Samar possessed the greater potential for crop production relative to the upland agricultural areas as the latter has a higher amount of sand indicating the greater possibility of persistent mudstone formation. Generally, Samar has a deficient amount of phosphorous P and K as attributed by a high amount of Ca enable to displace P and K from the crops soil environment. The lowland agricultural areas are highly suitable for crop production than in upland areas. A greater amount of production inputs of P and K containing fertilizers are highly recommended in growing various types of fruit-bearing plantation crops, especially in upland agricultural areas. Adaptation of soil conservation practices is important to restore the availability of essential nutrients such as crop cover cropping, contour farming, terracing, crop rotation, mulching, green manuring, minimum tillage, and crop diversification.
