Distribution of soil morphology and physicochemical properties to assess the evaluation of soil fertility status using soil fertility capability classification in North Galela, Indonesia

One of the indicators land productivity assessment is soil fertility. The causes infertile have been widely reported. This study aimed to evaluate fertility using Soil Fertility Capability Classification (SFCC) approach and determine relationship between morphological physiochemical properties research was conducted in North Galela Sub-district, Halmahera Regency. framework began with interpretation thematic maps, surveys, field observations, making evaluation maps. sampling carried out based on stratified random method supported by laboratory measurements according USDA international standards. result showed that area had 14 statuses. classes having most significant limiting factor were loamy texture (Ø<0.002 mm), rock surface, gravel subsoil, moderate salinity (0.2-0.4 mS cm<sup>-1</sup>), low exchangeable K (<20 cmol<sub>(+)</sub> kg<sup>-1</sup>), sloping slope (8%) Lithic Haprendolls type subsoil >15% outcrop, (0.2-0,4 Na saturation >15%, a rather steep (14%) Eutrudepts type. Both these top layer texture, bottom contains clay <35%, factors hard inhibiting root depth 50 cm, extremely nutrient reserve, electrical conductivity (EC) high Na. found Sub-district root-restricting layer, K, conductivity, saturation, slope, gravel.
