Abstract

This study aims to determine the soil mineralogy and soil chemical properties at two rainfed soil pedons in Sidomukti, Gorontalo. This study was conducted at 2 pedon of rainfed paddy soils from Sidomukti Village Mootilango District of Gorontalo Regency. Implementation of the field based on the location of the example profile (pedon). The soil profile is made and sampled in accordance with the principles of soil surveying. Result of this research showed that Pedon PNS1 had easily weathered minerals (albite, sanidin and green hornblende) more than pedon PNS2. While the clay mineral content of pedon PNS1 dominated by smectite and kaolinite. Both pedon generally pH slightly acid to slightly alkaline and negatively charged clean, C-organic content is very low, bases-dd predominantly calcium (Ca-dd) with the sequence: Ca> Mg> K> Na, cation exchange capacity and base saturation dominant high and very high. However, the pedon PNS1 was better than pedon PNS2 of soil fertility.
