Abstract

s study aims to identify the characteristics of the soil that develops on sago land with different inundation conditions and determine the type of soil on sago land with different inundation conditions. The method used is survey method. Determination of the observation points of the soil profile at the study site was based on inundation conditions obtained through interviews with sago processing farmers at the study site. Soil characteristics on permanently flooded land are dominated by the color of glei wAhich has undergone a reduction process. On land with periodic inundation conditions that undergo an oxidation-reduction process is dominated by motling colors and in non-flooded conditions no glei or motling colors are found. In conditions of permanent inundation and periodic inundation, no identifying horizon has been found except in non-flooded conditions, a cambic (Bw) identifying horizon has been found. The dominant soil formation factors are climate (rainfall) and topography. Rainfall and topography affect the depth of groundwater and inundation. The soil formation process that occurs is the gleization process in Gleisol soils and the leaching process occurs in Kambisol soils. Differences in soil types due to differences in inundation conditions are not yet clear, but the differences in soil types are clear, namely Gleisol hydrik (Typic hydraquents), Gleisol district (Typic epiaquepts) and Gleisol fluvik (Fluvaquentic epiaquepts) and Cambisol oxic (Typic dsytrudepts).

Abstract

The purpose of this study was to categorize the soil fertility status in Teluk Elpaputih District, Central Maluku Regency. This case study uses the National soil classification system and Soil Taxonomy. The study area is placed on flat-wavy physiography (slopes 0–15 %) by the flexible observation method of the grid. In order to ensure the ground association, observation lines are 800 meters apart and checking paths are located every 400 meters. According to the National Soil Classification System, four types of soil are found: Regosol, Alluvial, Gleisol, and Cambisol. The equivalent of Soil Taxonomy has two orders Entisol and Inceptisol, four suborders Psamment, Aquent, Fluvent, Udepts, four great group Udipasmments, Hydraquents, Udifluvents, Dystrudepts, and four subgoups Aquic Udipasmments, Typic Hydraquents, Typic Udifluvents, and Oxic In addition, the soil fertility status in the study area units ranged from low to high, namely PL0G1 (high), PL0G2 (medium) land units, PL0G3 (medium), and UL1G3 (low).
