Characterizing Soil Penetration Resistance of Planted Sago Palm (Metroxylon spp.) Under Mineral Soils Ecosystem

In-situ soil assessment such as field compaction can often be a helpful approach in help determining suitability for certain crops. In this study, an was conducted to characterize the Soil Penetration Resistance (SPR) planted sago palm (Metroxylon spp.) plantation at different growth of rosette and trunking stages under mineral soils ecosystem. SPR in-situ would provide beneficial guideline site indicator land before establishing plantations, especially on soils. The study Mukah, Sarawak, with two sites Oya Talau. stage Talau were stage, respectively. types both consisted Gley (clayey) significant development subsoil horizon. measurements taken using Hasegawa-type cone penetrometer. SSSED more compact than river research station from shallow depth subsurface ranged between 7.5 46.8 J cm-1, while 1.9 cm-1 11.1 cm-1. Although there difference 0-20 cm 80-100 depths, are considered suitable areas plantations. Using practical convenient assessing cultivation, identify potential establishment cultivation area fundamental tools landowners preparing their future cultivation.
