Abstract

Spodosols soil are categorized as a marginal or sub-optimum soil which has several limiting factors and potential for oil palm plantations. The main limiting factors for spodosols are the presence of a spodic layer, poor nutrients, acidic pH, low water retention capacity, and low cation exchange capacity (CEC). This study aimed to determine changes in physical and chemical soil in each layer of spodosols control and treatment hardpan breaking and mounding treatment. This study was conducted on oil palm age 13 -1 5 years on spodosols in Central Kalimantan. Each sample was taken from control block (20 ha) and treatment block (20 ha) with 5 sampling points which were composited into one. Sampling was based on depth of spodosols layers which are AP (AP0, AP+), E (E1, E2), and B (B1, B2). Observed parameter were physical (texture) and chemical soil that was to evaluate soil fertility control and treatment hardpan breaking and mounding. It used to evaluate soil fertility oil palm plantation control (T0) and treatments (T1). The results showed hardpan breaking and mounding exercise in oil palm could enhance the physical soil properties of spodosols, by improving the soil texture from sand to loamy sand (especially in layer Ap). The soil texture changing from sand to loamy sand had improved the Soil Available Water Capacity (SAWC) on spodosols from 58.3 mm to 91.7 mm. This SAWC improvement could minimize the potential of water deficit in oil palm which planted in Spodosols soil. The hardpan breaking and mounding also enhanced the chemical soil properties of spodosols, by improving pH level, C-organic, N-total, P-total, P-Bray, Exc-K, Exc-Mg, Exc-Na, and CEC.
