Their amount and movement within soil solution can determine its fertility to accomodate plant growth. The dissolved nutrients are moving together in the form of cations and anions. This study aims to determine the amount of dissolved cation-anion in the soil solution and to evaluate its relationship. Field trial was conducted at tropical rainforest of Bukit Duabelas National Park. The Lisymeter was installed on each Typic Hapludult soil horizon to accommodate percolated water. The leached water sample was extracted and each cation (NH<sub>4</sub><sup>+</sup>, Ca<sup>2+</sup>, Mg<sup>2+</sup>, K<sup>+</sup>) and anion (PO<sub>4</sub><sup>3-</sup>, Cl<sup>-</sup>, SO<sub>4</sub><sup>2-</sup>, NO<sub>3</sub><sup>-</sup>) concentration were measured. Data were analyzed using independent-t stastical test, Spearman correlation, and stepwise linear regression. The results show that the total amount of cation and anion are significantly higher in the AO horizon than the AB and B horizons. The correlation analysis results show that each cation has a strong correlation to each anion (correlation value > 0.80) except PO<sub>4</sub><sup>3-</sup> ( ~ 0.70). Stepwise linear regression model shows that NH<sub>4</sub><sup>+</sup> has the strongest relation to NO<sub>3</sub><sup>-</sup>, PO<sub>4</sub><sup>3-</sup>, and Cl<sup>-</sup> with R<sup>2</sup> adj.= 0.75, Ca<sup>2+</sup> to NO<sub>3</sub><sup>-, </sup>PO<sub>4</sub><sup>3-</sup>, and SO<sub>4</sub><sup>2-</sup> (R<sup>2</sup> adj.= 0.856), Mg<sup>2+ </sup>to NO<sub>3</sub><sup>- </sup>and PO<sub>4</sub><sup>3-</sup> (R<sup>2</sup> adj.= 0.815), and K<sup>+</sup> to PO<sub>4</sub><sup>3-</sup> and Cl<sup>-</sup> (R<sup>2</sup> adj.= 0.845). It can be concluded that NO<sub>3</sub><sup>-</sup>, Cl<sup>-</sup>, SO<sub>4</sub><sup>2-</sup>, and PO<sub>4</sub><sup>3-</sup> are directly involved as cation co-pairing agents in the soil nutrient movement and leaching process.</em>}, number={4}, journal={Jurnal Pengelolaan Sumberdaya Alam dan Lingkungan (Journal of Natural Resources and Environmental Management)}, author={PutraGilang Sukma and Hartono, Arief and Anwar, Syaiful and Murtilaksono, Kukuh}, year={2019}, month={Dec.}, pages={960-969} }
