This study investigates the dynamics of nutrient cycling within closed-system peatland ecosystems, focusing on the role of nutrient leaching in enhancing biomass productivity. Conducted in a coconut plantation in Pulau Burung District, Indragiri Hilir Regency, Riau Province, the research quantitatively assesses the leaching of essential nutrients into a 10 cm layer of peat soil resulting from cover crop decomposition. These cover crops, integral to the plantation’s organic coconut production strategy, are managed through periodic cutting (every four months) and natural decomposition on the field.
