Understanding of how groundwater and surface water interact in actively managed
palm oil plantation is essential to manage water resources properly and more
effectively. Their interactions can affect the nutrient loading and the water quality.
Radon has been used to quantify groundwater discharge rate and each field sites. In
general, ammonia, nitrate and nitrite concentration in channel water ranged 0.02-0.31
NH4-N mg/L, 0.001-0.031 NO2-N mg/L and 0.001-0.063 NO3-N mg/L, respectively. For
groundwater, the concentration of nutrients ranged 0.02-1.46 NH4-N mg/L, 0.001-
0.020 NO2-N mg/L and 0.009-0.589 NO3-N mg/L, respectively. During wet season,
higher concentration of ammonia was observed in G1. A positive correlation was
observed between radon and nutrients (ammonia, nitrate and nitrite) suggested that
groundwater discharge as a source of nutrients to the channel.
