RESUMEN

Lysimeter experiments were conducted to study the leaching of [14C]dichlorprop and [3H]water through different soil columns. Results from soil columns collected at Haslemoen showed that an upper silt loam layer (0-18 cm) had higher retention capacity than the underlying sandy loam (35-60 cm) and fine sand (70-95 cm) layers. Leaching through silt clay loam (0-18 cm) columns from Ullensaker was very fast. When the columns received an amount of water corresponding to approximately 10 mm precipitation, up to 50% of the added [14C]dichlorprop leached through the columns. This is probably due to rapid downward movements through macropores (e.g. cracks).
