Abstract: This study investigated the temporal characteristics of precipitation chemistry, and precipitation-soil water chemistry relationship at an intensively managed farm in the UK. Data investigated were the environment change network (ECN) terrestrial observation data for the Rothamsted research farm platform at North Wyke in Devon. Results showed that temporal variability exists in the precipitation chemistry but did not show that either the soil or the precipitation was chemically impaired. Temporal variations in the precipitation chemistry were attributed to climatic effects and anthropogenic sources as informed by the trends and results of the comparison to the seawater ion ratio. Strong relationships that existed in the investigated chemical variables (except C_l− and PO₄³⁻) between the top (above 10 cm) and lower (below 10 cm) soil layers indicated significant mixing of the soil water at this profile. The study indicated significant precipitation-soil water chemistry in the clayey-rich area.
