Supplemental Material of the main article, including past management of the study site (with references to previous experiments) and 15-yr time series (quarter-year P losses) via surface and subsurface pathways from a clay soil in Jokioinen, SW Finland. The first 6 years were considered as a calibration period, the whole 2-ha field being under identical management (most years grass ley). During the following 9-yr period, two of the 0.5-ha plots were under no-till, whereas the other two plots were ploughed to 20 cm each autumn.
