Fig. 3: Weekly rainfall amount (open-field rainfall volume for agricultural fields, throughfall volumes for the forest stages) versus weekly phosphorus (P) deposition, in agricultural field (Ag), 5- (5 yrs), 12- (12 yrs), 20- (20 yrs), and 60-year-old forest (60 yrs).

Solid lines show significant log–log fits via standardized major axis regression, while dashed lines indicate insignificant regressions (P-value > 0.1). Boxplots show the median, the 25th and 75th percentile and the 1.5 interquartile range spread for the weekly P deposition loads. Points in represent the individual weekly measurements of composite samples (n = 8) per plot for rainfall volume and P deposition.
