The figures are as follows:

Figure 1
Simulated soil domains for a (a) ridge and furrow and (b) flat soil geometry, where Ω and Φ are the total cross‐sectional areas of the two domains, ∂ΩS and ∂ΦS are the soil surface boundaries, ∂ΩB and ∂ΦB are the base boundaries, ∂ΩW, ∂ΦW, ∂ΩE and ∂ΦE are the lateral boundaries, ΩA and ΦA are the areas without root activity and ΩU and ΦU are the areas of soil containing root activity.


Figure 2
Newbury site experimental rainfall data over a 6‐month period between 1 June 2006 and 31 December 2006. The green and orange crosses indicate the time of early and late solute applications, respectively.


Figure 3
Early‐application solute profiles in the ridged and flat domains for the moderately mobile solutes (γ1, γ2, γ3) 16 and 24 weeks after solute application. A white contour line for the safety threshold of 10 μg l−1is also plotted. The ridge and furrow and flat geometries are the same as those shown in Figure 1.


Figure 4
Early‐application solute profiles in the ridged and flat domains for the highly mobile solutes (β1, β2, β3) 16 and 24 weeks after solute application. A white contour line for the safety threshold of 10 μg l−1is also plotted. The ridge and furrow and flat geometries are the same as those shown in Figure 1.


Figure 5
Early‐application solute profiles in the ridged and flat domains for the extremely mobile solutes (α1, α2, α3) 16 and 24 weeks after solute application. A white contour line for the safety threshold of 10 μg l−1is also plotted. The ridge and furrow and flat geometries are the same as those shown in Figure 1.


Figure 6
Early‐ and late‐application solute profiles in the ridged and flat domains for the slow degrading solutes (α3, β3, γ3) at the end of the 24‐week simulations. A white contour line for the safety threshold of 10 μg l−1is also plotted. The ridge and furrow and flat geometries are the same as those shown in Figure 1.


Figure 7
Total amount of solute leached beyond the plough layer in the ridge and furrow soil, Ω, and flat soil, Φ, for simulations that delayed the period of time between a solute application and a heavy rain event.
