Simulated total phosphorus uptakes integrated over the whole experiment for different P dissolution rates averaged across 3 root systems (a,b) and total uptakes per root surface area (c,d) over the fertiliser treatments. Error bars show standard deviation, n = 3. (a) Total uptake averages in the low buffering soil. (b) Total uptake averages in the high buffering soil. (c) Total uptake per root surface area averages in the low buffering soil. (d) Total uptake per root surface area averages in the high buffering soil. For visualisation purposes, root images show uptake rate at 43 days.
