Figure 5

Simulated uptake rate dynamics from 6 weeks until 14 weeks for both the low and high buffering soil. Root uptake was started at 6 weeks following dissolution of the fertiliser from day zero. Each soil has the same total quantity of P initially. The first column shows the low buffering case (buffer power 40) and the second shows the high buffering case (buffer power 519). Each row highlights one of the three root systems showing the 4 fertiliser dissolution cases: Zero fertiliser, 14-week dissolution, 1-week dissolution and 1-day dissolution within that soil type. (a) Low buffering soil with 01 root system. (b) High buffering soil with sample 01 root system. (c) Low buffering soil with sample 02 root system. (d) High buffering soil with sample 02 root system. (e) Low buffering soil with sample 03 root system. (f) High buffering soil with sample 03 root system. For visualisation purposes, root images show uptake rate at 43 days. The faded lines show the other root system measurements in each soil type to ease comparison between plants.
