Figure 2

Change of soil solution pH with time in the fertiliser layer in experiments 2 (open symbols) and 3 (filled symbols) for treatments control (“C”, circles), urea (“U”, triangles) and urea with nitrification inhibitor (“U+NI”, squares). First sampling point (-1 DAP) defines starting conditions for root growth in experiment 3. Asterisk indicates significant difference between planted and unplanted treatments at p < 0.01 (**), ns = not significant. Error bars indicate standard error.
