You can see that at about 11% of soil water the green line flattens out (crop could not extract any more water) before we had 34mm of rain. Then there was a rapid increase followed by a few days then another 18mm of rain. Then a few days flat and now as the crop is bulking up and using a lot more water you see the "steps" (daily use) using much more water than earlier in the crops life.
The top graph is for the 700 to 800mm (70 to 80cm) zone, as you can see the crop is also drawing on this water slowly There is obviously water left in between the above zones although I did not want to make it too complicated by adding them (click to show a bigger image)
