The variants of the fertilized farmland I can see in JEI is not all possible combinations; I got:
green, red, yellow, green&yellow, red&yellow
Missing(please add):
green&red, green&red&yellow

Increases crop output(green)
Speeds up growth(red)
Prevents trampling(yellow)

Those combinations aren't possible which is why they do not show up. You can only apply either green or red fertilizer at once.
