    soil nutrients completely depleted + /fertilizer -> /additional crops grown

    soil nutrients completely depleted + additional crops grown -> fertilizer

    In the explanation video, JY refers to this as a conditional statement with an additional embedded conditional statement. You can tackle each separately by first dealing with the embedded conditional statement (let's call it B: "additional crops cannot be grown unless fertilizer is applied to the soil") and then turning to the outer conditional statement (let's call it A: "if the soil's nutrients are completed depleted").

    A -> B

    soil nutrients completely depleted -> (/fertilizer -> /additional crops grown)

    The arrow turns to "and" when you "distribute" the logic from the outer conditional to the embedded conditional:

    soil nutrients completely depleted + /fertilizer -> /additional crops grown

    You can even take the contrapositive of the embedded conditional and then "distribute" the logic, like so:

    soil nutrients completely depleted -> (additional crops grown -> fertilizer)

    soil nutrients completely depleted + additional crops grown -> fertilizer

    When you're just looking at the embedded conditional, "additional crops cannot be grown unless fertilizer is applied to the soil," and you have both group 3 and group 4 conditional indicators, you can just pick one and go for it. For example, if you pick group 3 and you negate/sufficient the "unless" statement, it becomes /fertilizer -> /additional crops.

    If the soil nutrients are completed depleted then

    Additional crops can be grown arrow fertilizer applied to the soil.

    This should work well. The first situation is kinda introducing a sub world. You don't need to include all three statements in one diagram.
