Looking at the bed, why not raise the level with potting mix, or dig potting mix or a little manure, not too much manure, into the soil that is there and raise the level? It already looks as if most of the sides are in place to raise the bed.
Sorry but switching to iron sulphate doesn't make any sense when you've already got iron chelate. Manure won't necessarily lower your soil pH, but adding iron chelate adds usable iron to the mixture if it still needs it. If the pH is high then iron sulphate can get "tied up" just the same as the iron already in the soil is. Yes manure can improve the soil, but switching the type of iron for something less useful I just don't get.
