What fertilizer is high in iron?

IRON FERTILIZERS
Ferrous sulfate (FeSO4) contains about 20% iron. This fertilizer is inexpensive and is mainly used for foliar spraying. Applied to soil, it is often ineffective, especially in pH above 7.0, because its iron quickly transforms to Fe3+ and precipitates as one of the iron oxides.

Will Ironite lower soil pH?

Ironite is marketed as a soil amendment for alkaline soils. Phosphorus, a key plant nutrient, is also "fixed" in alkaline soils in a form that plants cannot use. Ironite is thus used to adjust the soil's pH to make it less alkaline and to allow the plant to more easily absorb iron and phosphorus.
