It's a good additive

In western Colorado we have to use a lot of mulch to change soil texture. In consequence, sometimes the nitrogen and iron gets locked in the soil causing yellowed plants and leaves. This product unlocks the iron and restores the plant vigor

We use this product a lot as our soil is really bad and trees and rapberries show lack of iron by their yellow leaves. Iron greens them up and doesn't harm the grass around them. Great product and price
