Milorganite vs Ironite – Difference and Comparison

When it comes to taking care of your lawn, you’ll mostly look at the color to determine if it’s healthy or not. Generally, green lawns look healthier than those with a lighter color, but water and sunshine aren’t enough to keep your lawn healthy. The Ironite and Milorganite are products that will help your lawn achieve that healthy green look.

While both products will provide your lawn with a sufficient amount of iron without burning it to keep it looking green, they work in different ways, serve different purposes, and made with different formulas.

Milorganite is a nitrogen fertilizer that contains iron and some micronutrients to nourish the soil and the nitrogen is organic and won’t burn your lawn. Ironite isn’t a fertilizer but it contains lots of nutrients like iron that will help promote healthy grass growth.

Apart from the different micro-nutrients, Ironite has a formula that specializes in iron that helps to boost and synthesize proteins more efficiently to help in photosynthesis and the production of chlorophyll.
