One of the primary nutrients your lawn needs is nitrogen, which is included in almost all major fertilizers on the market. Fertilizers can be quite expensive as most lawns need 4-5 fertilizer applications per season. One of the best kept secrets of lawn care is using Blue DEF as fertilizer for your lawn during the growing season, or during a fall nitrogen blitz.

Now before you immediately dismiss this notion, let’s go over how and why diesel exhaust fluid is by far the cheapest source of pure nitrogen fertilizer that you can put on your lawn.
How Is Diesel Exhaust Fluid A Fertilizer?
BlueDEF diesel exhaust fluid is made of only two ingredients, 32.5% pure urea and 67.5% purified water. Urea is pure nitrogen and is the main nitrogen source in most lawn fertilizers on the market.
This means that diesel exhaust fluid is the purest form of nitrogen you can find, which makes DEF an effective nitrogen lawn fertilizer.
How To Use Blue DEF On Your Lawn
Since Blue DEF is a pure and concentrated nitrogen source, it must be applied correctly or else you can burn your lawn. To apply Blue DEF to your lawn, you’ll need the following:
👉 BUY – Blue DEF Diesel Exhaust Fluid 2.5 Gallon, 2 pack
👉 BUY – 2 Gallon Lawn & Garden Sprayer
👉 BUY – 32 oz Measuring Pitcher
Since Blue DEF is in liquid form, you’ll need to mix it with water in a tank sprayer in order to apply it to the lawn.
Blue DEF Lawn Fertilizer Mixing Ratio:
- 10 oz of Blue DEF per 1 gallon of water / 1,000 square feet
For example, if you have a 2 gallon sprayer, then you’d mix 20 oz of Blue Def with 2 gallons of water to cover 2,000 square feet of lawn.
Pro Tip: Spoon feeding your lawn with nitrogen during the hot summer months can help it stay emerald green and keep it from going dormant.
Don’t Water DEF In After Applying
Since you’ll be giving the Blue DEF mixture to your lawn in a foliar application (liquid fertilizer), your lawn will immediately absorb the nutrients.
This means that you should NOT water immediately after applying Blue DEF as it can essentially wash the nutrients you just applied off of the grass blades. Instead, make sure that the grass has several hours to dry and absorb the fertilizer (we recommend at least 12 hours) before watering.
Why Use Blue DEF Instead Of Other Fertilizers?
The main reason is cost savings. Because Blue DEF typically comes in a 2.5 gallon jug, that means it can treat 32,000 square feet of lawn at a rate of 10 oz per gallon / 1,000 square feet.
There is no other pure nitrogen source on the market that covers that much square footage for the price. If you have a smaller lawn, which most people do, this means a 2.5 gallon jug of Blue DEF can easily last you for an entire season’s worth of fertilizer applications.
Aside from the massive cost benefit, foliar applications work immediately as opposed to using solid fertilizer prills in large fertilizer bags which take days or even weeks to break down and provide nutrients to the soil. This means that by applying Blue DEF as a liquid fertilizer, you’ll see faster green ups and results.
Using DEF On Your Lawn Is A Smart Choice
If you want amazing results without having to spend a lot of money, then using Blue DEF as a lawn fertilizer is one of the smartest investments you can make. Not only will you be able to give your lawn the most important nutrient it needs in order to keep it healthy, but you can get multiple applications out of one jug at a fraction of the cost of solid big-box nitrogen fertilizers.
This makes Blue DEF one of the cheapest high-quality lawn fertilizers available!
