10 Best High Nitrogen Lawn Fertilizer 2026 in the United States

Scotts Green Max Lawn Food is designed to improve your lawn's greenness quickly thanks to its 27-0-2 N-P-K ratio, featuring a high nitrogen content (27%) which promotes lush, green grass growth. It also includes 5% iron, helping your lawn turn green faster without leaving stains on nearby surfaces like driveways.

This fertilizer is easy to use with granules that can be applied directly to various grass types in spring, summer, or fall. You or your pets can safely walk on the lawn immediately after application. The product provides quick visual improvements and covers a large area (10,000 sq. ft. per bag). However, it has a basic formula without a controlled release mechanism, so nutrients may wash away faster during heavy rain.

With very low phosphorus and potassium levels, this lawn food mainly focuses on greening rather than overall soil health or root development. It is an excellent choice for fast, vibrant results on established lawns during the growing seasons but might require additional products if your soil needs more balanced nutrition or slow-release feeding.

The Maximum Green & Growth High Nitrogen 28-0-0 Lawn Food is a liquid fertilizer designed to boost lawn health with a strong nitrogen content, which is essential for rich green color and vigorous growth. Its N-P-K ratio is 28-0-0, meaning it focuses solely on nitrogen without adding phosphorus or potassium, making it ideal if your lawn mainly needs nitrogen. It combines 70% quick-release nitrogen for fast effect and 30% slow-release to maintain feeding over time, which can help keep your grass healthy between applications. The liquid form is easy to apply using a hose-end sprayer, covering up to 12,800 square feet, making it convenient for medium to large lawns. It's suitable for all common warm and cool season grasses, which adds to its versatility through spring and summer. Being made in the USA by an experienced family business may appeal to those valuing domestic production.

Since it lacks phosphorus and potassium, it won’t address other nutrient deficiencies that some lawns might have. Also, as a concentrated liquid, careful mixing and application are needed to avoid overfeeding or lawn burn. If you’re looking for a straightforward nitrogen boost and know your lawn mainly needs that nutrient, this product fits well. For lawns that require a more balanced fertilizer or have specific nutrient needs, considering other options might be preferable.

Scotts Turf Builder Lawn Food is designed for all grass types and covers a large area of 15,000 sq. ft. Its N-P-K ratio is 32-0-4, which means it has a high nitrogen content and very low phosphorus and potassium. This high nitrogen level helps promote lush, green growth and strong roots. The product is in granule form, which makes it easy to apply by spreading it evenly over the lawn, whether it’s wet or dry.

You can use it in spring, summer, or fall, offering flexibility for multiple growing seasons. It is pesticide-free, so it focuses on feeding and strengthening the grass naturally. Since it contains zero phosphorus, some lawns might require additional nutrients depending on soil conditions, making a soil test beneficial before application. The nitrogen content provides quicker effects but may not last as long as slow-release formulas, potentially necessitating more frequent applications.

Scotts Turf Builder is a solid choice for those wanting a straightforward, high-nitrogen fertilizer to improve lawn health and root strength across various seasons.
