Best Nitrogen Rich Fertilizer For Lawns: Liquid and Granular Picks

#1 · Best Overall

1. Petramax Liquid Nitrogen

• Form: Liquid
• Weight: 2 lb

Best for: Two-Speed Liquid Nitrogen Feeding.

Why it ranks #1: Its 28-0-0 liquid formula combines 70% quick-release and 30% slow-release nitrogen, making it a direct fit for spring and summer lawn feeding.

PetraMax combines 70% quick-release and 30% slow-release nitrogen in a 28-0-0 liquid formula, pairing rapid green response with continued feeding between applications. That makes it a spring-and-summer option for lawn owners who want nitrogen-focused liquid care and can dilute the product with water before spraying.

The 28-0-0 analysis centers the formula on nitrogen, and its two release speeds offer different feeding timelines: quick-release for rapid green and growth, slow-release for ongoing growth between applications. The directions specify diluting the product with water and spraying the mixture on the lawn, so buyers need a separate mixing and spray step. The listing describes it as spring-and-summer lawn care, making seasonal timing and the dilution workflow relevant when choosing it.

Skip it if you want fertilizer applied directly through an attached sprayer; Simple Lawn Solutions Maximum Green & Growth includes one and lists its application coverage.

Choose this for spring or summer lawn care when a 28-0-0 liquid and two-speed nitrogen release match your needs. Account for the required dilution and spraying step before selecting it for your routine.

#2 · Best Attached Sprayer

2. Simple Lawn Solutions 28-0-0

• Form: Liquid
• Weight: 2 lb

Best for: Sprayer-Ready Spring Feeding.

Why it ranks #2: The 28-0-0 liquid includes an attached sprayer and covers up to 3,200 square feet, with quick- and slow-release nitrogen in one product.

An attached sprayer applies this 28-0-0 liquid fertilizer at the product’s intended lawn-application ratio, making it a practical option for homeowners who want to feed without a separate mixing step. Its blend combines quick- and slow-release nitrogen, supporting both an initial green response and continued feeding between applications.

The formula contains 28% nitrogen, which the listing associates with lawn color and growth, and the attached sprayer covers up to 3,200 square feet. That pairing gives buyers a ready-to-apply workflow with a stated coverage area for planning a treatment. The blend is 70% quick-release nitrogen for a faster nutrient response and 30% slow-release nitrogen for continued feeding between applications. It is listed for spring and summer use and any grass type.

Skip it if you need a granular fall feeding plan; GreenView Fairway Formula Fall Lawn Fertilizer is specifically positioned for pre-winter lawn preparation.

Choose this for a spring or summer lawn treatment when an attached sprayer and mixed-speed nitrogen release suit your routine. Its listed coverage is up to 3,200 square feet, so account for lawn area before applying.

#3 · Best Long Feeding

3. Jonathan Green Veri-Green

• Form: Granules
• Weight: 45 lb

Best for: Long-Release Granular Lawn Feeding.

Why it ranks #3: Its 29-0-3 granular formula includes iron and provides gradual nutrient release for up to three months, for buyers seeking extended feeding.

Jonathan Green Veri-Green pairs a 29-0-3 analysis with iron for deep-green color and gradual nutrient release for up to three months. That combination suits lawn owners seeking a granular nitrogen treatment with a longer stated feeding window, rather than a quick-release-only product.

The listing says the fertilizer usually yields rich-green color within 7–14 days, while gradual, consistent release feeds lawns for up to three months. Those timing details help buyers weigh visible greening against longer feeding duration. Its 3% potassium is also identified as helping lawns recover from summer heat and prepare for harsh winter conditions. Directions call for a rotary, drop, or handheld spreader on a dry lawn in spring or fall, but not when the lawn is stressed by heat and drought.

Skip it if you need to feed a lawn currently stressed by heat and drought; the directions specifically advise against applying this product in those conditions.

This suits lawn owners seeking granular nitrogen feeding with iron, potassium, and a stated release period of up to three months. Apply only within its listed spring or fall guidance, avoiding lawns stressed by heat and drought.

#4 · Best Multi-Nutrient

4. PetraMax Neighbor’s Envy

• Form: Liquid

Best for: Multi-Nutrient Liquid Lawn Care.

Why it ranks #4: This liquid formula lists 20-0-2, 2.5% iron, and humic acid, adding nutrients and soil amendments beyond nitrogen alone.

A seven-nutrient liquid formula brings nitrogen, iron, humic acid, and other listed ingredients together in one lawn treatment. That combination suits homeowners seeking more than nitrogen alone: the product specifies 20-0-2, 2.5% iron, 3% humic acid, plus fulvic acid and sea kelp in its ingredient information.

The 20-0-2 analysis supplies nitrogen and potassium, while the listed 2.5% iron is associated with deep green color and 3% humic acid is described as enriching soil. Fulvic acid and sea kelp are also included in the ingredient information, giving buyers a single liquid product with several named components rather than a nitrogen-only formulation. The listing identifies coverage of 16,000 square feet for the one-gallon container, useful for planning a lawn-wide treatment.

Skip it if you want a ready-to-use attached-sprayer product; Simple Lawn Solutions Maximum Green & Growth includes an attached sprayer and states its coverage.

This fits lawn owners who want a liquid treatment with nitrogen, iron, potassium, humic acid, and other named ingredients in one formula. Check your application setup, since the listing does not identify an included sprayer or tool.

#5 · Highest Nitrogen Blend

5. Supply Solutions Rapid Green

• Form: Granules
• Weight: 25 lb

Best for: High-Nitrogen Turf and Garden Use.

Why it ranks #5: The granular 33-0-0 formulation adds sulfur and is explicitly positioned for turf and lawns, suiting buyers seeking a concentrated nitrogen blend.

The 33-0-0 analysis pairs a strong nitrogen focus with added sulfur, giving turf, lawns, and gardens a fertilizer aimed at fast green growth. Supply Solutions lists it for lawns, turf grass, golf-course lawns, crops, and gardens, so it serves buyers tending more than a standard home lawn.

The listed 33-0-0 formula centers on nitrogen for leaf growth, while the product description says added sulfur supports uniform color and steady growth. Those features make it relevant to buyers caring for turf or garden areas who want a nitrogen-rich granular fertilizer with sulfur in the blend. The listing identifies ammoniacal nitrogen and urea nitrogen among its ingredients. Its granule form means lawn application involves distributing solid fertilizer rather than spraying a liquid.

Skip it if you need a stated coverage figure to plan a treatment; Simple Lawn Solutions Maximum Green & Growth lists coverage up to 3,200 square feet.

This suits buyers managing turf or garden areas who want a granular 33-0-0 nitrogen fertilizer with added sulfur. The supplied listing gives no coverage area, so it may not answer precise application-planning needs.

#6

6. CountryMax Urea 46-0-0

• Form: Granules
• Weight: 50 lb

Best for: Concentrated Urea Nitrogen.

Why it ranks #6: Its listed 46-0-0 analysis gives it the highest stated nitrogen percentage here, though the supplied details identify it only as granular urea.

A 46-0-0 analysis makes CountryMax Urea Fertilizer the most concentrated nitrogen formulation identified in this roundup’s supplied product details. The listing names urea as the fertilizer and presents it in granular form, a straightforward option for buyers specifically seeking a high-nitrogen product.

The title identifies 10-pound packaging, while the specifications list granular form and model 704; the supplied additional description states Urea Fertilizer 46-0-0. Together, those details identify a nitrogen-focused granular product rather than a multi-nutrient blend. Buyers looking for a particular lawn coverage area or application schedule will not find those details in the supplied listing information, so they should not infer treatment rates from the analysis alone.

Skip it if you want a stated seasonal lawn plan and coverage; Scotts Turf Builder WinterGuard Fall Lawn Food lists fall use and application guidance.

This fits buyers specifically seeking granular urea with a 46-0-0 analysis. The supplied details do not give lawn coverage or application directions, so it is a poor match when those planning details are essential.

#7

7. Scotts Turf Builder Lawn Food

• Form: Powder
• Weight: 12.5 lb

Best for: Flexible-Season General Feeding.

Why it ranks #7: This granular lawn food is suitable for any grass type and can be applied in spring, summer, or fall, but no nitrogen analysis is provided.

Spring, summer, or fall application makes Scotts Turf Builder Lawn Food a flexible choice for homeowners who want one listed feeding option across the growing season. Its lawn food is suitable for any grass type and is described as strengthening grass while building deep roots.

The ability to apply to a wet or dry lawn gives users flexibility around lawn conditions, while the spring-through-fall timing offers more seasonal range than a fall-only formula. The listing says the product builds strong, deep roots and improves the lawn’s ability to absorb water and nutrients compared with an unfed lawn. It is pesticide-free and available in powder form, making it a solid-form treatment rather than a liquid spray; follow the product directions for application.

Skip it if you want fall-specific root preparation after summer damage; Scotts Turf Builder WinterGuard Fall Lawn Food focuses on that seasonal use.

Choose this for general lawn feeding when flexible spring-through-fall timing and wet-or-dry application matter. It suits any grass type, but buyers seeking a spray-on liquid should choose a product listed in liquid form instead.

#8

8. GreenView Fairway Formula Fall

• Form: Granules

Best for: Fall Repair and Root Support.

Why it ranks #8: Its granular formula targets fall lawn care, with steady greening and root growth, but the listed details do not give a nitrogen percentage.

Fall-focused feeding is the defining advantage of GreenView Fairway Formula: its listing says it helps repair summer damage, prepare lawns for winter, and promote a better spring lawn. The granular fertilizer is intended for any grass type and emphasizes steady, even greening rather than surge growth.

The product pairs seasonal fall use with claims of deep root growth, thicker growth, and brilliant lawn color, giving homeowners a treatment aimed at both recovery and pre-winter preparation. Its granular form suits spreading over a lawn, and the listing describes steady, even greening without surge growth. It is also identified for one-time use when seeding a new lawn area; the safety information says not to hand spread, so application should follow the product directions.

Skip it if you need a liquid nitrogen treatment for spring or summer; PetraMax Liquid Nitrogen Fertilizer 28-0-0 is listed for those seasons.

Choose this granular formula for fall lawn recovery, winter preparation, or the listed one-time use when seeding a new lawn area. It is not a hand-spread option, so plan to apply it according to its directions.

#9

9. Scotts Turf Builder WinterGuard

• Form: Granules
• Weight: 8 oz

Best for: Small-Yard Fall Preparation.

Why it ranks #9: This granular fall lawn food supports root development and summer-damage recovery, but its provided details do not specify a nitrogen analysis.

Scotts Turf Builder WinterGuard targets the transition from summer damage to winter preparation: its fall lawn food is described as helping grass recover from heat, drought, and activity while building deep roots for next spring. The listing also identifies this 10-pound product for any grass type.

The fall-only timing gives homeowners a clear seasonal window, and the product can be applied to either a wet or dry lawn. Its stated role in summer recovery and deep-root building connects current lawn stress with preparation for winter and the next spring. Scotts spreader settings are provided for broadcast or rotary and drop spreaders, which can help users set up application. The listing specifically notes use for smaller yards, including spreading fertilizer, seed, and other lawn-care products.

Skip it if you need fertilizer for spring, summer, or fall application; Scotts Turf Builder Lawn Food is listed for all three seasons.

This is a fit for smaller-yard owners planning a fall application after summer stress and ahead of winter. Its seasonal focus is the key boundary: choose another Scotts lawn food for feeding across spring or summer.

#10

10. TPS Nutrients High Nitrogen

• Form: Liquid

Best for: Compact Liquid Turf Boost.

Why it ranks #10: It is described as a liquid high-nitrogen lawn fertilizer, but the supplied information gives no NPK analysis, coverage, or release details.

A compact eight-ounce liquid format makes this TPS Nutrients fertilizer an option for buyers seeking a high-nitrogen boost for residential lawn care. The listing emphasizes greener color, dense coverage, and vegetative growth, connecting its nitrogen focus to the leaf and blade development that creates thicker turf.

The product description links nitrogen with leaf growth, while its feature list says the formula supports blade development and dense lawn coverage. That makes it a focused choice for residential yards and landscaping routines centered on turf growth. Its liquid form distinguishes its application format from granular lawn foods, though the supplied listing does not state a coverage area or application method. Buyers can assess the small listed 8-ounce size, but should not assume a specific dilution or treatment range.

Skip it if you need a stated lawn coverage area and an attached sprayer; Simple Lawn Solutions Maximum Green & Growth lists both sprayer use and coverage.

This suits buyers seeking a compact liquid fertilizer for residential turf and vegetative growth. The supplied details do not state coverage or application instructions, so it is a limited fit when precise treatment planning is essential.
