Best for: High-Nitrogen Granules For Gardens.

Why it ranks #5: The 5-pound water-soluble 46-0-0 urea is positioned for indoor and outdoor flowers, lawns, and vegetables, though its directions call for careful application.

A 46-0-0 analysis makes this Cz Garden Supply urea a concentrated nitrogen choice for indoor flowers, lawns, and garden vegetables.

• Form: Granules

Best for: Nitrogen And Sulfur For Turf.

Why it ranks #6: This granular 33-0-0 formula adds sulfur and is aimed at turf, lawns, gardens, and crops; the listing gives conflicting package weights, so verify the label.

A 33-0-0 formula blended with sulfur distinguishes Supply Solutions Rapid Green from nitrogen-only fertilizers. The product targets turf and lawns, while its description also names gardens and crops; its stated aim of uniform color and steady growth suits users managing larger green areas.

The nitrogen-and-sulfur blend connects the product’s 33-0-0 analysis to its stated goals of uniform color and steady growth. The listing emphasizes turf grass and lawns, including golf-course lawns, while also naming gardens and crops as uses.

10. GS Plant Foods Amino Power

• Form: Liquid

Best for: Plant-Based Nitrogen For Spraying.

Why it ranks #10: Its plant-based amino-acid nitrogen source suits turf, vegetables, fruits, and berries, but the supplied specifications conflict by calling it both powder and liquid.
