CountryMax Urea Fertilizer 46-0-0 (50 lb) – Fast Green-Up
Best for large lawns or landscape projects requiring rapid nitrogen delivery. The high-nitrogen 46-0-0 formula supports quick top growth and a deep green color across lawns, gardens, crops, trees, and shrubs. This granular fertilizer is suitable for homeowners who manage sizable properties or commercial seasonal programs. A potential limitation is handling a heavy bag and ensuring even spread on uneven terrain. Use with a broadcast spreader for uniform coverage.
CountryMax Urea Fertilizer 46-0-0 (10 lb) – Compact Lawn Booster
Best for smaller lawns or targeted applications, this 10 lb bag provides a controllable option to correct nitrogen deficiencies and support vigorous growth in limited spaces. It’s convenient for spot feeding around edges, patches, or newly established turf. A caution is to avoid over-application in a single spot to prevent burning sensitive roots. Pair with a precise spreader or careful hand-feeding for best results.
Supply Solutions Urea 46-0-0 (40 lb) – Plant Growth Booster
Best for general lawn and garden vigor, this fertilizer focuses on nitrogen supply to support protein synthesis and overall green growth. The 40 lb size makes it a practical option for larger landscape areas or ongoing feeding programs. Use caution to apply evenly and avoid localized high concentrations, which can stress roots. Choose this when you want a reliable, high-nitrogen solution with broader coverage.
Lesco Sprayable Fertilizer 46-0-0 Urea SGN 200 – 50 lb
Best for large areas or where liquid application is preferred, this sprayable 46-0-0 option supports rapid greens and can be applied as a solution. The product is well-suited for lawns with broad surface areas and for those who favor liquid delivery methods. A potential limitation is the need for a compatible sprayer and careful calibration to prevent over- or under-application.

Best for spray-enabled applications where quick dissolution is desired, this 15 lb sprayable grade provides 46% nitrogen with convenience for liquid delivery. It suits larger lawns or professional-style maintenance programs and offers a reliable alternative to granular forms. Avoid this if you lack a compatible sprayer or require more granular control in tight spaces.
TRIPLE SUPER PHOSPHATE FERTILIZER 0-46-0 – Phosphorus for Growth
Best for phosphorus supplementation, this product complements 46-0-0 programs when bloom size or root development is a priority. It targets gardens, lawns, and trees that benefit from additional phosphorus, supporting robust flowering and root systems. Use in combination with nitrogen-focused products when soil tests show phosphorus limitation. It is not a direct substitute for nitrogen-focused lawn feeding.
Cz Garden Urea 46-0-0 (10 lb) – Versatile Indoor/Outdoor Use
Best for versatile nitrogen delivery in both indoor and outdoor settings, this 10 lb bag is convenient for mixed-use feeding across lawns, flowers, and garden beds. It supports quick green-up and is easy to store thanks to resealable packaging. A limitation is that compact bags may require more frequent restocking for larger properties.
Buying Guide: How To Choose The Right 46-0-0 Fertilizer
- Property size and application method: For large lawns, granular options (CountryMax, Supply Solutions) are efficient with broadcast spreaders. For odd shapes or hard-to-reach areas, sprayable formulations (Lawn Synergy) can save time but require proper equipment.
- Delivery method and equipment: Granular products need a spreader; sprayables require a compatible sprayer and calibration to avoid over-application. Consider your setup and maintenance routine when choosing.
- Soil health and nutrient balance: 46-0-0 provides nitrogen but lacks phosphorus and potassium. If soil tests show phosphorus or potassium needs, combine with a phosphorus source (like the 0-46-0 option) and follow soil test recommendations.
- Lawn type and growth stage: Active growth periods benefit from rapid nitrogen uptake. Spot feeding may be ideal for patches, while full-season programs suit larger turf areas.
- Storage and handling: Heavier bags require sturdy storage and careful handling. Resealable packaging (where available) helps maintain product integrity for repeated use.
