The Andersons Professional Pure Nitrogen 32-0-0
This product focuses on pure nitrogen delivery, with a balanced approach using both quick- and slow-release forms. It’s designed for lawns that exhibit nitrogen deficiencies and can be applied during the growing season to support steady green-up and turf vigor. The formulation is suitable for multiple application types and aims to provide a sustained nitrogen supply to maintain color and growth between feeds. Iron and micronutrients are not typically included beyond the nitrogen framework.
UREA FERTILIZER 46-0-0

The nitrogen content is significantly higher than typical lawn fertilizers, offering a robust option for nitrogen-demanding periods.
Buying Guide: Key Purchase Considerations
- Nitrogen content and release type: High-nitrogen formulations come in quick-release, slow-release, or a blend. Quick-release nitrogen delivers faster greening, while slow-release provides a more sustained feed with fewer applications.
- Application method: Some products include attached sprayers for convenient spot or broadcast application, while others require standard spreader or manual application.
- Coverage and lawn size: Check square footage coverage per bag or per bottle and align with your lawn size to minimize waste and ensure even feeding.
- Soil health features: Some formulas include iron for greening, beneficial microbes for soil health, or humic components to improve soil structure. Consider what benefits your lawn needs beyond nitrogen.
- Grass type and season: Most products work across common warm- and cool-season grasses, but timing may vary by climate and species. A few formulas are optimized for spring and summer usage or for year-long feeding.
- Environmental impact and safety: Follow label directions for storage, application rates, and irrigation to prevent run-off and nutrient leaching. Consider products with environmentally mindful formulations if you have concerns.
In selecting a high-nitrogen lawn fertilizer, consider your lawn’s size, climate, and growth goals. For rapid visual green-up, a higher percentage of quick-release nitrogen may be appropriate, while ongoing turf vigor benefits from a blend with slow-release nitrogen. Iron supplementation and soil microbes can complement nitrogen for deeper color and healthier soil structure, depending on local soil conditions and prior lawn health.
