# Nitroform Fertilizer 39-0-0 Slow-Release Nitrogen Fertilizer

### Nitroform 39-0-0 Slow-Release Nitrogen Fertilizer

Achieve steady, season-long growth and vibrant green color with **Nitroform 39-0-0**, a premium, highly concentrated slow-release nitrogen fertilizer. Built on advanced urea-formaldehyde (methylene urea) chemistry, this granular formula is designed for sustained feeding without the risk of overwhelming your plants or turf.

#### The Slow-Release Advantage

-   **Consistent 8-to-12 Week Feeding:** Delivers a potent 39% total nitrogen. Because roughly 73% of this is water-insoluble, it relies on soil microbes to gradually meter out nutrients over 2 to 3 months, rather than washing away with the first rainfall.
    
-   **Low Burn Risk & Reduced Leaching:** The microbe-dependent release mechanism means you can apply at recommended label rates with an exceptionally low risk of fertilizer burn, keeping nitrogen in the root zone where it belongs.
    
-   **Highly Versatile:** The perfect slow-release nitrogen base for turf, trees, shrubs, container nurseries, and landscape ornamentals. Its clean, granular form also makes it ideal for easily blending into custom fertilizer mixes.
    

#### Easy Application Guide

-   **How to Apply:** Spread granules evenly over the soil surface. Take care to keep granules off plant trunks and stems.
    
-   **Activation:** Water deeply within 24 hours of application to begin the breakdown process.
    
-   **Optimal Conditions:** Because this product relies on microbial activity, release performs best when soil temperatures are above **55°F**.
    

#### ⚠️ Important Usage Notes

-   **Not a Quick Fix:** This is a sustained, maintenance-feeding formula. For rapid green-up or quick nutrient correction, pair this product with a quick-release nitrogen source.
    
-   **Soil Application Only:** This product is **not** water-soluble. It should never be used for hydroponic systems or foliar spraying.
    

#### Quality & Safety You Can Trust

-   **CDFA Registered:** Complies with strict agricultural and environmental standards.
    
-   **Third-Party Lab Tested:** Independently tested for heavy metals, with results consistently and safely well below required regulatory limits.
