Know before you buy
Nitroform 39-0-0 uses a urea-formaldehyde composition that requires soil microorganisms to break it down. This biological process releases nitrogen gradually over 8 to 12 weeks, ensuring your plants receive a steady supply of nutrients rather than a sudden, potentially harmful surge.
Yes, the non-burning formula is designed to be safe for a wide range of plants, including lawns, vegetables, trees, and shrubs. Because the nitrogen is released slowly, it significantly reduces the risk of fertilizer burn compared to quick-release synthetic options.
No, this is a nitrogen-only fertilizer with a 39-0-0 NPK ratio. It is specifically formulated to promote vigorous foliage growth and greening, making it an ideal choice if your soil already has sufficient levels of phosphorus and potassium.
You can apply this product using standard broadcast methods or as a soil drench. The granules are uniform and dust-free, which makes them easy to distribute evenly across your garden beds or lawn.
Because of its slow-release nature, you only need to apply this fertilizer once every 8 to 12 weeks. This extended feeding cycle helps you maintain healthy growth while reducing the total number of applications required throughout the growing season.
