- 0.5 lb N → 1 lb of product per 1,000 sq ft
Water in immediately after application. Urea can volatilize if left on the surface and may cause burn if overapplied.

- Beginner lawn programs
- High-heat summer applications without irrigation
- Homeowners unsure of nitrogen math
👉 Use with care—high nitrogen content can burn lawns if overapplied

Greener, thicker lawn
"I’ve been using this for the past 4 weeks to boost my lawns autumn growth and it’s worked wonders. My lawn is greener and thicker than ever. I wish I had some a nitrogen boost sooner."
Q&A
- If using a dial N spray hose end sprayer can you put granules in it or do you have to melt the granules to liquid to apply it to lawn? It seems watering it in will be more evenly.
- This product can be mixed into water for a liquid application. I would recommend using a pump sprayer or backpack sprayer instead of a hose end sprayer for this product to ensure even distribution.
- What to set the Scott's wizz broadcaster
- Maximum recommended rate: 1 lb of nitrogen per 1,000 sq ft per application. 1 lb N → 2.17 lbs of product per 1,000 sq ft 0.5 lb N → 1 lb of product per 1,000 sq ft Please reach out to us via email at support@lawnsynergy.com for more recommendations for your spreader settings.
- Do this product contain a polymer coating?
- 46-0-0 is pure urea without any coating.
- How much water do I need to melt 1lb of 46-0-0 for 0.5lb for 1000sqft
- Water volume is just a carrier — it doesn’t change the nutrient rate, only helps with coverage. The main goal is to apply evenly without burning. Typical spray volumes for soluble fertilizers: 1–2 gallons of water per 1,000 ft² (common for turf spraying). Urea is highly soluble so it dissolves easily in small volumes. So you can safely dissolve your ~1.1 lb of urea in 1 gallon of water and spray that evenly over 1,000 ft². If you want better coverage, use 2–3 gallons.
- Is this 100% soluble, without residue? I want to apply it to fruit trees through a drip fertigation system. Thanks.
- Yes it is. However our 20-20-20 water soluble would be much better since it contains many other nutrients.
