Sunniland Professional Liquid Concentrate 28-0-0 comes in 1 gallon and 2.5 gallons sizes. This Nitrogen product, N-Sure, is unique in that it provides foliar absorption and soil absorption with very low burn potential.
Urea-triazone is a slow-release N fertilizer containing 28% total N. Foliar absorption happens within an hour or so, therefore you can water this in after with ¼” of irrigation or rainfall.
Do not mix with products containing iron. It is best to apply this product stand alone.
Application rates are 3-4 oz/1,000 sq ft or up to 6oz/1,000 sq ft for severe deficiencies.
At the 4oz/1,000 rate, 1 gallon will cover 32,000 sq ft
All rates are to be mixed with minimum 1 gallon of water. For example, if you are applying 28-0-0 N-Sure at the 4oz/1,000 rate, you would mix 4oz of concentrate into 1 gallon of water in a pump sprayer and apply that evenly across 1,000 sq ft of lawn area. You could also use the Ortho-Dial-N-Spray which will put out enough water by default.
