Thanks Brookview for the post. Riggle, we blend a variety of Duration types along with 8% of the nitrogen from Ammonium Sulfate to achieve a kick out. One AP is designed to achieve a color response throughout the year and most importantly after itís first applied. After the ground temperatures increase along with a little soil moisture the Duration will begin to take over. Go to the Spread it and Forget it website for details.
