Nutrisphere is the cheapest form of stabilized nitrogen that I know of. It last's up to 8 weeks. A lot of the polycoats no longer have any sulfur coating anymore due to cost. I use a lot of UFLEXX & UMAXX products but have used Nutrisphere with preemergent the past couple years. It's ok but maybe switching to a little more longer lasting product next year depending on the cost structure.
