Is that all N with no K or micronutrients? If I applied that little N in a year to zoysia, I and my clients would be looking at pale zoysia that is also eaten up by disease. Especially dollar spot. I usually start with 1/2 lb N spoon fed monthly and at least 1/4 lb K along with a complete spectrum of micronutrients. I have dealt with the funny phone calls because I thought I would cut back on the fertilization during wet periods. I get to explain why there are 1" spots of dead grass all over the lawn and why the grass is yellowish. Topdressing and organic matter is ok, but never do I let political correctness compromise a client's lawn.
No, still need K - I am assuming K is essential even though she did not post any specific information on K that I recall at the event. I would assume that the micros would be important as well as our soils tend to show on test that they are low on several.
Back on topic: I have not seen the negatives of going over what I consider starvation rates of N. By the way some industry savants and the acclaimed researchers talk, my lawns ought to be unmaintainable, near death. But the opposite is true. Could it be that I am using the appropriate N source for the grass and soil chemistry? Or that I apply more than token amounts of K along with micronutrients.
If that's the stuff from Nurseryman's sure-gro, then about $10 per pound of nitrogen is pricey for a turf fertilizer. Go for it if the budget is there.
Actually no. I do not like urea based fertilizers on turf except on acid soils. Also, why is there P in there. My usual for turf is a 20-0-20 or 20-0-10 + micronutrients. The N is ammonium based, the K is potassium nitrate. No chlorides.
Matt, not sure if they sell it, but I buy from Howard. They made it to the exact specs of Broschat.
