   We have been putting down 1.9 lbs of N per season on our bermuda fairways (quickstand) the last few years, and that has been it. Due to some grub issues we are looking at another product with Acelepryn but that fertilizer will only provide 1.35 lb. of N.
   
   My biggest concern is in my opinion we weren't putting enough N before and now we are going out with less, what should be a minimum amount of N, I would think in our area 2.5 or 3 lbs. Your thoughts?
   
   Also if we were to spray primo on fairways, would this maybe help with a lower amount of N due to a little bit slower growth?
   
   Also we haven't been using any K or P either.
   
   Thanks for your thoughts,
   Mel

   Fertilize until you see response you need. Used to throw close to 4 lbs on Vamont and horrible soils about a decade ago. Diligent fertility and nutrient applications with good solid agronomic and cultural practices I get a better response with only 1.6 lbs last year(more on some weak roughs). I do go higher on our tees because we collect clippings. They were around 2.3 lbs last season.Depends on species/cultivar, weather, length growing season, soils, expectations, rounds, collecting clippings, etc. If you suspect it won't be enough, chances are it isn't. Do you have the ability to supplement with another application? I'm wondering how low I can go. I think I'm approaching the threshold but will try to go lower this year. By the way, most of my N is from organic (biosolids) so I'm still seeing release from previous applications.

   1.9 all year? Wow, I guess you have a really short growing season. I target 1lb / month.

   Mel,
   
   I would go for the primo because it will lower your N requirment (not to 1.9) and give you a much more dense stand of bermuda with fewer clippings. Win, win, win. In Springfield, I would consider putting down a granular a 2-3 times and spray the rest with your Primo. Look at Helena's Coron, UFlexx, or simple Urea in the tank.
   
   I would say 1.9 is on the very low side....
   
   Good luck

   Where did you get this information? from every class or seminar I have been to they always tell you that using Primo does not substitute for nitrogen, you have to continue your fertility practices? Just curious where the new information comes from is all.
   
   For fairways I would plan on 1lb/n per month of the growing season. Now I will say that I had my course on a 4 application plan which done great even though we are green 8-10 months of the year. Now with no budget I am lucky to get one application.

   Mel,
   
   I am very lean on N on my bermuda also, around 2 lbs a year. I spray Primo throughout the season with some N in the tank and fertilize once or twice with granular Uflexx. They are lean but havent had any complaints, still hold color and save me on having to mow as often and less clippings. I dont put down any P or K either. Im at a municipal course in OK with a small budget, more N means more money that I dont have.

   Mike,
   
   Thanks for that info. I wonder if your split apps of U-Flexx gives you a little bit better response then us plus including the Primo. We were putting our 1.9 lb. N down in March before our growing season due to the pre-emergent part of the application. It was 100% slow release. We are going to spray our pre-emergent this year, and push out the nitrogen app until late spring. I do agree we have been able to get away with two mowing's per week on fairways with no complaints. Where we push our tees we have to mow three times per week.
   
   I wonder if there are long term consequences of not applying some K and also having low levels of N? Another issue we do have is areas of clover. I wonder if part of that is from the lack of Nitrogen? Of course spraying it out is our option. I wonder if the Primo will help with that issue as well?
   
   Any issues of winter kill, and or does it matter when we can push those areas closed anyway?

   Mel,
   Yes, 1.9# N/M per season is on the low side. You really want 1# N/M per month of the bermuda growing season. You can get by with a little less but you stated that you had a lot of clover. Clover is an indicator weed showing that you are lacking N. The clover can fix its own N from the atmosphere.

   Mostly from experience with my bermuda fairways on sand. I would bet you a $100 that you would see no difference in your fairways if you put down .6# of an at least 50% controlled release each month and put 1/10# Urea in the tank with your Primo (at least 8oz/A) sprayed two weeks after your granular application.
   
   Iv'e seen it done with as little as 4#/year in Houston where the grass grows from March until October. Would I do it that way, not unless I had to. I would target closer to .75#/month, watch my clippings, organic buildup, and weather patterns and adjust accordingly.
