Do you use two apps of ESN per year or just a Spring app?
usually 2 apps but it depends on the conditions mostly on the heat, and how wet it has been. This year I will probably do 3 apps because it has been really wet. This stuff will work a lot longer, and better and grass a lot greener if you core aerate first and let the granules go down into the holes from aerating.
Well, I put down 1000 lbs of Milorganite this weekend, mostly for the greening effect I hope to gain from the iron.
I've been reading on some research from Colorado State regarding higher N apps in the later fall with the idea of having it available in the Spring when needed without pushing excess top growth. I think I'll give it a shot the first of Oct. or so after a good aerating.
Thanks for the idea.
if you are wanting a darker green color lawn the only thing that is going to give you that is higher rates of nitrogen milorgranite is only 5% nitrogen and 4% iron I think. Why not just apply urea nitrogen if you are wanting dark green color with ESN. You can not really have very dark green grass and not have the top growth unless you are using very high percent chelated iron which urea nitrogen and ESN is cheaper plus it gives you a very dense healthy lawn.
I am so dense but what is ESN?
Environmentally Smart Nitrogen, encapsulated urea at 44(?)-0-0, sold by Agrium through CPS for field crops. It's a slow released nitrogen that is released by a function of both water and temperature. It is cheap compared to "turf" fertilizers....I can buy it for $230/ton locally or $.26 per # of N per k, assuming I did my math right....
I went with Milorganite for the Iron content, I'm wary about a lot of nitrogen as the heat of summer should be coming soon. I'm thinking ESN plus aeration and overseeding this Fall.
Next year I think I'm going try an app of ESN in Spring after aeration, followed by Milorganite around Memorial Day and ESN plus aeration and overseeding in September next year. Throw in an app of Prowl for a pre emerge and an app or two of fungicide and I should have a heck of a lawn. Now to get my mower to cut cleanly without double cutting and a striping kit....
My CPS gave me a price of $880 a ton today
