Oct 20 here....had a couple light frosts so far, with more frosts and some freezes this week, and temps below normal. Grass still growing vigorously. Last mowings of the season this week and next. Last fert app going down last week of Oct. Heeding advice on here, maybe 1/2 to 3/4 lb N.

I don't think it will make much difference but I would go with 3/4 lbs if your charging the same rate as your other apps give them there moneys worth.

I do a job and in the contract they tell me how much fert to put down the 4th treatment (now) gets 1 1/4 lbs of N.

I would go no more than a 1/2 lb considering that 50% won't get used anyway.

Still not sure I am sold on minimal to no utilization after Oct 10th thing.

So who has done testing on this side by side...to confirm or deny this...?

The University of Wisconsin turf department has done the testing. They have the results. Look up Wisconsin Turf Association. The publications are there. And DA, why don't you believe it? I have done it for the past three years and my lawns look no different than they previously did when I applied fertilizer up to Holloween.

Repeatable experimentation and unprejudiced observations are part of the scientific method.

It does make total sense that warmer temps and turf actively growing makes a difference. This was discussed on another thread and I remember reading the referenced article. What was the professors view on heavy vs light application?

Just curious if you put down 60% of the seasons nitrogen after the summer heat has let up...?

I do push a fairly green lawn even during the summer but all of these accounts are mowed at 3.25" and above. The ones mowed in the range of 3.75"- 4.5" grow like a weed in the summer heat as long as watering is dialed in and heavy 2-3 times per week only.

Always looking for a better way.

So why don't we put down a 1/4 lb and not waste any ?

I'm sure that Oct 10th date is not a hard and fast date...what I would like to know is what weather/soil/turf conditions indicate that you should start winding down your fert apps for the season?

I suppose you could do that. What I remember is that after Oct. 1 the utilization rate of nitrogen starts to fall off pretty fast. I would assume it is due to the soil temperatures and amount of sunlight the plant is receiving. That is why if I am running late I will apply ammonium sulfate at no more than a 1/2 lb. Our soils are pretty high in PH anyway so the turf utilizes it pretty fast and it turns a real nice green.
