    I switched to a 10-0-20, 65% slow-release, 10% Fe for my first round this year.

    It's absolutely wonderful as all of my yards are a deep green, with very little top growth.

    I was mowing some yards today that I haven't been to for 3 weeks, and was able to get away with just double cutting them, didn't have to bag them.

    In the past I'd been running a 19-0-6 30% slow release, with the Dimension built in, but my god, the top growth I was fighting with the cool season turf, trying to keep caught up on the mowing. I was triple cutting / bagging 1/2 the spring.

    Why would you want to spend you money on such a low N product. If you figure the cost per M just for that product I'll bet it is over 1.00. Buy the most amount of N, with a minimum 30% slow release and you'll pay less per M for the product. If you mow also just raise the slow release percentages up. You can buy a 39 or 37-0-0 100% slow release if you want to go that high.

    Iron is great for high pH soils, but it is short-lived. Manganese, boron, copper, sulfur, etc are also very beneficial for alkaline soils.

    Im with you on the low nitrogen %. I have the same problem here. I try not to put down more than 10% also. Where did you get it?

    The past 10 years i've used a 10-18-20 w/ 1% Fe. Ammonium sulfate will green up your lawn better in colder weather and also leaches less quickly. I know... why the high Phos. It's primarily a winterizer, but would work well for an innitial app in the spring.

    Is that a U-Flexx or SCU Nitrogen source?
