Answer:
You're missing 1 part of the equation, so an answer cannot be reached.

A few insights:
1.) You are NOT applying this material for agronomic reasons. You're applying it for ECONOMIC reasons.

2.) The analysis numbers are meaningless unless you know HOW MUCH NPK you're applying and HOW MUCH you need.

3.) Are the turf shoots or roots growing? Will they be in 7-10 days?

4.) If not, then your CEC (Cation Exchange Capacity) must be above 15 for this application to do any good.

Since you probably don't know the CEC of each lawn and you do not know what the soil needs, you have no idea if your application is sorely needed or a complete waste of time and money.



Bottom line:
If the grass ain't growing AND you don't have a soil test, WAIT.

our soils here lack K and the array of minors average PH is 5.5
I apply for argo and econo reasons ie non irrigated lawns need more spring N because in summer they go dormant But get mowed the rest of the year.
For summer it's a 21-7-14 with formaldehyde urea and PCSCU...
I don't believe in soil tests because my area has a few soils in it and after years you just know, with all our rain and long grow season we don't make that big of a deal over "spring" because we mow in the "winter",too! Once you know your area "averages" save yourself some $$$ and skip the soil tests...
I supplement, liquid Fe8 + Humisolve, over these apps with products that cause allot of top growth, here again our soils are only lacking K and a balanced PH.

Ray --- is the 19-3-6 w/Demension and Anderson fertilizer? What Lesco guage # do you set your spreader at? I assume you do two applications of this in the spring, right?
Just a quick note. If you use Dimension you should need only to apply once. Get a label and read. It will tell you every thing you need to know. As you learned by state testing the label is law.

My Lesco dealer told me to use gauge setting of 15.

They are saying to do it with two applications here in Nebraska... Other posts and posters on this board recommend the same. Am I missing something?

1grnlwn says that because dimension has a longer residual effect than any other pre-emergent used. Its not quite a nessesary, but supposidly it really helps!

up to 12 weeks? vs standard up to 8 weeks.... What happens after the 12 or 8 weeks with the seeds that are still there?

They germinate and then die in the winter.

A summer germinating weed will not get big by fall anyway.

With a thick turf canopy, germination is minumal.

Most crabgrass that will germinate each year will do so (or try to) early. But it DOES in fact germinate all season long.

Ok...
then what happens is we put down 1 application of Dimension starting April 1, soil temps are at about 45-50 when we start and we are done with the applications in 3 weeks?

If we do not do a second application of Dimension how much crabgrass, foxtail etc are we going to see in 12+ weeks and after the 12 or so weeks, the way it's explained by Kent, the crab grass will begin to germinate..?

Is this why we are doing two applications or is it overkill on the introduction of a pesticide?
