At 50#'s of urea per 100 gallons of water makes............0.5 lbs./N/K.
That is a light mixture for 250 gallons. Must be using it often with the applications to ensure no burn!!

PM me and discuss more with me!!

I'm in Wisconsin.

Thanks!

Idealy you're better off doing a dry granular fetilizer application and a liquid weed control app. That is ideal. But if you are going to mix the 2, there are 2 ways: Dry and liquid. They each have their drawbacks and benefits.

Dry granular is probably the id4eal way to fertilize, as that the best way to put down slow release fert.(mixed with fast release). But, dry granular weed control applications are not nearly as effective as liquid. You usually have to get the dry weed control to stick to the weeds. Good luck with Wild onions and clover and oxalis!

Now an all liquid application of fert and weed control would work well at controling weeds as long as you get the spray onto the weeds. But the liquid fertilizer can easily be over applied in some areas, so you have to be careful. When you use a spreader to apply dry fert, you can simply follow the wheel marks left by the spreader to determine where to run the next pass with the spreader. Thats not easy with liquid, so if you put too much in 1 spot, it might stress it or kill it. If you miss a spot, it will stripe the lawn!

Best bet is to buy a good broadcast spreader and a 'good' backpack sprayer for weed control.

When doing liquid,i liked the 3 gal nozzle ,it gave a nice easy pattern. The trick is to start about 3 ft from the line and pick a spot at the end of you walk. Then on the turn round same thing ,this way you get a nice even patten going both ways,

On new customers and people with bluegrass sod lawns, we used to put down 4.5lbs of 16-5-10 w/Team, and 1lb 46-0-0 per 1000 sq/ft!

On existing clients who got a late fall service the year before of 1.5 lb 46-0-0 and 1 lb 0-0-60 per 1000 sq/ft, we'd only apply the 16-5-10 w/Team at 4.5lbs per 1000 sq/ft.

That was back in 1988-1991.

TooMuchClay, that's interesting. In the past I've always done granular fertilizer in the spring and fall. Never really applied any weed control applications on a consistent basis. I just looked at the cost analysis on the liquid weed and feed versus buying granular....Saving about $150 with the liquid, but granted it has it's drawbacks, namely not slow release. Do you think I could stilll get away with liquid weed and feed in the spring and granular in the fall, or would you suggest, even with the big price difference, to put granular down in the spring and fall, and use liquid weed control? As far as straight weed control, do you recommend 2-4D?

There are a lot of new weed control products out these days, so I'd recommend getting a free PBI Gordon catalog and looking through it. There are now better options for cool weather weed control and hot weather weed control than before. There are also non 2,4-D weed controls that seem to work well at times.

I dont know the price of liquid weed control from a quantity basis as I've never priced it, and maybe they have now inproved it for better slow release performance. I just like the ease of application of granular and the knowledge that good granular fert will have good slow release results. But if all things are equal and you dont have trouble applying liquid, AND its cheaper, then maybe thats the way to go.....

Just be careful not to spray any fert/weed control mixture onto ornamental plants!

Thanks for that info. I just contacted PBI Gordon for a catalog.

I'm throwing around the idea of this fertilizer and weed control process:

early May: liquid weed and feed
middle June: granular fertilizer
late September: fall (liquid) weed control
mid October: fall (granular) fertilizer

What do you think?

I typically do the 'winterizer' during Sept, and sometimes have a late season fert in Aug, depending on the weather... then,,, do the weed killer in Oct., when the plants are really busy sucking everything into their roots for winter storage... the store the 2,4d as easily as sugars...
