    We are trying to use liduid fert on round 2 only for the fact that we can mix the fert with the herbicide we are spraying. We are using an agriculture 28-0-0. works great but settles out over the day and burns the lawns. when the tank is empty there is a thick paste on the bottom. is meckanical agitation the only answer? is there a product availabe that suspends well enough for jet agitation?

    Any help is greatly appreciated!!

    Thanks,

    Joe

    I've never used liquid fert, I understand from alot of pros that grandular covers better, however I wonder if your problem may be in mixing the two chemicals together? I know sometimes this can cause problems. I would check to see if you can do it without an adverse reaction (since I guess in a way you're changing the chemical make-up). Any other ideas guys? It's just a thought.

    We use a product called ferromec from PBI Gordon at about 2 quarts to 100 gallons. it is about 18 bucks per 2.5 gallons, has a 15-0-0 rating, and ALOT of iron in it. it works well, but I also put down grannular, albeit less. Dave

    Try doing the quart jar test. Mix your products together in a quart jar, shake em up and see if you get a precipitate. If the chemicals react, it will usually happen quickly. If you get sludge at the bottom after a while, it may be that you are trying to suspend too much material in the solution. If this is the case, try using less fert, and see if the problem goes away. Adjust your walking speed accordingly, and you should still put down the same amount of fert.
    Agitation can be as easy as running a secondary pump (12v will probably do). Plumb a line out of the bottom of the tank to the pump, and then back in the top of the tank. You may have to be careful about foaming if you do this, but antifoaming agents are available.

    Hope this helps.

    I HAVE USED ALOT OF LIQUID FERT, AND BELIEVE ME, YOU
    WOULD BE BETTER AVOIDING IT. I KNOW IT SAVES TIME, BUT
    IT DOES HAVE A BURN POTENTIAL,IT DOES HAVE RUN-OFF
    POTENTIAL,IT IS EXTREMELY CORROSIVE TO YOUR EQUIPMENT.
    JUST STICK WITH GRANULAR FERT. MOST PEOPLE SEE IT AS
    SUPERIOR TO LIQUID. MOST PEOPLE SWEAR BY SCOTTS, A
    GRANULAR PRODUCT. THE BIG COMPANIES USE LIQUID BECAUSE
    IT IS CHEAP. SHOW THEM YOU ARE CONCERNED WITH QUALITY.

    Get the lables for the two products and read them. There will be compatability information on it. You know from your certification class that if you are mixing and applying these chemicals against the label it is a violation of Federal law. You are opening yourself up to all kinds of legal problems.

    The lable usually also will indicate the jar test that Urban Earth mentioned.

    Mow Ed is very correct, it's federal law that you are agreeing to follow the directions, use on only what it is might to used on, etc., any deviation from the label open you up to heavy fines if something goes wrong.
