    so you are saying it is insoluble and required the bacterial to break it down to make it available?

    I have never really heard of the micronized UP and google foo seems weak today

    I spoke with a JDL rep Yesterday and he told me to look into getting one of their lesco sprayers with Jet agitation?

    Jet is what I have, not the same as mechanical.

    I have a diaphragm pump, not the same as a piston pump.

    I kind of understand what Green Doctor is saying, you are pumping micro particulates in suspension which is abrasive and settles. I would like more info on these specific recommendations.

    I am sure Lesco has fine sprayers but shop around.

    When he says UF, I keep thinking of Uflexx.

    Urea-formaldehyde is what he is saying me thinks

    Yes. The other name for this is Nitroform. Urea formaldehyde powder is water insoluble and can take over a season to be utilized if the particles are the size of a normal granule.

    I have the standard D30 with a jet agitator in the tank. I would not trust it with 25 lb of insoluble material in the mix.

    Growth Products states their methylene urea will last up to 6 months when injected. That is satisfactory to me for a tree.

    I am very happy with the PHC product for trees. I get good lasting responce and the trees are drought resistant too.

    Oh yeah, Dr Green I remember spraying Powder Blue' while at TruGreen,. It was a type of ureaform ground to a fine (insoluble ) powder. It needed paddle agitation. But at times is was so insoluble--there was no noticable green effect. Plugged filters at times. Their salesman must have bought our buyer a couple double martini's. It left a chalky white residue on fences and walks.

    Scotts has used methylene urea for years. Non-burning, can release slow or fast depending on the size of the long chain molecule.

    Good stuff, but be sure you understand how to use it. Needs bacteria--so works slow in cold weather.

    I use a little urea triazone liquid to extend the effect of my AS based fertilizers. No Powder Blue. I rather use more predictable materials. Even coated granules are not predictable enough for me.

    I read the best use of UF is to incorporate a year's worth of N into the soil and use some soluble N to hold the grass over until the UF starts releasing. Do that and one feeding can last a long time.

    I could see a UF Feeding in April to last through the summer ( thinking lawns too here)
    Then using a light AS feeding in April May and June, Bios and Micros only in the Summer. Another dose of AS in Sept then winter feed with K in October.

    I used the AMMO's with methylene urea http://www.growthproducts.com/pdfs/Turf_Ammos_22-0-0.pdf

    I was not too impressed with the color.
