    It can be done. I figured out the formula. I'll make it easy for you Lesco.

    If Biosolids is 4-2-0, then a 40# bag of 15-3-7 is 20# of Bio, and 20# of 26-4-12. I tried to determine if this is a "maxed out" product (no filler) based on the raw materials. It seems to be pretty darn close.

    excluding adding micros (Iron, Manganese) that are not in the Biosolids, blend the following for a 40# bag...

    20# 4-2-0 (Biosolids)
    6.5# 39-0-0 (PPSCU)
    5.5# 46-0-0 (Urea)
    1.75# 18-46-0 (Diammonium Phosphate)
    6.25# 0-0-50 (Sulfate of Potash)

    will yeild... 15.45 - 3.01 - 7.81 or...

    15-3-8 , 50% Biosolids, 50% PPSCU, SOP. whataya think?

    I'm considering getting the raw materials and making it myself. The guys at lesco said if I bought 6 or more skids, that it could be customed blended. Unfortunatly, I don't need that much yet.

    You may want to check out 7-2-12 from Nutrients PLUS, we use it up here for K applications, and poultry and biosolids are the organic matter portion.
    Hit me up with any questions about it.

    I also do not buy from lesco because all they use is MOP.
