mixing powders

     Folks - 
     I have finally assembled the ingredients for a fertiliser recipe. I 
     don't have a ball mill (which I understand to be the best way of mixing 
     powders) and am reluctant to mix the whole lot into one 25 litre 
     solution for reasons of storage, decompostion etc. However, the single 
     solution method would at least ensure that the ingredients are mixed to 
     a farily high level of consistency. I have thought of mixing the powders 
     together in the food processor but this idea does not delight my 
     partner. Can anyone suggest a way to mix the powders to a reasonable 
     Thanks IA, Chris.
