more ?'s on trace elements

[Jim Wilson <freaks at aracnet_com>]

I found this recipe in the archives:

EDTA sodium ferric salt (chelated iron)   40.000g   = 7.70% Fe  7.00%
MnCl2.4H2O   (manganese)                  10.000g   = 4.56% Mn  2.00%
H3BO3        (boron)                       3.000g   = 0.85% B   1.30%
ZnSO4.7H2O   (zinc)                        2.000g   = 0.73% Zn  0.40%
Na2MoO4.2H2O (molybdenum)                  0.250g   = 0.16% Mo  0.06%
CuSO4.5H2O   (copper)                      0.025g   = 0.01% Cu  0.10%
CoCl2.6H2O   (cobalt)                      0.025g   = 0.01% Co  
                                    total 55.300g

Has anyone tried this?  Is it equal to chelated trace elements?
55.3g is 121 lbs, that's a lot!!!  Could quarter it:

EDTA sodium ferric salt (chelated iron)    10.0g
MnCl2.4H2O   (manganese)                   2.5g
H3BO3        (boron)                       0.75g
ZnSO4.7H2O   (zinc)                        0.5g
Na2MoO4.2H2O (molybdenum)                  0.0625g
CuSO4.5H2O   (copper)                      0.00625g
CoCl2.6H2O   (cobalt)                      0.00625g  
                                    total 13.825g
