more ?'s on trace elements
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
