  • It is supper mixture or mixture of mixtures.
  • 34 elements present in it.
  • 13 elements are universal. e.g. C, H, O, N, P, K, S, Cl, Na, Ca, Mg, Fe, I

(i) Macro elements - C, H, O, N         95%

(ii) Micro elements - 4.24%, Ca is maximum, Fe is minimum

(iii) Trace elements - 0.76 %, B is maximum, Ni is minimum, These are must for activity of enzymes.
