The effects of nitrohumic acid on root elongation and root activity were investigated Elongation was promoted by sodium nitrohumate even as 0.08% solutions; this was due to an increase in cell elongation. Ability to oxidize alpha -naphthylamine and O2 uptake of roots increased on a /root basis after treatment, but decreased when expressed on a DM basis.Other references
