it said poorly drained soil which is similar to boggy soil.
If it was well aerated soil then we would have chosen nitrifying bacteria.

I am confused about the meaning of drainage !! what does it mean ?? :oops:
a poor drained soil means that it has lots of water (water logged soil) so low oxygen content. therefore anaerobic conditions which means denitrifying bacteria is most likely
