pH outside...

I was just wondering is monitoring the pH important if you're growing outside in a ground or is it just as important as watching the pH of weed in a pot? I was wondering because being outside with all the natural stuff going on and the plant having more than what a pot allows for the roots, it'd be a little bit less responsibility on me for stuff like that.

soil ph is important but probably not checked by most outdoor growers and chances are you will not have any problems, if the soil is half way decent to begin with, but if the plant is showing signs of a deficiency or not growing well it may be worth checking as it could be the main cause of the problem.
