Nutrient Availability at varying pH

Some of these I found on hydroponic websites some I found at soil websites. They all look pretty similar to me. Pick your favorite. :smokin:

Great contribution WCQ, thanks for your addition as well MWBM. :cool:

Side by side, soil looks much more forgiving than hyro. :eek:

Yeah Westy, that chart is the reason I went searching the internet. No offense to Stoney, but it isn't very realistic. See how it says P,Ca and Mg are not available below 6.5 in soil. It is the only chart that shows that, none of the others (most of which were on .edu sites) confirm this. Those nutrients become less available, but do not lockout completely at that pH value. :smokin:
