Question

What pH is it in soils that stops the activity of most microorganizms?

Answer 1

alkaline.or acid to the extreme .will work.

Answer 2

PH of 5 or above, PH of 8.5 or below.

Answer 3

As was posted either extreme will limit the activity of soil microbes as availability of nutrients becomes less, as is with plants. Higher ranges will the cause death of either. look at graphs on nutrient availability and pH.

Answer 4

ph is hydrogen so highest activity of microorganism's come's from middle of 7 ish or so.  Microorganism's are infinite so if your asking ag question the answer is million's or quadtrillion's of  soil activity.  (at all ph). Ag wise all food (industrial) is all ph level's so your question is moot, but if cellular activity is measureable at all ph in soil's, then you can figure out how much photosynthesis hydrogen ph can stimulate microogranism's.  However if your talking of non ag activity's ph is irrelevant, so your future life as an agronomist or physicist, can absolve it..

Answer 5

pH of 4 or below

pH of 8 or above

Answer 6

Some soil is acidic (pine tree forests) while others is basic (limestone). Microorganisms live in all types of soil, only polluted soil can kill organisms.
