This article provides notes on the buffering of soil. Buffering refers to resistance to a change in pH. If 1 ml of 0.01 N HCl is added to 1 litre of pure distilled water of Neutral pH; the resulting solution would have a pH of about 5.0. Now, on the other hand if the small amount of acid is added [...]
