Question

How can you raise the pH of acidic soil?

Answer 1

By the use of agricultural lime.

Explanation:

Agricultural lime (`CaCO_3" or " MgCO_3`) is regularly added to soils to adjust `pH`. Some plants and vegetables prefer an acidic soil (cf. tomatoes), whereas other plants prefer limy (alkaline) soils, e.g. beans, carrots. Note that when we talk of acid/alkaline soils, the `pH` range would not fall too far from `7`.
