Question

The ph of a soil a' is 7.5 while that of soil b' is 4.5 which of the two soils should be treated with powdered chalk/ powdered egg shells to adjust its ph and why?

Answer 1

Given :

Soil A with pH value= 7.5

Soil B with pH value= 4.5

Here Soil A is basic in nature and soil B is acidic in nature.

Thus, soil A should be used to treat with chalk powder which is basic in nature to neutralize and to make the soil more fertile.
