Question

You are given two soil samples A and B. Sample A has pH 4 while sample B has pH 10. What should be added to each of the soil samples to make them suitable for growing plants ?

Answer 1

Answer:

However, if soil Mg tests excessive and pH needs to be raised, use high calcium (calcitic) limestone. Conversely, use dolomitic limestone (calcium magnesium carbonate) for raising pH if soil Mg tests low or deficient.
