Why is soil pH testing useful in agriculture?

Answer and explanation

Correct answer: It helps determine the acidity or basicity of soil

Soil pH indicates whether soil is acidic, neutral, or basic. Testing it helps farmers select suitable crops and decide whether an amendment is needed, such as lime for excessive acidity or suitable organic matter and management for other conditions. Therefore, option A is correct. Testing does not transform soil, supply water, or change plants into metals, as the distractors claim.
