In forming lime recommendations, which soil parameter is essential to determine how much lime to apply?

Explanation:
Knowing the soil pH is essential because lime is used to raise acidity to a level where nutrients are most available, and the amount of lime needed is driven by how far the current pH is from the desired target. The soil’s buffering capacity, which is influenced by texture and organic matter, determines how much lime is required to achieve that change, but you can’t set the correct rate without starting from the current pH. Color has no bearing on lime requirements.
