At what soil pH range is phosphorus generally most available for plant uptake?

✅Explanation:
Phosphorus is generally most available to plants in soils with a pH range of 6.5 to 7.5. This slightly acidic to neutral pH range allows phosphorus to remain in soluble forms that plants can easily absorb, such as phosphate ions (H₂PO₄⁻ or HPO₄²⁻). At this pH, the phosphorus is not bound to other soil particles like iron or aluminum (in acidic soils) or calcium (in alkaline soils), making it more readily available for uptake.
