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

✅Explanation:
Phosphorus (P) availability to plants is highly dependent on soil pH. It is most available in the slightly acidic to neutral pH range of 6.5 to 7.5, where phosphate ions (H₂PO₄⁻ and HPO₄²⁻) are most soluble and accessible to plants.

• At pH levels outside this range:
-In acidic soils (pH 7.5), phosphorus reacts with calcium (Ca) to form calcium phosphates, which are also insoluble.

🛑 Additional Information::
-Farmers often adjust soil pH through amendments like lime (to raise pH) or sulfur (to lower pH) to optimize nutrient availability.
-Regular soil testing is essential for managing phosphorus and other nutrient availability effectively.
