What is the optimum pH level for most crops?

The optimum pH level for most crops falls in the range of 6.0 to 7.0 because this range provides an ideal environment for nutrient availability and microbial activity in the soil. In slightly acidic soils (around 6.0), essential nutrients such as nitrogen, phosphorus, and potassium are most accessible to plants. As soil pH approaches neutral (around 7.0), the chemical processes that deliver nutrients are optimized, and beneficial soil microorganisms can thrive, further enhancing plant growth.

Additionally, a pH level within this range reduces the risk of certain soil-related issues, such as metal toxicity or nutrient lockout, which can occur when the pH is too low or too high. This balance supports robust crop yield and health, making 6.0 to 7.0 the best target for agricultural practices.
