What is the ideal pH range for most crops?

The ideal pH range for most crops is typically between 6.0 to 7.0. This range is considered optimal for nutrient availability and microbial activity in the soil. At a pH of around 6.5, essential nutrients such as nitrogen, phosphorus, potassium, and various micronutrients are readily available to plants.

Soils that are too acidic (like those in the 4.0 to 5.0 range) can lead to nutrient deficiencies because certain nutrients become less available, whereas alkaline soils (7.5 to 8.5) can also result in nutrient imbalances, particularly affecting the availability of iron, manganese, and zinc. Therefore, maintaining soil pH within the 6.0 to 7.0 range helps ensure that crops can access the nutrients they need for optimal growth and productivity.
