Soil pH and Nutrient Availability
Soil pH is the most important factor which governs the availability of nutrients in soil. All the nutrients are absorbed by plants in their ionic form, since the solubility of these ions is pH dependent, the availability of nutrients in soil is also pH dependent. Fig.3.1 gives an idea of the pH range for availability of different nutrients in soils. The pH range of 6.0 to 7.5 appears to be optimum for the availability of most of the nutrient elements.
