The ideal soil pH range for optimal nutrient availability in mineral soils is generally considered to be between 6.0 and 7.0. At this pH range, essential nutrients such as nitrogen, phosphorus, potassium, and various micronutrients are most accessible to plants. The chemical reactions that govern nutrient solubility and availability are influenced by pH; at a neutral pH around 6.5 to 7.0, many nutrients are readily available while toxic elements like aluminum are less soluble, reducing their potential harm to plants.

Maintaining this pH range also supports beneficial microbial activity in the soil, which is vital for breaking down organic matter and facilitating nutrient uptake by plants. In contrast, soil pH values outside this range, either too low or too high, can lead to nutrient deficiencies or toxicities that can adversely affect plant health and growth.
