Phosphorus is generally most available to plants in soil with a pH between 5.5 and 7.0. Soil pH below 5.5 can result in aluminum and manganese toxicity, which can inhibit phosphorus uptake. Soil pH above 7.0 can result in the formation of insoluble compounds, making phosphorus less available to plants.
