Climate and mineral content are the ultimate causes of soil pH. Soils in hot and dry areas tend to be alkaline because with little rainfall, there is little plant growth and with little plant growth, there is little acid producing organic material in the soil. Also, little rainfall allows for the accumulation of alkaline salts. Soils in areas with plentiful rainfall tend to be acidic for the opposite reasons.
