What type of soil has a pH greater than 7.0?

Soil with a pH greater than 7.0 is classified as alkaline soil. This type of soil has more basic components, which can result from various factors such as high calcium carbonate content, low levels of organic matter, or specific environmental conditions. Alkaline soils can influence nutrient availability and plant growth, as certain nutrients may become less available to plants at elevated pH levels.

In contrast, neutral soil typically has a pH around 7.0 and does not have the basic or acidic characteristics associated with soils outside this range. Acidic soil has a pH below 7.0, indicating a higher concentration of hydrogen ions, which can lead to different nutrient dynamics. Loamy soil is a balanced mixture of sand, silt, and clay but can have varying pH levels; it is not specifically categorized by pH characteristics like alkaline or acidic soils. Thus, the identification of alkaline soil as having a pH greater than 7.0 is essential in understanding soil chemistry and plant nutrition.
