A soil pH of 10 indicates which soil condition?

Explanation:
A soil pH of 10 indicates the soil is strongly alkaline. The pH scale shows acidity below 7, neutrality around 7, and basic/alkaline conditions above 7; a value of 10 is well into the alkaline range. In alkaline soils, hydrogen ion activity is low and basic minerals (like carbonates) predominate, which changes nutrient availability. It’s not acidity or neutral, and salinity refers to salt content (conductivity) rather than pH, so those ideas don’t match what a pH of 10 describes.
