Alkali, or alkaline, soils are clay soils with high pH ( 9), a poor soil structure and a low infiltration capacity. Often they have a hard calcareous layer at 0.5 to 1 meter. depth (in India this layer is called 'kankar'). Alkali soils owe their unfavorable physico-chemical properties mainly to the dominating presence of sodium carbonate which causes the soil to swell. They derive their name from the alkali metal group of elements to which the sodium belongs and that can induce basicity. Sometimes these soils are also referred to as (alkaline) sodic soils. Alkaline soils are basic, but not all basic soils are alkaline, see: "difference between alkali and base"
