Composition: 20-80% kaolinite, 10-25% mica and 6-65% quartz
Contains lime: the most important feature of Ballclay soil is that it contains more than 20% of lime (calcium carbonate), which creates unique properties such as the ability to be limed (combined with water) and the formation of hard and stable states.
Stability of the structure: The lime present in Balkali soil makes the soil structure stable and pressure resistant.
