The process of changing a substance to make it more alkaline, which means it has a higher pH level and is less acidic.
The alkalinization of the soil improved its fertility.
Alkalinization is formed from "alkali" (from Arabic "al-qaly", meaning the ashes of saltwort plants) and "-ization" (meaning the process of making or becoming). The word refers to the process of making something alkaline or increasing its alkalinity.
Think of the process of turning something into an 'alkali' — that's what 'alkalinization' means.
