{{main|Soil classification}}

One of the first soil classification systems was developed by Russian scientist [[Vasily Dokuchaev]] around 1880.<ref>{{cite web |url=https://fr.scribd.com/doc/206859253/Russian-Chernozem |title=Russian Chernozem |last=Dokuchaev |first=Vasily Vasilyevich |publisher=Israel Program for Scientific Translations |location=Jerusalem, Israel |year=1967 |access-date=18 May 2025 }}</ref> It was modified a number of times by American and European researchers and was developed into the system commonly used until the 1960s. It was based on the idea that soils have a particular morphology based on the materials and factors that form them. In the 1960s, a different classification system began to emerge which focused on [[soil morphology]] instead of parental materials and soil-forming factors. Since then, it has undergone further modifications.
