A comparative study was carried out on chemical, physical and mineralogical characteristics of dusky red latosols originated from the weathering of alcaline (LRe) and basic eruptive rocks (LRd), of the Jaboticabal country Brazil The results showed that the LRe presented a younger development stage than LRd, while this soil showed a tendency to maturity. This trend was corraborated through the lower clay and total Fe2O3, contents and higher base saturation contents, Si2O/Al2O3 molecular ratio (Ki) and clay f ration CEC presented by LRe. It can be concluded that the occurrence of eutrophic dusky red latosols hi the UNESP-Jaboticabal campus may be due to the influence of alcaline rocks.Downloads
