Characteristics of red basaltic soil under Pinus kesya and Acacia hybrid plantations in the North T’Nung Lake’s protection forest, Gia Lai province

This study explores the characteristics and properties of red basaltic soil under Pinus kesya and Acacia hybrid plantations in the North T’Nung Lake’s protection forest, Gia Lai province. The study finds that red basaltic soil under the Acacia hybrid plantation has higher values in terms of grain composition, acidity, and nutrient content than red basaltic soil under the Pinus kesya plantation. These results show that plants play a role in changing soil properties. Based on the study’s findings, it can be initially concluded that the red basaltic soil under the Acacia hybrid plantation is better than that under the Pinus kesya plantation.
