Abstract
The study was conducted to determine appropriate soil properties for Adenosma bracteosum
Bonati via the coupling between the plant growth and soil conditions in Lo Go –
Xa Mat National Park, Tay Ninh province, Vietnam. Experimental plots were installed
in three grasslands based on the presence of A. bracteosum. The plant heights and
number of individuals were measured monthly during the growing season for growth
evaluation and soil samples were collected to determine the discrepancies in soil
physicochemical properties between the chosen sites.
The results implied that A. bracteosum could not grow in soils with humidity < 18.4%,
dry bulk density > 1.5 g.cm-3, pH < 4.9, fine grain proportion > 54.2%, total nitrogen
content < 0.1% and available phosphate content < 0.0113 mg.g-1. The soil conditions
in the habitats of A. bracteosum were probably just sufficient to maintain the appearance
but not optimal for the plant growth and development.
