Abstract
Marginal lands have received wide
attention for their potential role in food production and environmental
rehabilitation. Hence, this study aimed to evaluate the ecological qualities of
the two degraded upland soils in Inopacan, Leyte and Sta. Rita, Samar. Site
properties were evaluated quantitatively in terms of rootability, availability
of air, water and nutrients, as well as nutrient reserves. Results showed that
both soils have shallow to moderate rooting deep, poor to moderate rootability,
low to high air capacity and moderate to high available water supply to the
plants. Moreover, both soils obtained higher nutrient reserves for cation
exchange and the limiting factor for plant nutrition is given by the very low amount
of nitrogen supply.
