N-fixing legume tree and erosion control
The flamboyant is a N-fixing legume that can improve soil N status. Leaf and green stem prunings applied to a calcareous soil for 5 years resulted in improvement of 13% in N and higher organic C and mineralization (Isaac et al., 2003).
As a shade tree, Delonix regia is helpful in maintaining soil moisture and reducing soil temperature. Flamboyants have been planted on eroded sites for erosion control, and for soil rehabilitation (Rojas-Sandoval et al., 2013).
