Multiples investigaciones recomiendan su siembra en sistemas agroforestales debido a su potencial economico e industrial, basado en la extraccion y comercializacion de cera y sus servicios ambientales para la conservacion de suelos, control de la erosion y procesos de restauracion para bosques secundarios y riberas hidricas, puesto que posee raices profundas y abundantes las cuales, ademas, albergan en sus nodulos el actinomiceto frankia, que tiene la capacidad de fijar nitrogeno(N) (Mahecha, 2004; Luna, 2006).

There are other plants that form symbiotic relationships with bacteria to fix nitrogen--such as alder trees, which form a symbiotic relationship with Frankia bacteria--but legumes are the only food crop to do so.
Black alder could be considered to be a "biological fertilizer", which improves soil nitrogen status, fixing N2 in symbiosis with Frankia in its root nodules, and increases phosphorus availability in soil by the activity of its roots and associated microbial communities [13, 14].
