TAVARES CORREA, Carlos y SABOGAL DE ALEGRIA, Ana. Estabilización de dunas litorales utilizando Sesuvium portulacastrum L. En el departamento de La Libertad, costa norte del Perú.. Ecol. apl. [online]. 2003, vol.2, n.1, pp.47-50. ISSN 1726-2216.
Preliminary results on the utilisation of verdolaga (Sesuvium portulacastrum L.) on the foredune stabilisation are presented. The study was carried out at Santa Elena (7°28'52''S and 79°33'22''W), northern Peru. Initially, propagation tests were made with terminal, medium and basal stem cuttings in plant pots using the following soil treatments: pure sand, sand/humus and sand/humus/loam. Then, 115 plants with well developed roots were transplanted to a 20 x 5 meters plot near the beach, in three rows separated by rows of 160 rootless terminal cutting stems. In both cases, 75% of the plants were treated with a slow release fertiliser and 25% did not receive any treatment. A porous fence was built for the protection of the young plants from the abrasive action of the sand grains. Forty days after sowing, 138 plants survived and 142 died. Among the survivors, 118 were treated with a slow release fertiliser and 20 were not. In addition, 107 were rootless terminal stakes and only 31 were nursery propagated plants (plant pots). Four months after the beginning of the experiment, a vegetal cover of 60% and an initial dune formation were obtained. Initial conclusions suggest the utilisation of terminal cutting stems treated by slow release fertilisers and the use of porous fence for the prevention of deflation and against wave erosion.
