    Nitrogen content in soils of silvopastoril systems of Prosopis spp. from the Paraguayan Central Chaco by Maura Isabel Díaz Lezcano, Cynthia Carolina Gamarra Lezcano, Mirtha Lucia Vera de Ortiz, Andrea Victoria Santa Cruz Estigarribia

    Published 2021-07-01
    “…Eight plots of 1.0 ha each were established, in which all the carob trees were measured for the estimation of forest biomass, from samples of pastures under and outside the canopy of the trees where, in addition, soil samples were extracted at depths of 0-10 cm and 10-30 cm to determine the nitrogen content, estimated from soil organic matter. In the forest inventories, individuals of the Fabaceae family were identified, followed by the Apocynaceae, Bignonaceae, Capparaceae, Rhamnaceae, Sapotaceae and Zhygophyllacea families, with the Prosopis genus (carob) being the most abundant, associated with pastures of Megathyrsus maximus, Digitaria decumbens and Cenchrus ciliaris species. …”
