Phosphorus dynamics in conservationist agroecosystem maize-cattle of neotropical savanna ; Dinámica del fósforo en un agroecosistema conservacionista maíz-ganado de sabanas neotropicales

Phosphorus is one of the limiting elements in acid soils, so the incorporation of strategies for its cycling within an agroecosystem is one of the key variables, in order to optimize agricultural production. The dynamics of phosphorus in a maize-livestock agroecosystem were evaluated under the types of forages introduced: Brachiaria dyctioneura (Bd), a grass and Centrosema macrocarpum (Cm), a legume, which in turn served as associated perennial coverages maize grown with direct sowing. The dynamics of this element are contrasted in the savanna of natural vegetation (SN). It determined the avai... Mehr ...
