Decomposition of bovine esterco and Gliricide sepium biomass in a Regolytic Neo...
Pérez-Marin, Aldrin Martin; Sarmento, Maria Iza de Arruda; Vendruscolo, JhonyThe use of organic wastes such as manure, crop residues and green manuring to improve soil fertility and agricultural productivity is one of the strategies used by family farmers in the Brazilian semi-arid. In this context, the objective of this study was to evaluate the dynamics of N, P and K after the incorporation of manure or biomass of gliricídia (Gliricídia sepium). The work was conducted within an area w...
Productivity of forage nopal in alley cropping of gliricídia under organic fert...
Santos, Ailton Francisco dos; Pérez-Marin, Aldrin Martin; Sarmento, Maria Iza de ArrudaIn the Semi-Arid region of Brazil, livestock farming is one of the main economic activities. However, the production of biomass by fodder is unstable over time due to irregular rainfall, causing an imbalance between the supply and demand of fodder to feed the herds. One of the strategies to circumvent this problem concerns the cultivation of forage palm in a consortium with leguminous tree species. The present ...
Chemical attributes of soil in agroforestry system of gliricidia intercropped w...
Sarmento, Maria Iza de Arruda; Pereira Junior, Ednaldo Barbosa; Pérez-Marin, Aldrin Martin; Medeiros, Aline Carla de; Maracajá, Patricio BorgesIn this study, we aimed to assess the chemical attributes of a soil fertilized with organic matter, in an agroforestry system. The experiment was carried out at the Miguel Arraes agricultural experiment station of the National Semiarid Institute (INSA), located in Campina Grande, Paraíba, Brazil. Experimental design consisted of a randomized block with four replications. We applied four treatments of organic fe...
