Description
Summary:In recent decades, interest has been generated in integrating agro-industrial and harvest residues into agricultural production in intensive production systems, to reduce environmental impact and production costs. Therefore, the objective of this research was to chemically and physically characterize some locally available agro-industrial and vegetable residues to know their potential use as components of agricultural substrates. Chemical and physical properties of organic materials were characterized: pH and EC, granulometry, average particle diameter, bulk density (Bd), total porosity (Tp), aeration porosity (Ap), water retention porosity (Wp), and moisture retention curves were determined. The pH of the analyzed materials ranged from 5.1 to 10.44, the CE was lower than 2 dSm-1 except for the water lily and banana rachis fiber. The granulometry of the materials had more than 25 % of particles smaller than 0,85 mm; however, the teak shavings and the husk of the oil palm fruit had a Pd with 5.67 mm and 3.21 mm, respectively, which increased their aeration capacity. Pine sawdust and cocoa fruit husk had values higher than the control in Bd, Tp, Ap, Wp and total available water. In conclusion, the materials have different aeration and moisture retention characteristics, and they can be combined in different proportions according to their physical and hydrophysical characteristics and generate a balance in the water-air relationship.

Por ello, el objetivo de esta investigacion fue caracterizar quimica y fisicamente algunos residuos agroindustriales y de vegetales disponibles localmente en el estado de Tabasco Mexico, para conocer su uso potencial como componentes de sustratos agricolas. Se caracterizaron propiedades quimicas y fisicas de materiales organicos: pH y CE, granulometria, diametro medio de particula (Dm), densidad aparente (Da), porosidad total (Pt), capacidad de aireacion (CA) y porosidad de retencion de agua (Pra), y se determinaron las curvas de retencion de humedad. El pH de los materiales analizados oscilo desde 5.1 hasta 10,44, la CE fue menor a 2 dSm-1 excepto para el lirio acuatico y la fibra del raquis de
