【 摘 要 】
Physical and chemical characterizations were done for five materials [soil, sand, peat SCv, carbonized rice husk (CRH) and decomposed acacia (Acacia mearnsii) bark after tannin extraction (DAB)] and some of their mixtures [soil + sand (1:1), soil + sand + CRH (1:1:1), soil + sand + DAB (1:1:1), peat + CRH (2:1), peat + DAB (2:1)], trying to identify which of them could be used as growing substrates for potted fruit and flower plant crops. The following properties were analyzed: water pH, salinity, cation extange capacity (CEC), organic carbon levels, dry density, total porosity, air space, available water, remaining water and particles distribution. The growing media "peat SCv + DAB" showed upper chemical and physical properties for the horticultural purposes defined.
