The laboratory methods of soil science can be adapted for the evaluation of physical and chemical properties of a growing medium, but it is unique that horticultural plants are grown on organic or soilless substrates usually and in containers. The paper reviewed that major physical properties used to describe a container medium or medium component are : bulk density, air- filled porosity, particle size distribution, and water release characteristics. On the other hand, there are four important chemical properties to be considered: pH, soluble salts, soluble nutrients and total nutrients. Those would be useful for horticulture crop growers and researchers.
