Abstract
Experiments were conducted to obtain correlations between physical soil properties and crop yields in order to determine the correct use of soil ameliorants such as barks and plastic foam materials. From the results recommendations are made on desirable thresholds of air and water capacity, porosity and dry matter of soils and substrates used for cucumber, tomato and lettuce.
