Physical properties of soil mixes used by nurseries
Soil mixes have been proposed and are being used by nurseries for various reasons. Evaluations of their properties relating to disease control and fertilization have been well documented. The selection of mixes for favorable physical properties is equally important, but methods for routine evaluations of such properties have not been sufficiently explored. The following data show evaluations of physical properties measured with laboratory techniques and, for comparison, similar measurements on mixes as they are used in gallon cans under nursery conditions.
