abstract:
A morphometric structure analysis was made of 8 horticultural substrates applied for plant cultivation in containers. The basic parameters applied in computer image analysis were investigated, i.e. macroporosity (relative area of cross-section of pores with sizes above 43 μm), number and mean area of pores cross-sections, length of limit line between pore cross-sections and structural elements of solid phase, mean intercept length of pore cross-sections. Value of macroporosity allows the assessment of the substrate ability for retention of easily available water for plants.
