摘要:
Variations in the plant growth media were achieved by combining kaolinite clay (<lμm esd.), silt (2–50μm esd.) and sand (100–250μm esd.) in various ratios. Peds of different sizes were separated from an Okolona clay soil and used as a growth media. A layer (3 cm thickness) of the sand, silt or clay and their combinations were intercalated between sandy loam soil material in a lucite coated cardboard carton. After 21 days the plants were harvested and analyzed for a number of growth parameters and related to the physical and micromorphology of the central control layer.
