Abstract
Sorghum plants were grown in lucite-coated cardboard cartons containing a 4-cm layer of sandy loam soil, a 3-cm layer containing variable proportions of clay, silt and sand, a 6-cm layer of sandy loam and a 1- cm layer of sawdust. Germination and emergence were delayed in the finer aggregates. Root length was significantly higher in the coarser aggregates (2-6 mm). In the finer aggregates, most roots grew in interpedal regions, but in the coarser aggregates roots were also found in the intrapedal regions. An increase in the clay and, to a lesser extent, the silt content of the central layer reduced root growth. Max. root growth and penetration occurred in the mixture containing about 50% sand
