Amended TK soils had significantly smaller (P b 0.05) bulk densities
(0.93, 0.94, and 0.91 g cm−3 for the fresh CS, CS-350 and CS-550
amended soils) than the control (1.01 g cm−3) (Fig. 4). Bulk densities
of the EG soil treatments were not significantly different (P b 0.05)
and values were always below 0.8 g cm−3, as expected for an Andisol
