The pattern of long-term soil phosphorus decline and increasing biological
phosphorus limitation at Cooloola is consistent with biogeochemical
theory (Walker and Syers, 1976). However, the pre-weathered
nature of the parent sand means that the pattern of soil phosphorus
chemistry differs from that observed along other long-term
chronosequences (Peltzer et al., 2010) and is therefore most similar to
the Mendocino terrace chronosequence in California, USA (Izquierdo
et al., 2013).
