A factorial design was used that included four seeding methods by four lime rates ( Table 1 ) arranged in a randomised block with three replicates, and plots were 2.16 m by 15 m.
Calcitic limesand was applied at the indicated rates to all three trials in April 1999. The limesand had a neutralising value of 90% with 99% of the material passing through a 0.6 mm sieve.
Additional limesand was applied only to the FCNT seeding treatment (No. 4) in April 2004 at the same rates as used initially ( Table 1 ).
