The focus was on being able to rip and inject lime to depth, to attempt to alleviate the acidity and aluminium toxicity that resulted from the low pH.

Initial treatments 2000 Treatment 1 Ripping at 10-15 cm Treatment 2 Ripping at 10-15 cm and again at 15-20 cm Treatment 3 Ripping at 10-15 cm and blowing lime in at depth at 1 t/ha Treatment 4 Ripping at 10-15 cm and again at 15-20 cm and blowing lime in at depth at 1 t/ha Treatment 5 Control Subsequent treatments 2004 In 2004, each initial plot (dimensions 12m wide by 100m long) was split in two. One half (6m wide) was top-dressed with 2t/ha, the other half did n |
