Information
Runoff, soil loss and crop yield from Pineapples under a range of management practices -Goomboorian
Level 1
Purpose
To identify appropriate land management practices for pineapple farming.
Method
This pineapple study commenced in 1991, with monitoring conducted for 4 consecutive years near Goomboorian, Gympie. Runoff and soil loss were measured for three treatments (bare plot, conventional practice and furrow mulching).
Key findings (brief)
For the period 1991 to 1995 annual average rainfall was 1045 mm, while runoff and sediment loss for each treatment can be viewed in the below table. Annual runoff and soil loss concentrations were sustainably lower in the improved practice (furrow mulching) (150 mm and 3 t/ha, respectively), while the bare research plots recorded the greatest losses (286mm and 216 t/ha).
This brief results summary was used to tune the Howleaky model with minimla tuning and reasonable confidence in model robustness.
