Information
Nitrogen loss in sub-surface drainage from bananas in tropical north Queensland
Level 1 General description
Purpose
The study monitored nutrient infiltration under a commercial banana plantation.
Methods (brief)
Lysimeters were installed to collect leachate from below the root zone. The monitoring period included 2 dry and a single wet season.
