Day
two (first day of the tour proper) will feature the soils and crops of the
lower Burdekin floodplain south of Townsville.
This is Queensland's
premier irrigation area with more than 80,000 ha of irrigated land; and the day
will begin with an overview of the region and the irrigation scheme. Sugar cane
dominates, but there is also a range of other horticultural and vegetable
crops.
Natural
resource management issues include water quality (sediments, nutrients, salts,
agrochemicals), salinity (dryland, irrigated, saltwater intrusion) and land degradation
(erosion, soil acidity, salinisation). You
will examine contrasting soil types and production systems on three different
farms. Soil management issues include
sodicity, fertility decline rising groundwater and conversely excessive
drainage at certain sites.
Return to Townsville for the night.
