Gatton Research Station, irrigated vegetables, Lockyer Valley
Description– very fertile ‘black earth’ or Vertisol, a dark self-mulching medium to heavy clay soil over heavy clay subsoil with an A1 horizon that is 20 – 25 cm deep and has pH values between 7.0 and 7.8.
Location– flat alluvial plain of the Lockyer Creek at Gatton Research Station
Values for this soil:
– Commercial farming- intensive vegetable production (2 – 3 crops / year)
– Farm research– currently comparing the use of raw and composted animal manures for their contribution to plant nutrition, to determine how mineral fertiliser use can be reduced.
Challenges for this soil to produce vegetables – and their managements:
– Soils crack when dry in sub-tropical climate with moderate rainfall (770 mm pa)- irrigate to keep moist
– Very sticky when wet – irrigating has to be carefully monitored and surface mounded into raised beds
– Nutrients need replenishing for intensive cropping- added animal or mineral fertilizers and crop rotations
