A melon demonstration site in Ayr, Far North Queensland
A new SWICP demonstration site at the Department of Primary Industries’ Ayr Research Facility in northern Queensland is exploring how cover crops and biostimulants can work together to enhance soil health, resilience, and productivity in melon production systems.
Fallow periods between crops can lead to declines in soil health. This trial is investigating whether integrating cover crops, alone or in combination with biostimulants, can help to restore soil function while improving crop yield and quality.
Running through to the end of 2026, the study will test various combinations of cover crops and a Bacillus-based biostimulant to identify practical approaches that:
• Build soil structure and fertility
• Reduce erosion and weed pressure
