Annual trial results and personal profiles of the innovative leaders in the Queensland sugar industry, backed up by the technical data of previous case studies.
The aim of telemetry is to use sensors to detect changes in soil moisture and in turn automatically inform the grower when adequate soil moisture is achieved or when irrigation must be applied.
To reduce the amount of Nitrogen and Phosphorus applied to varieties that have high nitrogen use efficiency without suffering a yield or sugar reduction.
To reduce the amount of Nitrogen and Phosphorus applied to varieties that have high nitrogen use efficiency without suffering a yield or sugar reduction.
To use crop sensors to spatially locate variations in soybean yield and to create nitrogen application maps to match the variability without having a negative impact on sugarcane yield.
To compare cane yields and soil analysis from locations where liquid fertiliser has been applied sub-surface compared to liquid fertiliser that has been applied to the surface.
By having cover crops during the fallow period we are hoping to add organic sources of nutrients to the soil profile which in turn will help produced a good plant cane crop which will follow through for a full crop cycle.
To determine whether reducing fertiliser rates on older ratoons (3R onwards) will maintain productivity, reduce grower costs and reduce the risk of applied nitrogen leaving farms.
