Brief description
This collection includes datasets from experiments conducted across multiple sites within the Northern Region. These experiments aim to better understand the effectiveness of different cover cropping strategies on water infiltration and evaporation.Full description
This collection includes datasets from experiments conducted across multiple sites within the Northern Region. These experiments aim to better understand the effectiveness of different cover cropping strategies on water infiltration and evaporation.
More information is available in the linked final technical report for this project.
Nearest towns with focus of individual experiments (further details in linked final Techincal Report):
- Yelarbon (winter cover crops on a short fallow for pivot irrigated back-to-back cotton)
- Bungunya (summer cover crops on a long fallow for dryland wheat after skip-row sorghum)
- Goondiwindi (winter & summer cover crops after chickpea before irrigated cotton & grain; not planted)
- Yagaburne (winter & summer cover crops before wheat)
- Billa Billa (summer cover crop & wheat stubble comparison before wheat)
- Lundavra (wheat stubble loads & heights versus cover crops)
- Croppa Creek (barley cover crops before overhead irrigated cotton; not planted)
- Parkes (short fallow systems with summer cover crops for grain)
- Parkes (long fallow systems with summer cover crops for grain)
- Canowindra (short fallow systems with summer cover crops for grain)
- Canowindra (long fallow systems with summer cover crops for grain)
- Yanco (system study cover crop sequences under flood irrigation for cotton)
- Yanco (Spray-out timing study of winter cover in flood irrigated cotton beds; to match other locations)
Treatments/Factors:
- Combinations of cover-crop variety by Spray out timing. Combinations vary by site.
- control (bare)
Below is an example of the treatments from the Yagaburne Qld site, prior to planting wheat.
