spring frost

Now is the time to implement frost strategies.. Grain growers can best minimise crop losses from spring frosts by planning and implementing strategies prior to or at seeding time... "High stubble loads (greater than 2.5 tonnes per hectare) appear to increase frost damage by reducing the amount of heat radiated from the soil at night, leading to lower canopy temperatures and greater frost severity, duration and damage," he said...

Later in the season, there are fewer in-crop strategies to reduce frost risk... Being conservative with nitrogen in frost-prone paddocks can reduce risk and financial exposure, as crops with larger canopies suffer more frost damage... "Growers should be vigilant and inspect crops regularly following a suspected frost event and be aware of what potential salvage measures (such as cutting hay or brown manuring) are at hand for their enterprise if a crop is affected," Mr Knell says...

Grain growers throughout the southern cropping region are advised to expect a heightened risk of frost this season due to the developing El Ni o climate event... Dr Hayman, who is involved in frost research projects being funded by the Grains Research and Development Corporation (GRDC) through its National Frost Initiative, said while the risk of frost was expected to be increased this year, the exact timing and frequency of frost events could not be predicted... The GRDC is continuing its long-term commitment to funding frost-related research, with its recently launched five year National Frost Initiative focused on identifying and delivering practical genetic, management and environmental solutions to assist growers to manage the impact of frost...

" Pulse germplasm enhancement - vegetative and reproductive frost tolerance in pulse crops DAS00066 Start Date: 01/01/2006.. The final year of this project was used to confirm earlier findings and develop the concept of field-based screening for phase II of the germplasm enhancement (GE) program linked to Pulse Breeding Australia (PBA)... The expected outcome of this project was the development of frost tolerant germplasm in field peas, chickpeas and lentils which could be used to develop new varieties that would ultimately sustain and expand the pulse crop production area and provide increased yield and improved grain quality...

Crop grazing can reduce early sowing frost risk.. Grain growers in frost prone areas should not be afraid of taking the opportunity to sow wheat early, if moisture is available, as the risk of damage to crops can be reduced using crop grazing to delay flowering... "At the Newdegate trial site, we found that early simulated grazing of crops for 10 days delayed flowering by four days; 20 days of grazing resulted in a 10 day delay, and grazing for 30 days extended flowering by 13 days," Mr Curtin said...

"High stubble loads (greater than 2.5 tonnes per hectare) appear to increase frost damage by reducing the amount of heat radiated from the soil at night, leading to lower canopy temperatures and greater frost severity, duration and damage," he said... Mr Knell said growers needed to ensure that all wheat crops in frost prone areas did not flower at the same time... Mr Knell said growers could also consider longer-term measures including claying and cultivation, although cultivation was not scientifically proven to reduce frost damage and claying was expensive...

Loss of wheat production due to frost damage is not common in Victoria... A frost in the Wimmera on the morning of 28 October 1998 resulted in loss of yield of 60% in wheat and barley crops, 90% in field peas, 85% in chick peas, 60% in lentils and 40% in canola... The pictures show wheat damaged by frost at different stages of growth...
