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...

The outcome of the research has been summarised in the book "Managing Frost Risk - A guide for Southern Australian Grains"... The agronomic practices needed to reduce frost risk are summarised in Table 1... As described by Gusta (2007), the process of cold acclimation (where some crops show an increase in freezing tolerance by being exposed to temperatures of less than 8 C) is under genetic control and the genes responsible for the increase in freezing tolerance are regulated by temperature in the field...

Why frost needs a risk-management mindset.. Frost is a low-frequency but high-consequence event aiming for the median latest date is too risky... Information from the GRDC National Frost Initiative on the ranking of frost susceptibility, agronomic methods to change temperature at head height and forecasts of the likelihood of frost have to be incorporated into sound risk management...

Like all Western Australian growers, Paul and Siobhan Hicks are finding they are constantly having to push out the technical boundaries to cope with declining rainfall that is compounded by non-wetting soils and increasing frost events... "We have a two-week window after a frost to decide if we will mow for hay or wait to harvest," Paul says...

A diverse enterprise is paramount to managing the increasing effects of frost on the Hansen family's cropping operation... Farming at Coomandook in South Australia's upper south-east, brothers Andrew and Garry, their wives Joanne and Merrawyn and five employees implement several pre-season and in-season tactics to mitigate the effects of frost as best they can... Andrew says that, over the years, they have become better at identifying frost damage and puts the extent of damage down to the relationship between soil type and topography...

Spread of flowering dates of dry sown crops can be successfully achieved through varietal choice and adjusting sowing order of the wet sown crop according to the flowering prediction of the dry sown crop... The aim of this paper is to discuss possibility of using varietal differences in phenology mechanisms to achieve a desired spread of flowering dates after dry sowing... The data were used to estimate: 1) spread for flowering dates of varieties across germination dates, 2) the range of achievable variation through varieties for given sowing dates...
