Making decisions about your agricultural enterprise is all about managing
risk. Therefore being able to put some probabilities to the question of
how a season will develop will be much less risky if you have at least five years worth
of records to benchmark against in one simple graph.
If the season starts 3
weeks before the historical average date, allowing earlier pasture establishment
before the winter chill,
- How many more animals would I be able to run during the winter and spring?
- Can I opportunistically increase the area of crop on the assumption of a
longer growing season will provide a better than average yield?
- How will having green feed earlier in the season affect the fibre diameter
profiles of my young animals?
- How will that affect the mean fibre diameter targets I have set for that
group to access premiums?
Alternatively if the start of the season is delayed by 3 weeks,
- Do I reduce the area to be cropped on the assumption of lower than average
- How much additional supplementary feed would I need until my pastures were
- By how much would the total pasture production be reduced this year due
to the shorter season?
- How do I plan to conserve forage for next summer and what impact will that
have on the total wool or meat per hectare produced this season?
Benchmarking against previous years
Our database of historical PGR started in 1995. While this does not
compare to the memory banks of most agricultural producers we are closely
working with, it is sufficient to start placing some certainties to the decision
based on this technology.
