James Rebanks described the importance of observation in farming. Observation informs our decisions about how we manage our farms. For thousands of years farmers have been relying on empirical knowledge passed down through generations, helping them to recognise patterns in the weather, cycles on the land and rhythms within nature. But what can you do when you don’t have that mulit-generational connection with your land?
Today we are armed with a vast array of tools to allow us to make evidence based decision making for our farming enterprises. These tools are usually expensive, difficult to use, or unable to be tailored for specific applications. In my quest to learn more about caring for the soil on the Rock Farm, I recently attended a winter update session hosted by the NSW Local Land Services. One of the sessions was on a web based tool that has enormous potential to help me make better decisions about our farm management.
The tool is Farming Forecaster. This tool has been available in our area for a couple of years, but is rapidly expanding throughout New South Wales and Tasmania. Matt and Phil from the video below attended our session and took us through the tool, how it works, and how we can use it to make better decisions. One of the best aspects of the Local Land Service’s workshops is the calibre of people they have at the sessions, and to hear Matt and Phil explain the tool was a real privelige.
The tool uses real-time soil moisture probes in our district to predict pasture growth. Water in the soil is the largest determinator of pasture growth in our area, followed by fertility. The Farming Forecaster assumes you have appropriate fertility and uses the soil moiture profile to determine pasture growth based on either:
- 30 years of historical data
- Bureau of Meteorology ACCESS S long range forecast data
With accurate pasture growth data, based on 30 years of observed weather, and knowing exactly how much area is available to graze (using free GIS software QGIS) I am able to calculate with reasonable confidence how much feed will be available to my cattle for the next three months.
This information, coupled with data on the amount of feed I can expect my cattle to eat (based on tables from the Local Land Services Soil Fertility and Decision Making Workshop) allows me to make decisions on my stocking rate.
With rainfall and soil types varying across the region, it is important to look at several sites around your farm. You can do this by clicking on the ‘View Network‘ button. There are some great videos that explain the data also available. Additional information on the site can be found here: https://farmingforecaster.com.au/MemberUpdates.
From using Farming Forecaster, I am now able to confidently say that we have an appropriate stocking rate for this season – well at least for now. It is worth regularly reviewing the site as it is updated weekly. For a punter like me, who has so much to learn about animal husbandry, pasture growth and stocking rates, it really helps me to access knowledge that took generations to acquire.
Of course the ones who benefit most from it are oblivious to it – but that is ok. They’re beautiful – and now I know they should be well fed throughout the next couple of months :).
