A picture worth more than a thousand words
Russell Lethbridge & family
- 3 Properties in Far North Queensland
- ~ 320,000 ha
- 14,000 head of Beef Cattle
For Far North Queensland cattleman Russell Lethbridge and his family, FarmMap4D provides the pictures that allow for grazing management that has really made a difference, and became an easy to use ‘game changer’.
Good grazing management is crucial. From stocking rates to soil nutrients, grazing management allows maximisation of available land and sustainable pastures.
“The flow-on effect of getting your grazing and nutrition right is huge in production. Get it wrong and you’ll watch it go the other way – all of a sudden you don’t have the utilisation that you should be having.”
Maximise their use of available land, and pinpoint areas that cattle do not use.
“It seems very simplistic but it’s a big part of grazing management to know how big an area you’re dealing with, because the size of the paddock is one thing but the grazeable area is different again.”
Russell using the Grazing Circles module of FarmMap4D.
“The first thing we do when we’re developing a new property or looking to site a fence line or pipeline or compare ground cover over time is jump on the map, and you can see it all in front of you,” Russell says.
“It used to take weeks on a motorbike with a GPS in your hand to work out the grazeable areas, and in the rougher terrain you couldn’t actually get everywhere. Now you can map all your infrastructure in the office in a matter of hours and ground-truth it on a motorbike or from a helicopter where possible.”
Russell Lethbridge remembers what a revelation it was to be able to measure exactly how big the paddocks were on 22,300 hectare ‘Werrington’ at Einasleigh, when the Lethbridges were first involved in developing the precursor to FarmMap4D in the early 2000s.
“The first thing we do when we’re developing a new property or looking to site a fenceline or pipeline or compare ground cover over time is jump on the map, and you can see it all in front of you,” Russell says.
“At Amber we measured grazeable areas and put circles around existing waters to see what we could actually run. We had an idea of where we needed to focus our efforts to get the biggest bang for buck in increasing carrying capacity when we bought it, but FarmMap4D makes that immediate – ‘If we do this and this, there’s another 1000 head we can run’,” says Russell.
Clarity on infrastructure
“The same applies to fencing and watering. We’ve already started closing some paddocks off and measuring fence lines. Measurement on these big places can be a long way out, and the accuracy of FarmMap4D is critical when we’re outlaying money.”
Ground and tree cover can be measured and compared over time through FarmMap4D, and it’s even possible to compare the time lapse data with a site 50km outside the property boundary.
“All our country’s undulating so we need to know at the onset what to expect when laying pipe – ‘Werrington’ is 2700m above sea level and quite hilly, ‘Rainmore’ is 100 per cent dams, ‘Amber’ is different with 40km of running water from the Lynd River, and we’ve just sunk three bores there,” says Russell.
“For example, if you want to put in a 6km poly pipeline, FarmMap4D will give you the contours it’ll follow and calculate the head – the size of the pump and pipe you need – and you can send it to a pipe supplier or whoever’s in charge of hydrology on the project and it’ll be right every time.”
Smart stocking rates
“We make sure the young breeders have some of the best nutrition on the place and we match the stocking rate to carrying capacity by removing sub-fertile animals when we’re doing our grass budget,” says Russell.
While ‘Werrington’ – now managed by Russell and Donna’s son Clayton – and ‘Amber’ are running breeder herds, ‘Rainmore’, managed by Vicki and Andrew Revett, is the family’s growing and fattening block for male weaners and cull females, destined for the domestic feeder trade or 100-day Japox in Darling Downs feedlots.
A Game Changer
“If we fail to use and embrace innovation there is no way we’ll keep pace with our competitors in producing beef. And once you have a play with FarmMap4D, that’s when you’ll think, what CAN’T it do?”
