Variable Rate Drilling Made Easy by Omnia – The Scottish Farmer – Lewis McKerrow, George Robson

Making the transition to variable rate drilling smoother than ever before... ...

Ease of connectivity has made the transition to variable rate drilling smoother than ever before for Robert Sullivan, of GSC Grays and farm manager of Raby Estates.

He had been looking at how best to introduce variable rate applications across the two farms that make up the estate in Durham and Shropshire.

“We had already started using the Omnia system on our Shropshire farm and were impressed with it. We had confidence in the system, so it made sense for us to look at how we might be able to make it work in Durham.

“On a more strategic basis, it would also allow us to record and share data across two farms and make well-informed management decisions accordingly. One of the challenges was the logistics of our Durham farm – the 2800 acres of combinable arable cropping is spread out and has 16 miles of road between the most eastern and westerly fields.


“Hutchinsons agronomist, George Robson, introduced us to the Omnia Precision expert, Lewis McKerrow, who talked us through the Connect app and how easy it would be to generate and share variable rate plans across the machines on the farm – irrespective of geography! Lewis made the initial set up very straightforward and, importantly in a language, that a farmer like myself could understand and interpret!”, he said.

“The first step was to bring across data from our earlier soil sampling service into Omnia to which we also added yield maps. Being able to use historical data was a real advantage, saving both time and money.

“Once all the data was inputted and variable rate plans developed all we had to do was plug in the iPad. Using Connect, the plans were downloaded straight onto an iPad in the tractor cab – and then it was all systems go.”

It has been simple to use, to, he said. “We don’t have to worry about downloading the plans onto a memory stick and then doing the same again in the cab. The whole process is very intuitive, logical and very simple to use.”

Initially, he had planned to concentrate on variable rate P and K applications, but has also used it to produce variable rate drilling plans.

“We have now drilled variably for two years – and in fact this year all of our combinable crops will be variably drilled.”

“The benefits of this approach are without doubt more consistent crops, this was particularly noticeable in last year’s spring barley. We started off on this journey thinking our main savings and benefits would be in variable fertilisers, but we have actually seen more value from the drilling in terms of yield benefits in the end.”
