Them's remarkable yields over that much acreage--we'll get some like that in good years but a 40 bu/A average would be pretty remarkable.


Several factors, first is this year the rainfall was above average and more importantly, fell just at the right time and in the right quantities. Second is the wheat varieties keep getting better and better. The plant breeders are producing plants with yields that were not thought possible and seem somehow to continue to do that.
The inputs are carefully controlled as well. Soil sampling is a necessary part. Everything, including spraying and fertilising is custom applied through GPS linked computer controlled equipment. It all gets downloaded to a database and forms the basis for the following year as well.
An example is ryegrass control. At harvest, the GPS records the exact path the combine takes. When the first rains occur prior to planting, the emerging weeds are sprayed. Each nozzle on the boom spray is linked to a computer that has the information from harvest of the combine path. It applies the heaviest dose on the area where the combine left the windrow containing most weed seeds in the prior harvest. Same principal applies to seeding, - fertiliser rates are automatically adjusted according to last seasons yields and soil analysis via GPS.
The next combine that is bought , which will probably need to be in 3 years time, will also have full automatic control via GPS. No need for operator input at all. It will steer itself, continually adjust threshing settings and ground speed as well as controlling the cutting height of the front. We'll probably see 60ft fronts by that stage. The operator will simply sit there and monitor what is happening. I can see the day when even that will occur remotely.

How things change. It's all moved so quickly. (My last combine, - we call them headers, - when I was contract harvesting, had a 22ft open front. 18ft was considered by most at that time as being the maximum that an operator could handle safely. That was less than 20 years ago!

I'm off to make some sawdust.
