I have started to try and vari rate AN a bit by eye only but anecdotally I am evening out crops which is helpful. I'm not interested in GPS/ sensor vari rate seed/ AN yet but I would like to alter seed rate on the move. Anybody ever modified an accord type mechanism to do this? Surely fairly simple if had correct sort of electric motor to wind barrel in and out? Its knowing the position that perhaps makes it a bit tricky.
Noted. I think it could be done. Half a turn shouldn't make much difference.I hope you've got plenty of spare seed - winding the metering barrel in and out has the potential to alter the rate by a massive amount. You'd be better off replacing the metering drive drive with an electric motor, radar/GPS and a new control box IMHO.
We were on a farm walk in october in wiltshire on some very stoney light soils. Very large fields in comparison to our own and on some very rolling countryside. We were shown a 120 acre field that had used variable rate seeding as a trial which if successful they would run out over the entire acreage which was substantial. The manager who hosted the walk was not happy as the variation in the seed rate was 80kg/ha up to 200kg/ha which is normal farm practise. It was varied off some scanning machine and then a seed map created. The farm let the system do its thing and did not override anything so they could see warts and all. Basically where the rates dropped to below 100kg/ha the slugs ate the wheat. Where the rates were at 200kg/ha the slugs had attacked it but the crop was there and would go to harvest. They obviously applied pellets as per normal but the managers conclusion was if you go to variable seed rates then your slug pellet use increases so they were not taking the system any further. It was a disaster really.
Showing my ignorance ,please can you explain when time allows,electroconductivity scanning and ground truthing .
On a "VERY" stony patch of soil, would it mean one would increase seed rate to make up for seed that was left on the surface due to coulter bounce in the very bad stone cover areas.
Does anyone map BG in order to choose seedrate increases around bad patches?
Some of you guys have far too much spare time on your hands.
You ought to do something productive
