Precision Drilling Cereals

Saw a few drilling trials done like this along with others 15 years ago, the results were broadcast was best despite it looking untidy at all stages, but standard drilling was advised to make sure seed was out of the way of wildlife.
 
It’s been done before. But we are heading for more expensive seed with hybrids etc.
look at which manufacturers are just started to develop precision drills in the last 5 years!

It must be a great solution. The old way of calculating seed rates was OK, however today's soils and equipment make a much better seed bed. Add to this competition for growth and bunching and the losses incurred, I'll bet most would get a better yield by cutting seed rates by 10%, if you precision seed even bigger savings.

The last time this fashion came around about (2001) according to this link to the FW they were supposedly planting at 20 seeds a m2, with 30 tillers per plant and a harvest head count of 600. There was a local guy with a bespoke Stanhay Dart trialling the system, but it was quietly shelved.

When doing my own seed rate trials at 100 seeds m2 I needed 6 to 8 passes of slug pellets and the plot was half a tonne to the acre down at harvest. At 300 and 350 seeds a m2 I needed a single pass. Low rates sound great in theory, but they only work in the lab not in real life.

Sorry, have to disagree, I have seen test plots (and was there when they were drilled) when harvested there was little difference in yield. One had 20% less seed, in a field in Scotland (not the Uni)

Could be a significant saving, spring wheat seed now £550 per ton!

"20% less seed", so 240 m2 seeds versus 300. Thats hardly low rate.

It's a bit like the fashion many people have been led in to for planting wheat in November.
- It works remarkably well - until the year it predictably doesn't work at all.

Only 20% of the expected wheat area planted in England, according to 'the trade' today.
 
Not new. Horsch do singulation on the pronto drills if you want it. Biggest issue is getting seed a consistent size.
Monosem have been able to do this for 60 years , but have just done this 25cm version. Most of the trial drills use Monosem MS ( mini seeder) metering units throughly Europe not just on Monosem frames. Seed size is not a problem to a MONOSEM drill .

Fair enough but not the same design concept as a high speed drill up to 12 metres wide capable of precision planting of all cereals.

The step from fluted rollers to peg wheel should have also come with reduced seed rates, peg wheels onto a means of single seeds placement should come with further seed reductions.

So, I agree with PSQ in that 20% is significant but not huge, so maybe 40% should have been trailed also.

Plant establishment and health is better in addition to less disease and associated costs.

We had the dart out for a trialdrilling sunflower where it did a fantastic job. Spacing was perfect and emergence literally every plant on the same day.
however price put me off buying it
