Interesting result from the single wheat field I ran a Soyl Sense trail on this year, by no means scientific but its seem to have out yielded its otherwise equally treated neighbours pretty consistently

I have a similar result from a single OSR filed that we also ran a comparison on

And presumably you would normally expect that field to do about the same as the others?

Here is the OSR VRA vs no VRA yield maps - not quite so dramatic but I think the VRA field (the biggest at bottom of map) is the highest despite not being the best soil, I would normally expect that field to be the worst of this block

First year farming this new block of land so I cant answer that - its pretty consistent in terms of soil type, topography, fertility and history though so I really wouldn't expect much difference on the face of it

I did say this was a rather unscientific trial !

Can you put a figure on the %age improvement?

Will look in more detail when in the office next but on the wheat map it looks like it could be geting in for 1t/ ha in this case

Pretty impressive IMO, and as a ex n sensor user for about 5 years in the past feel I have to revisit this now based on the above

I've been trialling VR N for 3 years now. Last year was the first time I got a yield increase in wheat using the canopy model system. What did you use Clive?

That didn't answer my question

Changing the subject, how do you select more then one field for maps in Gatekeeper? I can only do one field or every field in that job.

sorry read it wrong - we used canopy model

re gatekeeper just tick this box

Thanks. I agree that the Canopy model is probably the best, but yet agin it didn't bring the total field yield t/ha to more than the flat rate - in fact, it yielded less...

With 1 positive result out of 9 trial fields over 3 seasons that's not encouraging me at all.

I put my entire harvest into 4 jobs for 4 crops with dozens of fields in each job, which nearly melts the computer in producing the maps. I guess I'll have to split the jobs up to get a more meaningful way of displaying it.

I break it down in jobs by variety and block so end up with a fresh card each day pretty much, too much data on one card in not a good idea IMO if something corrupts etc

I find that Greenstar & Gatekeeper don't communicate that well when it comes to jobs, so just let the 2630 screen record everything then sort it out in the office on a rainy day.
