Is anyone using an N sensor? How long have you had it? Anyone stopped using one? Do they work and are they worth the investment?

I personally don't like satellite as it stands today. Too many shading issues and not real time.
I take your point about shading - do you mean cloud cover or a better side view of the crop a few feet either side of the tractor?
How do fertiliser logistics work with an N Sensor? Do you work on creating the ideal canopy so over order on fertiliser just in case then hope to reduce the doses in the field? How do you calibrate the dose rate? Excuse the questions - I'm genuinely interested in how it works.
Isn’t the problem with any scanning method the huge range of potential yield from any given canopy? Can this process ever be more precise than an experienced grower/agronomist making an assessment of the crop? I can see the point of altering applications by soil type, but surely that can be done from soil maps?With the Isaria (front mounted sensor) we advise scanning a decent canopy at this time of year so the sensor can measure the potential of the crop. If you scan at same time as first application after a harsh winter or several frosts the canopy will be reduced and suggest less potential.

Ran one many years ago when they first came out, the passive srvsor is very restrictive in spreading hours, active is better. However there are much better ways to do vra N now - SAR is a better approach re agronomy model and not cloud affected which is what we do now
Pardon my ignorance Clive but what is SAR?
SAR supposed to be a lot better than the alternative imagery although some SAR images have been effected by cloud cover this year so not bullet proof for reliability.
How can cloud effect a radar ?
