How much is a 2nd hand passive Yara N Sensor worth? Complete with X20 screen.

Not much , why you selling ?

I'm not selling. Just need to know a fair value for it.
OK , I looked at buying one but agronomist said wouldn't pay for itself ? What's your experience

Precision Decisions are/were advertising ex-lease models for £4500 incl installation and a year's licence
Anyone know what acres you would need to justify one ?
X20 no longer supported and old, flaky tech now
If it fails (they do ) the sensor all but worthless
X20 failed in our Bateman last year, couldn't repair or replace so had to spend 7k on a x30 and ecu. X30 won't work with n sensor
I would look to spend the money on a satalite service if I were you !
Passive sensor is also a VERY limited in working hours - fine if you don't have much to do but it drove us mad when we ran one, weather and ground conditions are limit enough without having to wait for the sun to be in the right part of the sky !

I see you had one advertised in Classifieds on here recently for £3000. Is it yours, or are you linked to PD?

Anything over 150 ould justify an N-Sensor

X25 and X30 will both work with N-Sensor sometime in March 2017 as Topcon are releasing an X-Links unlock feature for them.

this might slow the crop spec infestation.

150ac?

Yeh you would really need to be over 150Ha to be seeing a good return on investment, but it will even up field variability and reduce lodging on all areas.

Depends on cropping. In cereals I don't think you save any fert. It is just applied more accurately according to crop need. as a combine driver I can tell you that crops are much more even across the field. Poor areas are better and good areas are less prone to lodging. It can be used to variably apply PGRs and fungicides according to crop biomass but again it is difficult to quantify savings or yield increases.
The biggest and most quantifiable payback is on oilseed rape. When used in Absolute N mode we have saved as much as 100kg/ha over the rates calculated by RB209 etc when crops have been big coming out of winter.
At the prices quoted elsewhere in this thread I would be happy to buy one for 400ac upwards of cereals and osr.
wondered what would happen when all the 20's eventually died !

I don't know about the redundancy of the X20 so can't comment.
You are perfectly correct about the limited working hours of the passive sensor, especially early in the year, when day length is shorter. You can, however, still apply fert at flat rate until the sun is high enough. Just pick the least variable fields. The degree of this inconvenience depends on how many acres you have to cover. You pays your money.....

the sensor is primarily for correcting variability therefore increasing yields, not to save on fert, however on areas over 200ha this has seen a saving.

No link to PD, its mine. Potential buyer alerted me to PD's offer
can't say I ever had constantly measurable higher yield over the years we use N sensor or lowered fert costs, it did seem to improve evenness of crop though
The limited working hours of a passive sensor really was a big limit though and I don't see the point in one today over satellite images which have got cheaper and more regular , have no capital cost and will soon replace NDVI with SAR
