As far as I understand there is no easy way to measure all the micro-nutrients through the sensors in the field. Some of this, N,P,K, can be measured but bit tedious.
Actually we are also looking for such a sensor so the "soil testing" becomes much easier.
The short answer is no. Intensively calibrated IR is useful but will not give you all you want.
