Soil spectroscopy

Dear colleagues,

as topicality is rising on application of soil spectroscopy for routine analysis by utilizing own created or shared spectral libraries, I am interested if someone could share their knowledge on instrumentation choice? Could someone share their experience with Visible to Near- , Mid-Infrared Spectroscopy instrument models or key parameters to evaluate when choosing instrument for purchase?

Kind regards,
