Pricing Information

Solum provides a number of pricing options for field moist nutrient analysis

The Solum standard analysis includes: P, K, pH, BpH, OM, S, Zn, Ca, Mg, Na, %BSAT, CEC. Organic Matter (OM) is measured using the loss on ignition (LOI) method. Buffered pH (BpH) is measured using the Sikora Buffer. All nutrients are measured using the Mehlich-3 extractant and an ICP unless additional tests are requested. Solum provides regression information that relates the Mehlich-3 values to the Bray colorimetric method (for P), DTPA method (for Zn) and Ammonium Acetate method (for Ca).

The following additional tests are available and are billed on a per field basis.

  • Bray/Olsen package involves Bray on all samples and Olsen for sample with pH > 7.35
  • Olsen package delivers Olsen results only for samples with pH >7.35
  • Micronutrients include Iron (Fe), Copper (Cu), Boron (B), and Manganese (Mn)

Our pricing discount package is as follows (effective February 1, 2016 to January 1, 2017):
