Soil Analysis

Analyses

We perform the following analyses (follow the links for a brief description of the methodology for that procedure)* 

• Crushing and Sieving (S01)
• Crushing and Sieving on Moist/Frozen Soil (S02 - prerequisite for S11)
• Organic Matter (S05)
• pH (S06)
• Soil Fertility Tests (Scoop Volume) (S3-S8)
• Nitrate and Nitrite (S09, S10, S11)
• Ammonium (S10, S11)
• Exchangeable Aluminum (S12)
• Boron, Hot Water Extractable (S13)
• Chloride (S14)
• Available Potassium (S15)
• Extractable/Exchangeable Ca, Mg, Na, K, and Mn (S16)
• Phosphorus, Bray-1 Extractable (for non-calcareous soils) (S17)
• Phosphorus, Olsen Bicarbonate Extractable (for calcareous soils) (S18)
• Sulfate, Extractable (S19)
• Extractable Metals (Cd, Cr, Cu, Fe, Mn, Ni, Pb, Zn) DTPA (S20)
• Mehlich III Extractable Nutrients (S21)
• “Total” Elemental, Microwave (S22A&B)
• Total Phosphorus (S22C)
• Total Nitrogen (S23, S26)
• Organic Carbon (S24, S25, S26)
• Sulfur, Total (S27)
• Mercury, Total (S28) (Not Currently Available)
• Carbonate, Total (S29)
• Cation Exchange Capacity (CEC) by direct method (S30)
• Cation Exchange Capacity (CEC) by summation method (S31)
• Saturated Extract/Electrical Conductance (S32)
• Exchangeable Sodium Percentage (ESP) and/or Sodium Adsorption Ratio (SAR) (S33, S34)
• Percent Moisture (S35)
• Textural Analysis, Hydrometer (S36)
•  
• Extractable Metals, 1 M HNO₃ (S30)
   

*Please note that Test Codes S09 through S36 are done on a weighed soil basis, while the tests performed under Test Codes S03-S08 are done using a soil volume measurement (scoop) rather than a measured weight of soil. Test Codes S03-S08 are the same as the Soil Testing Laboratory’s Routine tests.

At this time we cannot offer organic determinations (i.e. pesticide analyses).
