| Standard Nutrient Analysis (Modified Morgan) | This test measures plant-available nutrients (calcium, magnesium, phosphorus, potassium, sulfur, iron, manganese, copper, zinc, aluminum, and boron) using the Modified Morgan extractant, plus soil pH and buffer pH. It also includes lead screening, estimated cation exchange capacity (CEC), % base saturation, and crop-specific lime and fertilizer recommendations. Recommended for lawns, gardens, ornamentals, fruits, agronomic crops, and nursery crops grown in mineral soil. Not suitable for compost or soilless media. | $18.00 |
| Standard Nutrient Analysis with Expedited Processing | Standard Nutrient Analysis with expedited processing (5-business-day turnaround upon sample receipt) | $58.00 |
| Comprehensive Standard Nutrient Analysis | A more complete nutrient and soil health snapshot: Standard Nutrient Analysis plus soluble salts, organic matter, and plant-available nitrogen (nitrate-N and ammonium-N). | $45.00 |
| Soil pH ONLY | Measures soil pH and provides lime recommendations to raise pH or sulfur recommendations to lower pH. | $7.00 |
| Soluble Salts | Total soluble salts are determined using a 1:2 V:V electrical conductivity method. Interpretation is provided. | $7.00 |
| Organic Matter Content | Soil organic matter (%OM) is measured by loss-on-ignition for soils or composts. No recommendations are provided. | $10.00 |
| Soil Textural Analysis | Measures sand, silt, and clay by the hydrometer method and assigns a USDA soil textural class. No recommendations are provided. | $20.00 |
| Pre-Sidedress Soil Nitrate Test (PSNT) | PSNT measures soil nitrate-N to guide in-season N rates for silage corn, sweet corn, and pumpkins (also useful for turf). For samples received from June 1 through mid-August, results are typically ready the next business day, and growers are notified of results and N recommendations by email, fax, or phone. | $12.00 |
| End-of-Season Cornstalk Test | Nitrate-N is measured in properly collected cornstalks at harvest to assess whether in-season N was below optimum, optimum, or above optimum. Often used alongside the PSNT. | $12.00 |
