Add-on Soil Testing
Additional standard soil fertility sample includes sample collection, submission and soil amendment and fertilizer recommendations for one main crop: $150
The Standard Test package includes pH, organic matter, base saturation, total exchange capacity, Mehlich III extractable sulfur, phosphorous, calcium, magnesium, potassium, sodium, boron, iron, manganese, copper, zinc, aluminum (*ammonium acetate method available), plus Cobalt, Molybdenum, Selenium, Silicon, Conductivity, and ENR.
Additional soil and leaf tissue lab tests are available. As the needs of each site are unique, please email us for an estimate of recommended lab services and associated pricing.
Plant Tissue: This test is helpful for monitoring nutrient deficiencies and the nutrient uptake capacity of an existing crop. The plant tissue package includes: nitrogen, phosphorous, potassium, calcium, magnesium, sulfur, boron, iron, sodium, manganese, copper, and zinc (starting at $75 per sample).
Carbon to Nitrogen (C:N) Ratio: This lab test is ideal for orchard systems, where carbon can often be high and immobilizing nitrogen. This lab test is also used to identify the nutrient cycling capacity of your system (starting at $35).
Soil paste: The soil paste test is especially important if your pH is already out of ideal range, as bicarbonates and other nutrients in your irrigation lines can contribute towards nutrient excess and imbalances in pH. Soil paste tests are a good indicator of the soluble nutrients that are available in the soil solution and readily plant-available. The saturated paste package includes pH, soluble salts, chloride, bicarbonate, water soluble phosphorous, calcium, magnesium, potassium, sodium, boron, iron, copper, zinc, aluminum, sulfur, and manganese. (starting at $75).
Irrigation Water Suitability: The irrigation water suitability package includes: irrigation water monitoring package, plus nitrate, adjusted SAR, pHc, Phosphorus (starting at $75).
Soil and Water Toxicity: Please inquire about a la carte pricing if you’d like to include tests for specific heavy metals, pesticides and other contaminants.
