The Soil Nitrate Quick Test Web-Tool

Location

Click or move the marker to the field where the soil sample was taken. You must choose a field within the agricultural lands of CA (non-shaded region).

Quick Test Value

Enter your pad value from the soil nitrate quick test (ppm). Results are based on top 0-12 in of soil.

Calcium Chloride used in shaking solution

Water-only used in shaking solution

Lab Value

Alternatively, if you have a lab value you may select it here. Results are based on nitrate-N (ppm) in the top 0-12 inches of soil (to translate nitrate to nitrate-N multiply by 0.23).

Bulk Density

The results are based on the in situ bulk density (g/cm³) from the SSURGO database. Values used and presented here are a weighted average of the component types present in the top 0-12 in of soil. SSURGO-estimated bulk density may not accurately represent the bulk density at a site. For better accuracy, update the SSURGO estimate with a recently-measured bulk density value.
