Target Soil Nitrate Sample Timing ------------------ Soil Nitrate (ppm) ------------------
Location	Previous Crop	Soil Texture	Planting	V1-V2	V3-V4*	V6	V9
* V3-V4 represents the "typical" sample timing that Ontario PSNT recommendations have been developed with.
DISCLAIMER - These results represent soil nitrate levels collected from a small area at each location. Soil nitrate results are strongly influenced by environment (precipitation, temperature) and field characteristics (soil texture, organic matter, previous crop etc.). These values are for observing changes in soil nitrate concentrations within a location over time only and should not be used for recommendation purposes on your own farm. If you would like to use the PSNT test, it is important to sample your own farm. Guidelines for sampling available here.
