To evaluate various nitrogen (N) sampling methods and technologies to determine if one method better predicts N needs, leading to higher yields and profitability.

2016 Central Illinois Corn Nitrogen Management Study - 360 SOILSCAN™ vs. PSNT

This study compares the profitability of both a pre-sidedress soil nitrate test (PSNT) and the 360 SOILSCAN™ machine, to that of the PFR standard N program.

The main differentiating factor between the tests was that the 360 SOILSCAN did not offer an ammonium reading.

The difference in recommendations was only 4 units of N between systems. Also the PSNT must be sent to a lab, whereas the
360 SOILSCAN is mobile and can be performed in the field.

The similarity in recommendations and yield results brings peace of mind knowing that the 360 SOILSCAN is a reliable test.
