360 SOILSCAN: Comparable Accuracy to Traditional Labs

Do you know how much nitrogen is in your field? As the season progresses and conditions change – especially with heavy rainfall events – knowing in real-time how much N is left is a huge advantage. 360 SOILSCAN, an in-field nitrate testing system, gives you more control so you know how much N you need to finish the season strong.

Not only does 360 SOILSCAN give you real-time data, it has accuracy comparable to traditional lab testing. To prove it, 360 Yield Center has participated in the Agricultural Laboratory Proficiency (ALP) Program in the fall of 2014 and the spring of 2015.

ALP is a national proficiency testing program that monitors soil analysis for consistency, accuracy and reliability. Participating labs receive homogenized, dried and ground standardized soil samples, measure the samples and report results back. The results are compiled and compared to the other lab participants.

In both the 2014 and 2015 ALP programs, 360 SOILSCAN reported results consistent with the standardized soil samples and the results were well within the range for all participating laboratories. The charts below show a breakdown of our performance according to each standardized sample.
