1 week agoDon't freeze that pre-sidedress nitrate soil test!
The updated recommendation advises that soil samples should not be frozen after collection. Instead, producers and agronomists should keep soil samples cool and ship them to the laboratory as soon as possible after collection. The decision is grounded in recent peer-reviewed research demonstrating that freezing soil samples can significantly alter nitrate test results. Specifically, freezing and subsequent thawing of samples increased measured nitrate concentrations compared to samples that were not frozen.
