Watch: Limitations When Soil Testing for Sulfate Sulfur

Farmers have long been told that nutrient management strategies should be science-based and guided by soil testing.

However, this can be a challenge when it comes to testing for sulfur levels in the soil… because sulphur doesn’t necessarily play by the rules.

In this video, independent agronomist Ray Dowbenko reveals the limitations when soil testing for sulfate sulfur. He explains why the results may not account for elemental sulfur that is yet to be converted to sulfate, how sulfur levels can vary across a field, and how sulfate mobility can impact measurements.

Dowbenko reminds farmers that soil test interpretation is also highly subjective, which is why you should work with an agronomist who knows your fields.
