Analyses With Problematic or Confusing Results

Q. Results occasionally come back on soil and manure/compost analyses that are confusing or potentially flawed. Where can I find examples of these types of analyses so I know when to contact the lab or how to enter the results? (Posted on March 2, 2018)


A. See the Nutrient Management Planning Tools Handbook (, where there are links in both Chapter 2 and Chapter 3 for the “Problematic results and flawed analyses” page. There is a list of scenarios with example analyses and guidance for how to proceed on this page. If you are still confused or have an unusual result that is not listed, feel free to call or email our Nutrient Management Specialists for additional guidance (College Park Staff & Nutrient Management Specialists).
