Results from the Soil Testing Laboratory

A soil test is not usually performed for the presence of N (nitrogen). Nitrogen can quickly move out of the root zone of the soil by downward movement of water or by plant uptake. Due to nitrogen's potential for rapid changes in availability in the soil, a soil test may show nitrogen levels that no longer exist. Soil Testing Laboratories still provide nitrogen fertilizer recommendations. The recommendations are based on years of research that has determined plant nitrogen needs.

When testing is complete, a report is mailed to you and a copy is sent to the Agriculture Extension Agent for your county or city. Supplemental notes are also sent with the report. The notes explain the technical terms used in the report and provide extra details on fertilizer application schedules and rates for specific kinds of plants. Feel free to contact your Extension Agent for more help on sampling, interpreting soil test results, and understanding how to implement them.
