Preparing the Sample

Soil Sample with Spoon
  • Use a clean trowel or knife to collect the sample, following the guidelines in the manual.
  • Once the samples are collected and properly mixed, the sample should be air dried at room temperature.
  • Do not attempt to dry samples in an oven or microwave.
  • Remove and discard leaves, sticks, stones, etc.
  • Crush any lumps to achieve a more uniform sample size using the back of a spoon.
  • Samples can be sifted through a wire screen if desired.
  • Properly dried and crushed samples allow for a more thorough "extraction" of the available nutrients.
