What can you use to sample soil?

Using glass jars for soil sampling is appropriate due to their non-reactive properties, which help preserve the integrity of the sample. Glass is inert and does not leach chemicals or contaminants into the soil sample, ensuring that the results of any subsequent analysis accurately reflect the soil’s true composition. This is crucial when examining soil for lead contamination or other hazardous materials, as even minor contamination could skew results.

Other materials may not provide the same level of reliability. For example, cardboard boxes can absorb moisture and contaminants, potentially altering the sample. Metal containers might introduce chemicals or elements that could interfere with the testing process, particularly if the metals are reactive or if the soil is acidic. Cotton bags, while breathable, can allow some moisture and contaminants to affect the sample and may not maintain the soil's conditions as effectively as glass jars.

Overall, the choice of glass jars aligns with best practices in environmental sampling, ensuring accurate and meaningful testing outcomes.
