In what type of container should soil samples be stored?

Soil samples should be stored in a brass or stainless steel tube or a wide-mouth glass jar to maintain the integrity of the sample and prevent contamination. These materials are inert and do not react with the soil, ensuring that the chemical and physical properties of the sample are preserved during storage and transportation. Furthermore, wide-mouth jars facilitate easy access to the samples, making it simpler to analyze or test them later.

Using a container made of brass or stainless steel, as opposed to options like cardboard or regular glass, minimizes the risk of introducing external contaminants that could alter the characteristics of the soil. Plastic bags, while convenient, can retain moisture and potentially lead to degradation or changes within the sample, which could affect test results. Overall, the choice of a high-quality, inert container is crucial for accurate soil analysis.
