True or False? Soil samples should be dried in a warm oven before they are submitted.

The practice of drying soil samples in a warm oven before submission to a laboratory is not a standard requirement. Generally, soil samples should be handled properly to maintain their natural moisture content, as altering the moisture level can affect the chemical and physical properties of the soil, leading to inaccurate test results. Laboratories often have specific instructions on how to collect and prepare samples, and many prefer soil to be sent in its natural state without drying.

Certain tests might indeed require specific preparation, but this does not translate to a blanket requirement for all soil samples across the board. As a result, indicating that soil should be dried is inaccurate, leading to the conclusion that this statement is false.
