What is the Difference between air dried and oven dried soil sample?

Air dried soil samples are dried naturally at room temperature, while oven dried soil samples are dried using an oven at a controlled temperature. Air dried samples may retain some of the soil's original properties better, while oven dried samples may be quicker and more consistent in removing moisture. The choice between the two methods depends on the specific research objectives and sample characteristics.


Why is it not recommended to leave an oven-dried sample in the open air for a long time before measuring its dry weight?

Leaving an oven-dried sample in the open air for a long time can lead to reabsorption of moisture from the environment, leading to an increase in the sample's weight. This can result in inaccurate measurements of the sample's dry weight and affect the validity of the experiment's results.


Why must a sample be vacuum dried before addition of the sample application buffer?

A sample must be vacuum dried before the addition of the sample application buffer to remove any residual moisture that could interfere with the sample's behavior during analysis. Moisture can affect solubility, lead to inconsistent results, and cause unwanted reactions with the buffer components. Vacuum drying ensures that the sample is in a stable, concentrated form, allowing for more accurate and reproducible experimental outcomes. Additionally, it prevents dilution of the sample when the buffer is added, optimizing the effectiveness of the application.
