For determining soil organic matter, what is the best way to store the soil samples until the analysis can be done? Freezing, air drying, cooling or something else?
It is best to store soils air-dry. While air-drying, which can be done at room temperature, you should spread the soil as much as you can to create a vast surface. You should use an oven with circulating air. If you're looking for specific organic soil matter components, the temperature shouldn't rise above 35°C.
Sandeep's response is fine! The only reason for choosing another method would be if you had a particular measurement in mind
Agreed! Store the samples in a cool environment (normal room temperature or slightly below) in sealed containers until you analyze them. They do not have to be refrigerated. Most soil testing laboratories do this as a matter of routine. If stored in excessively warm environments over a long period of time, some of the organic matter might start breaking down to give different results.
It is better to stored air-dry areas;and also we preserve by using oven with recirculating air. CaliberatingTemperature Suit to preserve samples for soil organic matter analysis.
Only freezing can save bacteria and spores. With future chance get live objects back to analysts.
