A soil sample for microbiological analysis should ideally be

  • A.Frozen and thawed several times
  • B.Kept cool and moist and analysed promptly
  • C.Air dried and stored for several months first
  • D.Autoclaved before analysis

Answer: B

Drying, heating or repeated freezing all change the community before it is measured, and storage lets the population shift. Keeping the sample near field moisture at a low temperature and analysing it quickly gives the closest picture of the soil as it was.
