Storage, Handling, and Moving
Soil chemistry changes over time as biological and chemical processes break down or combine compounds over time. These processes change once the soil is removed from its natural ecosystem (flora and fauna that penetrate the sampled area) and environment (temperature, moisture, and solar light/radiation cycles). As a result, the chemical composition analysis accuracy can be improved if the soil is analyzed soon after extraction — usually within 24 hours. The chemical changes in the soil can be slowed during storage and transportation by freezing it. Longer term soil sample preservation (many months) can be accomplished by air drying.

Famous quotes containing the word moving:
“I’m not making light of prayers here, but of so-called school prayer, which bears as much resemblance to real spiritual experience as that freeze-dried astronaut food bears to a nice standing rib roast. From what I remember of praying in school, it was almost an insult to God, a rote exercise in moving your mouth while daydreaming or checking out the cutest boy in the seventh grade that was a far, far cry from soul-searching.”
—Anna Quindlen (b. 1952)
