But some experiments may be altered by deposition of ions or other components whilst drying. For that reason you'll be able to test exchangable ferrous ions, exchangable Potassium, pH, and many others. on moist samples instantly just after collection. Grinding: Within an agate motor, motorized grinder, picket morter, and so on. grind the dried soil aggregates properly.
