摘要:
Wet soil conditions prompted improper drying of soil samples prior to shipment for analyses. Various methods and temperatures were involved in field drying such samples. We accepted that changes in analysis could occur as drying temperatures were elevated. An experiment was run to determine the changes and the magnitude of the changes. An acid Brookston silty clay loam soil was used. P, SO4‐S, Mn and soluble salts can be greatly effected by drying temperatures. Buffer pH, pH, Ca, Mg, Cu and K are slightly effected. OM, Zn, and B are little effected. If samples need drying before shipping, only partial air drying should be employed. Reiteration of basic sample handling methods is needed.
