Megjegyzések:	The efficiency of four sample processing methods was tested with eight different typesof soils representing the major proportion of cultivated soils. The principle of samplingconstant was applied for characterizing the efficiency of the procedures and testing thewell-mixed status of the prepared soil. The test material was 14C-labeled atrazine thatenabled keeping the random error of analyses ? about 1%. Adding water to the soilproved to be the most efficient and generally applicable procedure resulting in about6% relative sample processing uncertainty for 20 g test portions. The expected erroris inversely proportional to the mass of test portion. Smashing and manual mixing ofsoil resulted in about four times higher uncertainty than mixing with water. Grindingof soil is applicable for dry soils only, but the test procedure applied was not suitable forestimating a typical uncertainty of processing dry soil samples. Adding dry ice did notimprove the efficiency of sample processing.
