The bulk has to be reduced. For solid materials this is done by mixing the whole sample together thoroughly, taking a conveniently sized portion from it and discarding the rest. 2 Handling and Storage The samples must be stored in good conditions pending analysis. The storage conditions that are appropriate will depend upon the type of sample and the determinations required. Most soil analysis, for example, is done on air-dried soil, but the nitrate content can be altered by drying, so nitrate studies are usually done on fresh soil.
Again, if the volumetric flask is not correctly calibrated, the measurements we make with it will be wrong. Incorrect calibration gives systematic or non-random errors in the results. If the error is known and is consistent, we may be able to correct our results by multiplying by a factor. However, it is better to eliminate the systematic error at its source if we can, then we know that the instrument or method in use is correctly setup to give results that are accurate within a specified range of the ‘true’ result.
Clean the auger well, insert it carefully into the same hole and screw it down to the second depth (40 cm). Avoid contamination between successive vertical samples. Place the soil from the second depth into another bucket or bag. Experience shows that there is less variability in the soil at depth, so only about half of the sampling positions need to be sampled at the lower depth. The Sampling Plan, Sample Collection and Preparation 0 0 27 For each area, and each depth in turn, mix together the accumulated soil and carefully sub-sample it down to a convenient amount.
