samples to the laboratory), the nitrate results may be erroneously high. Recommended Method for Crushing and Sieving Soils Because soil is defined as having a particle size of less than 2 mm, this sieve size (10 mesh) is recommended for routine soil testing.

Laboratory Sample Pulverizers. The use of a laboratory pulverizer is a must before sending any soil or test sample for XRF, titration, ICP or other assay method; you need to pulverize or fine grind a dry representative portion of the rock sample using what is commonly called in the laboratory language of sample preparation a laboratory pulverizer.
soil sampling program, it is often worthwhile to select the location of soil samples prior to arriving in the field for sampling. These preidentified points can be loaded onto a GPS-enabled device and the GPS can be used to direct you to the sampling location. 6. Continue this process of sample collection at new

Average time is 4-5 minutes per sample. Samples between the size of one and two fists are ground through either grinder depending upon the type of material. All residual material held in either grinder is put with the ground material and thoroughly incorporated. Soil grinding time is from 1-4 minutes per sample.
Weigh and Record Sample • Weigh the soil sample in its bag. [If the sample is too heavy for the scale, transfer about half of the sample to another plastic bag. The weights of the two sample bags will need to be added together. Enter the weight (sum of two bags, if applicable) on the Soil Data worksheet.
