transmission. The soil sample will require pulverising, either mechanically or with a mortar and pestle, ideally using non-metallic equipment to minimise sample contamination. The disaggregated soil should be passed through a 2 mm stainless steel or nylon sieve and debris removed, such as plant material or stones.

This is the test of choice if fresh soil samples are not available or for soil regions experiencing intermittent strong dry/wet cycles. CO2-Burst respiration is normally 2 – 4 times higher than natural, basal respiration- an effect integrating grinding exposure of organic matter, sieving and osmotic burst effects of sudden rewetting of soil.

The SG 1 soil grinder is designed to grind dry soil samples without comminuting plant inclusions and stones.. Soil comminution in the grinder occurs as result of material particles being crushed by rollers. The grain size of the comminuted product is regulated by the size of the discharge grating openings and depends on the physical properties of the material.

abraded from grinding equipment is another potential problem that should be evaluated. After the soil samples have been dried and sieved, it is then possible to obtain representative subsamples for analysis. Because of the tendency of the bulk sample to fractionate by aggregate size, it is important to thoroughly homogenize each soil sample by some
