32. Soil sampling must be conducted as follows:(1) 3 successive samples of around 10 cm, including surface litter (LFH horizon), must be taken to a depth of about 30 cm around micro-plots 4 and 6 of the plan in Schedule A;
(2) once a sample has been taken and before the next sample is taken, the promoter must measure the depth of the hole to the nearest 0.25 cm, to ascertain the depth of the soil taken for each of the 3 samples;
(3) the samples must be taken using a volumetric probe with a diameter of at least 5 cm for quantitative sampling. When it is impossible to take a volumetric sample, the soil samples must be taken using a Dutch auger;
(4) the colour of each soil sample must be determined using a Munsell soil colour chart;
(5) each successive soil sample must be stored in a bag or rigid container before being sent to the laboratory for analysis, on which the promoter must inscribe the cruise line number and sample plot number, sample number and sampling zone (0-10, 10-20 and 20-30);
(6) the promoter must, in particular, enter the cruise line number and sample plot number, the sample number, the sampling zone (0-10, 10-20 and 20-30) and the soil colour code in the compiled inventory report for the project;
(7) the distance between 2 samples taken during different sampling campaigns must be at least 1 m.
