• The area where the sample is collected must be a maximum of 0.5 ha and homogeneous in terms of texture, soil preparation and fertilization.

• Samples should not be taken at the beginning and / or end of a bed.

• Sampling is carried out in the root zone between two droppers, before the application of fertigation in the morning, at a depth of 20 to 25 cm.

• At the site where the sample is collected, the first 2 cm of the soil surface should be removed to avoid contaminating the sample with solid fertilizer residues.

• A sample is made up of 20 sub-samples  which must be collected randomly in the area.

• The sub-samples taken are placed in a bucket and mixed until a homogeneous sample is obtained.

• From this mixture you take 1 kg (2 pounds)  that constitutes the sample to be shipped to the laboratory
