Therefore, every garden owner should make use of the opportunity, to have his soil examined in one of the special laboratories set up for this purpose. Only mixed samples from a specific area are sent in for testing. Of each 100 m2 of garden land is taken 5 to 6 single samples, whereby the tapping points are to be distributed as evenly as possible over the area. The samples are taken either with a spade or a special sampler and are intended to record a narrow strip of soil from the top 20 cm of the topsoil. The 5 or 6 Individual samples are placed in a vessel, mix them well and take the actual sample from it (mixed sample) von 50 g, which is sent to the testing laboratory. On very uniform ground or when there are no special requirements, the individual samples can also be taken from a larger area (200 to 300 m²) be combined into a mixed sample. The best time for sampling is autumn. Of course, you shouldn't fertilize beforehand. The soil test should be carried out regularly every two years.
