SOIL
ANALYSIS
Soil
analysis has to be carried out by the customer. Special attention should be
paid to this task since the soil is a heterogeneous media. In the
appendix 1 a general sampling scheme is attached. The first
5 cm of soil must be discarded. For most cultures, samples taken from the soil
surface up to 20-40 cm bellow ground are enough to perform the soil analysis.
For lawn and meadows, samples from 5 to 10 cm depth are recommended. On the
other hand, in those cultures having deep roots and fruit trees, soil samples
must be taken from 30 to 60 cm depth.
i) The cultivable layer of the soil should be sampled,
since it is subjected to most amendments and fertilizers and it has been
modified by previous labour.
ii) Analyzed soil samples must be representative of the
area in which the roots are feeding; from soil surface up to 20 to 30 cm below
ground.
iii) Sometimes it is necessary to take the sample
sub-superficially- from 30 to 60 cm. to know the potential capacity of the
soil.
How much soil will be needed to
perform the analysis? This is the most frequent query made by the customers at
our laboratory. From 500 to 1000 grams will be enough to perform all the soil
testing (appendix 2. But this sample should be taken from a higher
soil quantity, mixed in a large container.
