SAMPLING
The following procedure is to be regarded as a guide for obtaining a
indication of the salt content of the soil and of the solutions used in
connection with various culture methods. Samples must be taken in a jar
or bottle which has been carefully cleaned and preferably rinsed out with
demineralized water as any salt residue will cause an increase in the
measured conductivity.

Low The EC of peat substrate is a
Fairly Low measure of the total salt
Normal concentration. A too high EC
High value can be caused by using
Very High salt rainwater or incorrectly
dosed artificial fertilizers.
Evaluation
The EC value of greenhouse soil
samples are an indication of the salt level.
Salty soil can be caused by using salt
Rainwater or artificial fertilizer or by
Very High insufficient watering.
1 EC corresponds to 700 mg/ litre
