Soil test interpretations (according to information available at http://ag.arizona.edu/crops/cotton/soilmgt/saline_sodic_soil.html; http://aces.nmsu.edu/pubs/_a/a-122.html; Personal communication by Dr Abdelmajid Zouahri, INRA, CRRA, Rabat, Morocco):
bFor EC: Saline soil = EC > 4 ds/m; Normal soil = EC < 4 ds/m
c For Mn: low = <1.0 mg/Kg; moderate = 1.0-2.5 mg/Kg; high = >2.5 mg/Kg
d For Zn: low = <0.5 mg/Kg; moderate = 0.5-1.0 mg/Kg; high = >1.0 mg/Kg
e For Cd: all the soils samples above the normal level (0.01 mg/Kg of soil)
