Seasonal variation of macronutrients concentration in Shatt Al-Arab and Al-Ashar Canal

Abstract

Seasonal variation of macronutrients (P, K, Ca, Mg, and S) was studied in waters at two locations, the Shatt Al-Arab and Al-Ashar Chanel, using a device called Inductively Coupled Plasma – MASS SPECTROMETRY (ICPMS). The measured concentrations in two stations for different macronutrients this is ranged as follows: P (4,000-0.090) ppm, K (90.040-8.300) ppm, Ca (286.600-135.550) ppm, Mg (331.330-72.170) ppm, S (458 .300-218.720) ppm. arrange of macronutrients from higher to lower mean content of this study: S> Mg> Ca> K> P
