Rare studies have been carried out on the use of Phytoavailability Soil Test (PST) using ion exchange resin capsules in calcareous soils. Resin capsules were used to monitor P efficiencies due to Vascular Arbscular Mycorrhiza (VAM) inoculation and sulfur application in calcareous soil. Surface soil samples (0-30 cm) were collected from Nubaria region. Corn was used as a test plant. The obtained data showed that RAQ-P (Resin Adsorption Quantity) value increased with increasing soil P supply. Generally, the highest concentration of available –P was obtained after 60 days of adding P. Also it is clear that the RAQ-P value decreased at the third time (after 45 days) relative to the first time (15 days). RAQ was higher in mycorrhizal corn plants than the non-mycorrhizal. Also increasing S levels significantly increased P-RAQ. The highest significant P-RAQ was recorded with the treatment of 100 kg P Fed-1 + O.M and 100kg S inoculated.
