英文摘要	Phosphorus is an essential nutrient for plants, and consequently has great influence on agricultural productivity. Rock phosphate as natural mined rock is distributed in many localities in the world and in the western desert in Egypt. The importance of the rock phosphate is related to its high content of phosphorous element from 16 to 20% according to the source of mine. Several approaches and techniques have been followed for the treatments of rock phosphate to get benefits of its content from available phosphorus. In this experimental research, three natural materials have been applied to be mixed with the rock phosphates to obtain available phosphorus through incubation time from 0-120days. Organic cattle manure has been added to the pots of calcareous samples at rates of 0 to 10.0% and kept for 120 days. Another batch of the experiment has been treated with sulfur doses from 0 to 2% mixed with the rock phosphate.The ammonium zeolite at rates of 0 to 20 g/Kg have been added to the calcareous samples and incubated at intervals30,60,90 and 120 days. The valuable information obtained from these laboratory experiments refer that mixing the rock phosphate with cattle manure (45.23 organic matter at rate of 5.0 to 10.0% increased the available phosphorus due to the formation of Ca and organic matter complex and chelating capacity of organic acids.The successful treatment with sulfur on the availability of phosphorus is related to the oxidation of S to sulfuric acid and reacts with calcium phosphate and calcium carbonate ending to release of phosphorus. The addition of 2.0% S resulted in the highest concentration of available P after 60 to 120 days. The specific nature of zeolite with its high CEC surface area particularly after treatment with ammonia proved to be very efficient for their application in mixing with rock phosphate to increase available phosphorus in the calcareous soils.
