Effect of Salinity on the Uptake of Some Nutrients in Some Selected Soils of Egypt

An population increases, the need for food production rises concomitantly. An indirect effect of salinity is its influence on soil microflora. Microorganisms activities such as ammonification and nitrification could be inhibited by salinization. Irrigation with saline water may indirectly, case an increase in the soil PH which could depress the availability of some miconutrients The objectives of the present study are to Texamine the extent to which application of K, p, Mn, Z, and Fe can contribute to the improvement of growth and increase in the dry matter yields of corn (Zea mays L.) plants under saline conditions.Also, the changes oceurring in micronutrients content of these plants after addition was studied. Also, the hydrolysis of urea under saline conditions is also included in this study.
