Abstract

This study was carried out at a private farm at Wadi El Natroun-El Alamein Road, Behaira Governorate, Egypt on one calcareous soil of Egypt to study the effect of elemental sulphur(S) applications as soil amendment on some soil chemical properties and the contents of available nutrients especially the content of available Mg as well as this soil productivity of faba bean (Vecia faba Giza 716) plant and its content of some nutrients. The used elemental sulphur (S) in this study was obtained from El-Help Company, Egypt, which contains 99% purity S and has a pH (1:5 suspension) of 6.42. In addition, the used magnesium (Mg) was used in the form of acetate MgOAC Mg (CH3COO)2,containing 16,9 % Mg.
