The aim of the present investigation was to improve the productivity of calcareous sandy soil of Arab El-Awammer Experimental Station, Assiut governorate, Egypt.

For this purpose a field experiment under minimum soil tillage conditions in summer season of 2010 was conducted in split split plot design with three replicates to detect the production of maize and soil fertility as influenced by previous and immediately some soil cultural treatments in main plot, levels of powder elemental S (zero and 300 kg S/fed) in the sub plots and mineral nitrogen fertilization levels (120 and 180 kg N/fed) in the sub sub plots.

The four soil cultural treatments in main plots were two different crop sequences with crop residues completely removed (-CR) or with crop residues incorporated in soil surface layer 0-25 cm (+CR).

The different two crop sequences (depend on it's inclusions from legume crop) were:-
