Abstract
A field experiment was conducted at the experimental farm, Faculty of Agriculture, Al-Azahar University, Assuit, Egypt which is located at 27^° 12^- 16.67⁼ N latitude and 31^° 09^- 36.86⁼ E longitude for two successive sunflower growing seasons of 2011 and 2012. This study aims to asses the effect of soil management practices (conventional, reduced and no tillage) at different soil moisture content (65 and 85 % of field capacity, F.C.) with two fertilizer types (urea and ureaform) on soil carbon dioxide flux in order to mitigate its effect on global climate changes as well as sunflower growth.
