The effects of the application of different soil conditioners (sulfur
organic
gypsum
fertilizer
and PAM) on soil structure were studied by pot experiment with alkali-saline soil in Pingluo
Ningxia Hui Autonomous Region. All of the four soil conditioners reduced soil bulk density and increased soil total porosity. The improvement of soil physical structure
in combination with water use
promoted the improvement of local alkali soil. The best amount of sulfur was found to be 30.45 g/pot. Great attentions should be paid to soil aeration and prevention of the occurrence of anti-vulcanization. Among the four soil conditioners
