- Abstract
Two experiments were conducted on the saline sodic soil at the Agricultural Research Center Farm - south of Port Said the EC for this land was 42 dSm-1 and the pH 8.5 and the ratio of ESP 37.16 %, which is a heavy clay land, One of them is a laboratory experiment in the columns to determine the efficiency of the materials used and control the method of carrying out the experiment during the summer season, 2019 from April to December. Also taken the same soil during winter 2019/2020. The soil amendments were organic matter and gypsum. The addition of organic matter at a rate of 30 m3/fed determined, where the different size was reduced to the extent possible and then separated into volumes through separation sieves, and the addition organic matter according to the density of each volume after separation: The first volume use the organic matter in the coarse size without separating. The second volume of the organic matter was separated into a volume less than 2 mm and greater than 1 mm. Third size which is the soft size where the volume was less than 1 mm. The amount of gypsum added at rate 12.46 Mg faaed-1 was determined according to (GR = ESPi - ESPf / 100 (CEC * 1.72)). In the laborite was divided volume of the previous organic matter has been separated into three parts.
