Abstract

Field experiments of this work were carried out in a salt affected heavy clay soil during the 2021 / 2022 season in Arumon, village-Kafr Elshekh Governorate. The of this work to study the effect of the plowing under soil and buried some agricultural waste on the properties of the affected land of the salt. The achieve this goal, the following experiments were used: (1) The plow depth in moles (40 – 50 – 60 cm). (2) Rate buried filed waste (10 – 15 kg/m length) the rice straw and corn stalks as a complete, each single type. (3) Spacing between mole (2 – 4 m) in crossed, compare control field unburied filed. The main results in this study can be summarized in the following points. The minimum bulk density 1.16 g/cm3 with soil at depth 60 cm, spacing between mole crossed 2 m and rate buried waste 15 kg/m on corn stalks. The maximum Soil porosity 75 % with soil at depth 60 cm, spacing between mole crossed 2 m and rate buried waste 15 kg/m on corn stalks. The minimum penetration resistance 265 kPa with soil at depth 60 cm, spacing between mole crossed 2 m and rate buried waste 15 kg/m on corn stalks. The maximum hydraulic conductivity 3.5 mm/h with soil at depth 40 cm, spacing between mole crossed 2 m and rate buried waste 15 kg/m on corn stalks. The minimum soil salinity 3.2 dsm-1 with soil at depth 60 cm, spacing between mole crossed 2 m and rate buried waste 15 kg/m on corn stalks.
