Abstract: Field experiment was conducted to investigate the effects of soil moisture content at plowing M (8.1; 17.1; 26.4% w/w), plowing depth D (10; 20; 30 cm) and plowing speed S (1.93; 10.33 kmh-1) on the porosity of a clay loam soil during the summer season of 2015/2016. Chisel plow was used in seedbed preparation. The layout of the experiment was split- split plots using three replicates. The statistical analysis of the results at the 5% level could be summarized in the following:
a. the effects of the treatments M, S, D; the interaction M×S×D on soil bulk density, total porosity, macro pores and micro pores were significant,
b. the effects of the interaction: S×D were not significant on all the parameters mentioned above,
c. the effects of the interaction: M×D were significant on bulk density and total porosity only and
d. The effects of the interaction: M×S were significant on the macro pores only.
Keywords: (soil moisture, plowing speed, plowing depth, bulk density, total porosity, macro pores, micro pores.)
