Soil compaction is one of the issues that many agricultural lands suffer from.

traffic number of agricultural machinery in the field is one of the main causes of soil compaction.

therefore, the aim of study is to determine the effect of farming systems and depth of work on some of the studied indicators which included porosity, bulk density, soil resistance to penetration, soil resistance to cutting and shaping, number of clods drawbar power, fuel consumption at soil moisture (17-20) % in silty loam soil.

the experiment was conducted in the autumn agricultural season (2021-2022), in one of the fields of Wana sub-district (the village of Qara Kharab) of the Mosul district, which is about (20) km away from it.

the field was designed according to randomized complete block design (RCBD), the factor experiment managed based on split-split block design with four replications.

the main plots were allocated to traffic systems at two levels random traffic framing (RTF), controlled traffic farming (CTF), while the sub plots were allocated to the depth of work were at three levels (10-20-30) cm.

duncan's multiple-range test was used to compare the averages at the probability level (0.05).

the results showed that the CTF significantly reduce energy requirements by (33%, 37%, 38%) compared with RTF for fuel consumption, soil resistance to cutting and shaping and drawbar power, respectively.
