Abstract.

High energy consumption and compaction are two major issues concerning agricultural machinery promotion and crop production, respectively. In order to explore the effects of vibrating sub-soiling on soil physical properties, and traction resistance, the experiment was conducted with three treatments, i.e. rotary stillage, vibrating subsoiling and non-vibrating subsoiling in Gu’an, Hebei province in 2011. Experiment results showed that: vibrating subsoiling decreased bulk density and penetration resistance values by 9.58% at 30-45cm and 10.21% at 15-30cm in comparison with rotary tillage and non-vibrating subsoiling, respectively. Meanwhile, the water content significantly increased by 17.68% and 9.48% at 30-45cm compared with the other two treatments. What’s more, vibrating subsoiling had a higher soil disturbance coefficient and the average decreasing range of its traction resistance was 23.81%.In conclusion, vibrating subsoiling management practices can improve soil properties and effectively decrease traction resistance, so it may be a more sustainable approach to framing in Hebei province.
