Effect of heavy machinery operation on soil three phases and available nutrients in Chinese Mollisols
In the past 5 decades, Europe, the United States and other developed countries achieved agricultural mechanization. This made mechanical tillage being an important component of sustainable agricultural development ( Ding et al., 2006). However, the damaged soil environment and soil degradation during the mechanization processes, especially in the subsoil compaction has been the worlds major concern to agriculture (Alkukku et al., 2003). The interference of mechanical tillage on soil structure is complex. The selection of tillage machinery and crop systems determine the character of soil structure directly, and affect the soil tilth and the fertilizer application (Pagliai et al., 2004).
