碳固存和土壤有机质的增加对土壤质量和肥力有直接的积极影响。这项为期两年的研究旨在评估耕作（零耕、少耕、常规耕作和深耕）和氮肥（N @ 0、130、160 和 190 kg ha -1 ）对小麦产量、碳氮固存能力以及土壤有机碳和氮浓度的影响。结果表明，耕作方式对不同土层土壤有机碳和全氮的影响具有统计学意义；土壤有机碳随深度增加而减少。零耕处理的土壤有机碳含量高于少耕、常规和深耕处理。零耕处理耕层（0-15 cm）土壤有机碳储量高于耕作处理。
Carbon sequestration and increases in soil organic matter have direct positive impacts on soil quality and fertility. This two-year study was conducted to evaluate effect of tillage (zero, minimum, conventional and deep tillage) and nitrogen fertilizer (N @ 0, 130, 160 and 190 kg ha -1 ) on wheat yield, carbon and nitrogen sequestration capacity, and soil organic carbon and nitrogen concentrations. The results show that tillage practices had a statistically significant effect on soil organic carbon and total nitrogen at different soil depths; soil organic carbon decreased with depth. Zero tillage treatments had a highly significant soil organic carbon than those of minimum, conventional and deep tillage treatments. Zero tillage treatments had higher soil organic carbon storage in the cultivated layer (0-15 cm) than the tillage treatments.
