Abstract:
Human attempts to increase food production have had a lasting impact on our environment. Prolonged reliance on traditional farming methods, particularly those involving extensive tilling and the removal or burning of crop residues, has exacerbated soil erosion and led to the gradual degradation of our soil resources. This situation has paved the way for the emergence of conservation agriculture (CA), a widely embraced set of management principles that promise more sustainable agricultural production. The importance of CA becomes even more pronounced as it plays a pivotal role in both adapting to and mitigating the adverse effects of climate change on agriculture and the environment. CA practices have demonstrated substantial effects on the dynamics and distribution of soil organic carbon (SOC) and nitrogen, in addition to enhancing and maintaining crop yields. Achieving a noticeable increase in SOC and achieving satisfactory productivity effects through CA requires an appropriate period for SOC accumulation. Consequently, the advantages of CA may not become apparent right away. So, long term experimental research can only provide us the accurate picture. Therefore it is necessary to discuss about the dynamics of nitrogen and carbon in long term CA based experiments.
