Effect of tillage and slurry application on soil quality and CO2 emissions
Agricultural ecosystems generally contain less soil organic carbon (SOC) pool than their potential capacity because of the low return and high rate of mineralization of biosolids, and severe losses due to accelerated erosion and leaching.The depletion of SOC pool leads to decline in soil biological quality and resilience with attendant reduction in biomass productivity, decreased capacity to degrade and filter pollutants, increased risks of soil degradation by erosion and other processes, and increase in emission of greenhouse gases (GHGs).Some farming practices, such as organic fertilization, no‐tillage and legume‐ based rotations can mitigate these problems.The main objective of the current work was to study the effects of the utilization of cow slurry and no‐tillage on soil quality and CO2 emission.We also intend to study the potential of soil microbial activity to assess the effect of these agricultural practices.
