Comparison of aggregates content and carbon proportion of top soil in perennial forage

Carbon storage in cropland soil, a potentially huge carbon pool, accounts for approximately 10% of global terrestrial carbon storage.In croplands, tillage is one of the key drivers behind the degradation of soil stability and leads to the accelerate decomposition of soil organic carbon.Perennial forages are widely accepted as being beneficial to the storage of soil organic matter and the formation of the soil aggregates, which can effectively improve and enhance soil fertility.In this study the carbon sequestration rate was estimated to be on average 0.332Mg.ha‐1.a‐1 after cropland was converted to forage land, this outcome has positive effects in terms of improving sustainable agriculture, including a reduction in CO2 emissions.The purpose of this study was to compare the carbon fixation rates of various perennial forage at different topsoil depths.
