Increased cropping intensity improves crop residue inputs to the soil and aggregate-associated soil organic carbon stocks
(Elsevier, 2017-01)Many South American agroecosystems are based mainly on soybean [Glycine max (L.) Merr.] as a sole crop in the year, which has increased concerns regarding soil conservation and ecosystems sustainability. The increase in ... -
Stabilization of new carbon inputs rather than old carbon decomposition determines soil organic carbon shifts following woody or herbaceous vegetation transitions
(Springer, 2016-12)Background and aims: Although numerous studies have quantified the effects of land-use changes on soil organic carbon (SOC) stocks, few have examined simultaneously the weight of carbon (C) inputs vs. outputs in shaping ... -
Stover quality and soil organic carbon in long-term nitrogen-fertilized maize
(Alliance of Crop, Soil, and Environmental Science Societies, 2014-09)Nitrogen fertilization often increases maize (Zea mays L.) grain yield but reduces the C/N ratio of stover returned to the soil, which may affect the soil organic carbon (SOC) balance. This study evaluated the long-term ...
