Increasing soil carbon storage in agroecosystems under low nutrient inputs

Agriculture has to reduce synthetic inputs. Consequently, ecological processes and alternative agricultural practices will become the main regulators of carbon (C), nitrogen (N) and phosphorus (P) in cropped soils. Scientists Bertrand et al. recently observed that soil C storage is constrained by N and P supplies in various agricultural situations. Several agroecological practices that improve nutrient recycling can resolve this constraint.
