Economics- and policy-driven organic carbon input enhancement dominates soil organic carbon accumulation in Chinese croplands

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2018
Significance Soil organic carbon (C) stock in Chinese croplands increased by about 140 kg C ha−1 year−1 from 1980 to 2011. This soil organic C sequestration was largely due to drastic changes in management practices, such as fertilization, tillage, and ...

In low-input and organic systems: Researchers find short-term insect problems, long-term weed problems

open access: yesCalifornia Agriculture, 1994
The conversion from conventional to low-input or organic crop production requires changes in pest control tactics. In a 5-year study, abundance of most pests did not change dramatically between conventional and low-input or organically ...

More replenishment than priming loss of soil organic carbon with additional carbon input

open access: yesNature Communications, 2018
Increases in carbon (C) inputs to soil can replenish soil organic C (SOC) through various mechanisms. However, recent studies have suggested that the increased C input can also stimulate the decomposition of old SOC via priming.
