How agriculture managements influence biogeochemical cycles of soil carbon: processes, mechanisms and ecological consequences
As the largest terrestrial carbon (C) pool, soil C includes soil organic carbon (SOC) and soil inorganic carbon (SIC, mainly solid carbonate). The global soil carbon pool is ~3 times the size of the atmospheric pool and ~4 times the size of the biotic pool. Recently, Earth is becoming more vegetated and biological carbon sequestration is significant. The carbon sink capacity of agricultural and degraded soils can account for approximate 50-66% of the historic carbon loss at the global scale. Similarly, individual countries (e.g. China) have seen SOC increases across agroecosystems over the last decades mainly due to the intensive agricultural activities in terms of nitrogen (N) fertilizers. However, substantial reactive N was involved into the ecosystem and thus significantly accelerated soil acidification at the global scales. This evidenced phenomenon shifted our class view of SIC as an unresponsive carbon pool with a turnover time of millennia. During the last decades, soil carbon pool has gained considerable interest, as a potential solution to combat climate change and to enhance soil fertility. Plenty of case studies have shown the effects of agricultural managements on the biogeochemical cycles of soil C. Nevertheless, few attentions have been paid to the dynamics of SIC cycling and the indirect coupling of SOC-SIC. In addition, the effects of warming on soil C dynamics remain uncertain due to the limited understanding of biogeochemical processes. Hence, there are still knowledge gaps in the understanding how agriculture managements influence biogeochemical cycles of both SOC and SIC.
This VSI focuses on following topics: (i) new methods, techniques and models to accurately simulate the spatiotemporal variation in SOC and SIC stock, especially regarding the agricultural managements; (ii) new knowledge in the origin, formation processes, morphology, cycling and carbon sequestration potential of SIC. (iii) The indirect coupling of SOC and SIC.

Agriculture, Ecosystems & Environment的CAR指数
2023年3月份科睿唯安官方一次性踢除35本SCI期刊，多数涉及学术诚信问题，让我们意识到学术期刊的“被踢”指数，也很重要。目前，对于期刊的“被踢”指数，这里介绍一下：CAR指数（关于CAR的详细介绍，请关注：www.jcarindex.com），这是一种评价期刊学术诚信风险的指数，指数越高代表可能的风险越大。从数据看，Agriculture, Ecosystems & Environment不管是2022年度，还是2023年度的CAR指数，都是比较低的。当然，CAR指数仅供参考，期刊风险情况，需以科睿唯安或中科院预警等官方为准！
