Special Issue Information

Dear Colleagues,

The prestigious MDPI journal Agronomy (IF 3.417) (ISSN 2073-4395) is currently running a Special Issue entitled “Carbon Cycling in Cropping Systems: From Soil to Plant (C Cycling from Soil to Plant)”. As we are acting as Guest Editors for this issue, we would like to welcome contributions from various disciplines. We kindly invite you to consider submitting your full paper to this Special Issue.

Agricultural soils are among the largest terrestrial carbon (C) reservoirs and have great potential to mitigate atmospheric CO2. Understanding C cycling processes in cropping systems would improve mechanism understanding and model predicting of the C fate in the agriculture ecosystem and is urgently needed to better assess the role of agriculture within the Earth system. In this Special Issue, a group of leading experts plan to share their innovative ideas from experimental, observational, and modeling perspectives regarding the turnover, stability, and transfer of C from soil to plant in cropping systems, and their responses to human activities and climate change factors from various spatial and temporal scales.

This Special Issue will mainly address the following scientific issues:

(1) How do C emission and sequestration inventories and the C footprint change in different cropping systems?

(2) How does plant C contribute to soil C turnover and how do soil C cycling and related to plant C?

(3) How do environmental stresses and agriculture practices trigger plant response, soil C cycling, and their interaction?

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Agronomy is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The increases in crop yield in China are linked to massive increases in fertilizer and water input, which have also accelerated the degradation of soil and environmental pollution. Nevertheless, the long-term changes in crop yield and water use efficiency (WUE) of three major cereals (maize, wheat and rice) in response to field management practices are rarely reported. This meta-analysis evaluated the effect of field management (nitrogen input (N), irrigation, fertilizer type, fertilization frequency, and irrigation method) on crop yield and WUE between 1990 and 2020 based on 3152 observations. We found that the N thresholds for maize, wheat, and rice were 150–200 kg ha−1, 140–210 kg ha−1, and 90–135 kg ha−1, respectively. N fertilization within the threshold levels increased the crop yield and WUE of maize (84% and 74%), wheat (47% and 41%), and rice (55% and 30%). The irrigation (mm) thresholds for maize and wheat were 180–240 mm and 300–400 mm and crop yield and WUE were increased by 37% and 13% for maize and by 84% and 41% for wheat. Agricultural management increased yield and WUE (% and %) through drip irrigation (23 and 13 maize; 31 and 14 wheat), alternate wetting and drying (AWD) (26 and 30 rice), split fertilization (31 and 21 maize; 64 and 40 wheat; 33 and 25 rice) and organic–inorganic fertilizer (43 and 39 maize; 68 and 66 wheat; 38 and 34 rice). With the increase in HI (humidity index) from 10 to 30, the contribution of irrigation to WUE decreased, but that of fertilization increased. This study concludes that N fertilizer and irrigation applications between threshold levels along with suitable field management is a win–win strategy to achieve climate-smart agricultural production with minimum damages to soil and environment and at lower dependence on fertilizer and irrigation.
