Special Issue Information

Dear Colleagues,

By 2050, the global population is expected to reach 9.3 billion. To meet the needs of this growing population, food production must increase from the current 8.4 billion tons per year to approximately 13.5 billion tons per year. Agriculture is facing unprecedented pressure due to the increasing scarcity of resources such as land, water, and energy, as well as the threats posed by global change. Soil constraints such as acidification, salinization, erosion, nutrient imbalance, poor physical structure, shallow tillage layer, low biological function, decreased water and fertility retention capacity, and soil pollution can easily cause land degradation. Land degradation constrains sustainable agricultural development and food production. Existing soil improvement methods include engineering improvements such as water conservancy projects, agricultural engineering, and water-saving irrigation; agronomic practices such as soil amendment application, organic material return, optimization of tillage and cultivation methods, and planting of high-quality crop varieties; and biotechnology such as organic fertilizer application, bio-tillage, cover crop planting, and diversified cropping. The above soil improvement theories and technologies mainly target changes in soil properties and constraint mitigation. In recent years, the response and feedback of soil, crops and organisms in the soil improvement process have received increasing attention. Due to different natural conditions and economic development levels in different regions, soil improvement technologies are more focused on technical matching and economic efficiency. With the increasing attention paid by society to the ecological environment, environmental friendliness and sustainability are also future trends in the field of soil improvement.

Therefore, this Special Issue aims to explore the impact of soil degradation on sustainable agricultural development and new principles, technologies, and models for soil improvement and crop productivity increase.

For this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

(1) Assessment and key indicators of soil degradation;

(2) Physical, chemical, and biological degradation processes and mechanisms of soil;

(3) Occurrence and hazards of soil pollution, soil-borne disease, etc.;

(4) New principles and technologies for engineering, agronomy, and biological soil improvement;

(5) Application of soil amendments, organic fertilizers, microbial agents, and other products;

(6) Soil–crop–biological interaction in the process of soil improvement;

(7) The impact of diversified cropping and ecological planting on soil health;

(8) The influence of soil improvement on crop yield and quality.

We look forward to receiving your contributions.

Green manure (GM)–rice–rice rotation is an important management practice for improving soil fertility and rice productivity. The microbiological mechanisms for the increase in grain yield in GM–rice–rice rotation remain unclear. The responses of soil biodiversity, bacterial and fungal communities, and their interactions in the GM–rice–rice rotation were investigated based on two long-term field experiments in Gaoqiao (GQ) and Nanxian (NX) in Hunan Province, south China. Results showed that rice yields were raised by 11.79% and 15.03% under GM in GQ and NX, respectively. GM promoted Shannon diversity and Pielou’s evenness and changed the community structures of bacteria and fungi. The co-occurrence network analysis found that the percentages of negative edges were higher in GM (40.79% and 44.32% in GQ and NX, respectively) than those in the corresponding winter fallow (34.86% and 29.13% in GQ and NX, respectively) in the combined bacterial–fungal networks, suggesting more stable microbial community under GM. Moreover, GM had higher percentages of bacterial–fungal and fungal–fungal edges than winter fallow, indicating that GM increased the interaction between bacteria and fungi and fungi play more essential roles in affecting soil processes under GM. The keystone taxa in GM were positively linked with C metabolism-related enzymes and soil multifunctionality, and were important in improving soil fertility and rice productivity. We concluded that the fungal community was more sensitive to GM application than the bacterial community and that keystone taxa had important influences on soil properties and rice productivity in the GM–double-rice cropping system, which can effectively support the sustainable development of the paddy field ecosystem in southern China.

To investigate the effects of straw residues with reduced nitrogen (N) fertilizer on greenhouse gas (GHG) and N losses in paddy fields, we conducted a field experiment during two growing seasons in paddy rice systems in southern China to evaluate the impacts of the application of straw residues with reduced N fertilizer on rice yield, GHG emissions, and ammonia (NH3) volatilization. The four treatments included N100 (conventional dose of N fertilizer), SN100 (conventional dose of N fertilizer + straw), N60 (60% of the conventional dose of N fertilizer), and SN60 (60% of the conventional dose of N fertilizer + straw). We found that the yield of the SN60 treatment was slightly reduced, but the partial factor productivity of applied N (PFPN) was significantly increased by 63.9% compared to the N100 treatment. At the same N application rate, the application of straw increased soil organic C (SOC), methane (CH4) emissions, carbon dioxide (CO2) emissions, global warming potential (GWP), greenhouse gas intensity (GHGI), and net ecosystem carbon budget (NECB), but significantly decreased soil N2O emissions and NH3 volatilization. Compared with conventional fertilization (N100), straw residues with reduced N fertilization (SN60) reduced N2O emissions and NH3 volatilization by 42.1% and 23.9%, and increased GHGI and NECB by 11.1% and 18.3%, respectively. The results indicate that straw residues with reduced N fertilizer are a feasible strategy to reduce N losses in paddy fields while increasing carbon sequestration. Full article
