Area Of Science
- Agricultural Science
- Soil Science
- Ecology
Background
- Soil multifunctionality is crucial for agricultural productivity and sustainability.
- Optimizing agricultural practices to enhance soil multifunctionality is essential due to increasing global food demand.
- The combined effects of crop rotation and fertilization on soil multifunctionality are not well understood.
Purpose Of The Study
- To investigate the impact of different crop rotations (paddy-upland vs. dryland) combined with fertilization (chemical fertilizer vs. manure) on soil multifunctionality.
- To analyze the effects on soil microbial community structure and microbial networks.
- To identify the optimal combination of practices for maximizing soil multifunctionality and crop yield.
Main Methods
- A two-year field experiment was conducted comparing rice-wheat (paddy-upland) and maize-wheat (dryland) rotations.
- Treatments included chemical fertilizer and pig manure application.
- Soil multifunctionality, microbial community structure, and network properties were assessed.
Main Results
- Paddy-upland rotation combined with manure application demonstrated the most significant enhancement of soil multifunctionality (216.25% increase).
- This combination also led to a substantial crop yield increase (222.71%).
- Paddy-upland rotation and fertilization positively influenced soil bacterial network complexity and robustness.
Conclusions
- The combination of paddy-upland rotation and manure application is an optimal strategy for improving soil multifunctionality and crop yield.
- Soil microbial network properties are key predictors of soil multifunctionality.
- This research offers insights for sustainable agriculture by enhancing soil health through integrated management practices.

Microorganisms play a pivotal role in maintaining ecosystem balance by recycling essential elements such as carbon, nitrogen, and phosphorus, as well as supporting processes like bioremediation, wastewater treatment, and biofuel production.Microbes in Elemental CyclesIn the carbon cycle, microorganisms decompose organic matter, releasing carbon dioxide via aerobic respiration. This carbon dioxide is subsequently used by photosynthetic organisms to synthesize organic compounds, closing the...
Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend not only on the chemical constituents but also on the presence of living organisms. In general, soils contain three major components:
Inorganic mineral matter, which constitutes about 40 to 45 percent of the soil volume.
Organic matter, also known as humus, which makes up about 5 percent of the soil volume.
Water and air, covering about 50...
