Potential effect of key soil bacterial taxa on the increase of rice yield under milk vetch rotation
Summary
A long-term paddy field experiment found that milk vetch rotation enriched key phosphate-solubilizing bacterial taxa including Vicinamibacterales, which correlated positively with soil phosphorus availability and ultimately with increased rice yield.
Legume crop rotation is often adopted in rice cultivation to improve soil productivity. However, little is known about the role of microbes under legume rotation in affecting soil productivity. To elucidate this, a long-term paddy cropping experiment was set up to study the relationship between crop yield, soil chemical properties, and key microbial taxa under a double-rice and milk vetch rotation. Milk vetch rotation significantly improved soil chemical properties compared to no fertilization treatment, and soil phosphorus was a major factor correlated with crop yield. Long-term legume rotation increased soil bacterial alpha diversity and changed soil bacterial community. After milk vetch rotation, the relative abundances of Bacteroidota, Desulfobacterota, Firmicutes, and Proteobacteria increased while those of Acidobacteriota, Chloroflexi, and Planctomycetota decreased. Moreover, milk vetch rotation increased the relative abundance of phosphorus-related gene K01083 (bpp), which was significantly correlated with soil phosphorus content and crop yield. Network analysis showed that taxa of Vicinamibacterales were positively correlated with total phosphorus and available phosphorus, which was a potential taxon contributing to the availability of soil phosphorus stock. Our results indicated that milk vetch rotation could enrich key taxa with latent phosphate-solubilizing ability, increase the content of soil available phosphorus, and finally enhance crop yield. This could provide scientific guidance for better crop production.

Researchers used culturomics and amplicon-based metagenomics to characterise bacterial communities in rhizosphere and bulk soils of high-yield Oryza sativa japonica paddy fields, identifying the microorganisms contributing to rice growth adaptability. The combined approach revealed the taxonomic composition and functional potential of the bacterial community in the paddy field agroecosystem.
Short‐term effects of mineral and combined mineral‐organic fertilization in soil microbial communities
A one-year fertilization trial in a Qinghai-Tibet Plateau greenhouse found that both mineral and combined mineral-organic fertilization increased bacterial richness and decreased fungal diversity compared to unfertilized soil, with available phosphorus as the primary driver of microbial community structure changes.
Addition of High-Quality Plant Residue Alters Microbial Keystone Taxa and Network Complexity and Increases Soil Phosphorus (P) Availability
Researchers found that adding high-quality plant residues like pumpkin stems to acidic soil boosted available phosphorus by nearly 64 percent and stimulated beneficial microbial communities. The improvement was linked to increased populations of key bacterial species and stronger cooperative interactions among soil microbes. The study suggests that the type and quality of plant material added to soil plays a critical role in shaping microbial networks that drive nutrient cycling.
Phosphorus fertiliser application mitigates the negative effects of microplastic on soil microbes and rice growth
Researchers found that adding phosphorus fertilizer to soil contaminated with microplastics helped counteract the negative effects of the plastics on rice growth and soil microbial communities. The microplastics alone disrupted bacterial interactions and suppressed plant development, but fertilizer application restored much of the lost productivity. The study offers practical guidance for managing agricultural soils in areas affected by microplastic pollution.
