Dissolved organic matter (DOM) is involved in numerous biogeochemical processes, and understanding the ecological succession of DOM crucial for predicting its response to farming (e.g., fertilization) practices. Although plentiful studies have examined how fertilization practice affects content soil DOM, it remains unknown long-term drives over temporal scales. Here, we investigated paddy rice rhizosphere soils subjected different treatments (CK: no fertilization; NPK: inorganic OM: along with plant growth. Our results demonstrated that significantly promoted molecular chemodiversity but weakened correlation between composition development. Time-decay analysis indicated had a shorter halving time under CK treatment (94.7 days), compared NPK (337.4 days) OM (223.8 treatments, reflecting lower turnover rate fertilization. Moreover, development affected assembly process only CK, not treatments. Taken together, our fertilization, especially greatly weakens rhizosphere, which has profound implication complex plant-DOM interactions.

Phototrophic Biofilms Transform Soil-Dissolved Organic Matter Similarly Despite Compositional and Environmental Differences

Dissolved organic matter (DOM) is the most reactive pool of carbon in soil and one important components global cycle. Phototrophic biofilms growing at soil–water interface periodically flooding–drying soils like paddy fields consume produce DOM during their growth decomposition. However, effects phototrophic on remain poorly understood these settings. Here, we found that transformed similarly despite differences types initial compositions, with stronger molecular composition than nutrient contents. Specifically, biofilms, especially those genera belonging to Proteobacteria Cyanobacteria, increased abundance labile compounds richness formulae, while biofilm decomposition decreased relative components. After a cycle, universally drove accumulation persistent soil. Our results revealed how shape changes level provide reference for using increase bioactivity fertility agricultural
