Microalgal biomass offers a promising biofertilizer option due to its nutrient-rich composition, adaptability, and environmental benefits. This study evaluated the potential of microalgal-based biofertilizers-microalgal Chlorella biomass, de-oiled microalgal (DMB), de-aqueous extract (DAEMB)-in enhancing lettuce growth, soil nutrient dynamics, microbial community composition. Lettuce seedlings were cultivated with these biofertilizers, plant growth parameters, photosynthetic pigments, nitrogen uptake assessed. Soil incubation experiments further examined mineralization rates, while DNA sequencing analyzed shifts in rhizosphere communities. grown biofertilizers exhibited improved parameters compared controls, achieving 31.89% increase shoot length, 27.98% root 47.33% fresh weight. Chlorophyll total chlorophyll levels increased significantly all treatments, highest concentrations observed treatment. studies revealed that DMB DAEMB provided gradual release, rapid supply. Microbial analyses bacterial fungal diversity, abundance nitrogen-fixing nutrient-cycling taxa. Notably, diversity was enriched health reducing pathogenic fungi. These findings highlight biofertilizers' enhance fertility, health, sustainable resource use agriculture.

Food security, a crucial issue for the development of humankind, is often severely constrained by water scarcity. As globally recognized most advanced agricultural water-saving technology, drip irrigation under plastic mulch (DIPM) has played significant role in grain production. However, comprehensive review dual impacts this practice farmland remains lacking. This study conducted an exhaustive DIPM research from 1999 to 2023 and employed CiteSpace software perform co-occurrence clustering analysis keywords order reveal hotspots trends. The results show that attention technology increased annually reached peak 2022. China leads number publications field, reflecting its emphasis on technologies. critically discusses farmland. On positive side, can improve soil temperature moisture, enhance nutrient availability, promote absorption roots, increase crop growth rate yield while reducing evaporation nitrogen loss, suppressing weed growth, decreasing herbicide usage, lowering total greenhouse gas emissions. negative it will cause pollution residues, damage structure, have lead clogging systems, which costs energy consumption, hinder hamper salinization management, further reduce groundwater level. future requires optimization advancement. Such strategies as mechanized residual-mulch recovery, biodegradable substitution, aerated alternate are proposed address existing issues triggered DIPM. advocates active exploration farming management practices superior development. These could higher yields, water–nitrogen efficiency, lower environmental impact
