Abstract The integration of nanotechnology in agriculture offers a transformative approach to improving crop yields, resource efficiency, and ecological sustainability. This review highlights the application functional NM, such as nano-formulated agrochemicals, nanosensors, slow-release fertilizers, which enhance effectiveness fertilizers pesticides while minimizing environmental impacts. By leveraging unique properties agricultural practices can achieve better nutrient absorption, reduced chemical runoff, improved water conservation. Innovations like nano-priming seed germination drought resilience, nanosensors enable precise monitoring soil health. Despite promising commercial potential, significant challenges persist regarding safety, impact, regulatory frameworks for nanomaterial use. emphasizes need comprehensive safety assessments standardized risk evaluation protocols ensure responsible implementation agriculture.

ABSTRACT Polyurea emerges as a promising material for acid nanofiltration membranes due to its high hydrogen‐bonding capacity and low electron density from carbonyl groups. However, conventional polyurea‐based composite suffer limited separation performance stability insufficient hydrophilicity conjugated structures. In this study, novel monomer, 3,5‐diisocyanate benzoyl chloride, was synthesized employed the organic‐phase precursor in interfacial polymerization fabricate thin‐film (TFC) with polyurea‐amide active layers. During polymerization, acyl chloride groups undergo partial hydrolysis, introducing carboxylate anions into layer. The NF membrane shows over 98.6% rejection of MgSO 4 at pH 7, water permeability can reach 3.41 L m −2 h −1 bar . Additionally, aqueous phase monomer 2,4‐diaminobenzenesulfonic incorporated construct fully aromatic layer, which strengthens intermolecular conjugation resistance. Comparative analysis demonstrated that outperform traditional (prepared via toluene diisocyanate fatty amines) stability: after soaking 20 wt% H 2 SO 100 days, remained nearly unchanged. This study establishes molecular design strategy integrating hydrophilic functionalization structures address critical limitations polyurea membranes, offering pathway toward robust systems acid‐resistant applications.
