Evaluation of multi-functional organoaminophosphonic acid complexes as next-generation fertilizers, herbicides and crop protection agents

Résumé fourni par la source

Innovative inputs that increase crop output while reducing environmental damage are required by modern agricultural chemistry.Three new organoaminophosphonic acid ligands-1,3-diamino isobutene-1,1,3,3-tetraphosphonic acid, 1,3diamino-2,2-dimethyl propane-1,1,3,3-tetraphosphonic acid, and 1-amino, 1-phenyl, 2-carboxy ethane phosphonic acid-as well as their transition metal complexes are thoroughly evaluated in this work.These polydentate chelating compounds exhibit dual-action agronomic effectiveness by using their distinct structural topologies.High vascular mobility is confirmed by foliar absorption and phloem-trapping kinetics, which promote systemic protection throughout the plant matrix.Importantly, rhizosphere biodegradation modeling shows that the carbon-phosphorus (C-P) lyase route causes these compounds to undergo fast to regulated microbial breakage.This mechanism releases secondary orthophosphate (PO4 3-) and bioavailable nitrogen (NH4 + , NO3 ¯) directly to the crop while breaking down the ligands into non-toxic components.These aminophosphonates have a low groundwater leaching footprint and no buildup of hazardous intermediates, in contrast to persistent synthetic chelates (like EDTA).This technological profile demonstrates that organoaminophosphonic compounds are practical, highly effective, and environmentally sustainable substitutes for traditional agrochemical regimes.
