Abstract
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, 1,3-diamino-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
(PO43-) 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.
