摘要:
The invention relates to phosphate compounds obtained according to a method comprising reaction of a source of insoluble phosphate with an organic source, principally of vegetable origin, optionally in the presence of a mineral acid or an organic acid, said organic source having at least 10% of complexing functional groups.The compounds of the invention are useful for preparing fertilizer.

摘要:
Novel metal complexes useful in the area of agriculture, notably as agents for treating metal deficiency. The novel metal complexes comprise at least one metal selected from the metal trace elements essential for the development of plants, at least one first ligand selected from the lignosulfonates, and derivatives thereof, and at least one second ligand selected from the multidentate organic ligands.
