Abstract: 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.

Abstract: It consists of using a precursor compound of cyclic AMP, or an inhibitor compound of the enzymes of the Phosphodiesterases family, or a stimulating compound of the enzymes of the Adenyl-Cyclase family, or an agonist compound of the ?-adrenergic receptors to which arachidonic acid or a prostaglandin is added. The composition object of the invention can be presented mixed with mineral fertilizers (such as amonic nitrate, monopotassium phosphate, etc.), with phytoregulators (such as cytoquinines, auxines, giberelines, polyamines, n-ethanolamines, sugars . . . ) or with any type of phytosanitary product (such as fungicides, herbicides etc.). The composition object of the invention can be formulated with tensoactive agents (such as Tween 80), moistening agents etc. The composition object of the invention can be applied to any species of plant and at any point in its life cycle.
