These comparisons suggest that Fe and Al ions would first react with P forming FeP[O.sub.4]-2[H.sub.2]O and Al P[O.sub.4] x 2[H.sub.2]O on the surface of Fe-Al-oxides, instead of the chelation of Fe and Al ions with maleic acid and itaconic acid when fertiliser P mixed with the copolymer is applied to the acid soils.

Maleic acid (cis-2-butene-l, 4-dioic acid, Lide, 2004) and its corresponding methyl ester, dimethyl maleate (DMME) in which the alkene double bond is in conjugation with a carboxyl group, undergo isomerization on treatment with catalytic amounts of aqueous bromine or [[Br.sub.2]/[CCl.sub.4]] under UV light to form the thermodynamically more stable trans isomer.
