摘要：
The present invention relates to the use of diureides of dicarboxylic acids of the formula I in which R is hydrogen or SO2O⊖M⊕, M⊕ is lithium, sodium, potassium, cesium, ammonium, copper, silver, 0.5 iron, 0.5 calcium, 0.5 magnesium, 0.5 manganese, 0.5 zinc or 0.5 cobalt and X is a saturated or monounsaturated, straight-chain or branched C1- to C8-alkyl which may be interrupted by oxygen or NH and which may have attached to it C1- to C4-alkoxy, hydroxyl and/or amino groups, as slow-release fertilizers and to novel diureides of the formula Ia in which R is SO2O⊖M⊕, M⊕ is lithium, sodium, potassium, cesium, ammonium, copper, silver, 0.5 iron, 0.5 calcium, 0.5 magnesium, 0.5 manganese, 0.5 zinc or 0.5 cobalt and n is 1, 2, 3 or 4, and a process for their preparation.
