Abstract: PROBLEM TO BE SOLVED: To use a specific dicarboxylic acid diureide as a slow-acting fertilizer for nitrogenous fertilizers through combination with other commonly used fertilizers or additives so as to effect delayed release of a plurality of nutrients contained for crops and sustain the tolerance of crops to the fertilizers and the action of such fertilizers. SOLUTION: A dicarboxylic acid diureide shown by the formula [R is H or SO2OM+; M+ is Li, Na, K, CS, NH4, Cu, Ag, 0.5 Fe, 0.5Ca, 0.5Mg, 0.5Mn, 0.5Zn or 0.5Co; X is a straight-chain or branched 1-8C alkyl having one saturated or unsaturated group (pref. (CH2)n, n is 1-4) and, optionally, discontinued by O or NH, or having a 1-4C alkoxyhydroxy and/or amino group(s)] is uses as a slow-acting fertilizer. This compound of the formula is obtained, for example, by reacting the corresponding carboxylic acid diamide with chlorosulfonyl isocyanate at -20 to 20 deg.C followed by reaction with an aqueous solution of M2CO3 at -10 to 0 deg.C.

Abstract: Use of dicarboxylic acid diureides (I) as slow-release fertilizers is new. Use of dicarboxylic acid diureides of formula (I) as slow-release fertilizers is new. R = hydrogen or SO2O M ; M = equivalent of lithium, sodium, potassium, ammonium, copper, silver, iron, calcium, magnesium, manganese, zinc or cobalt; X = 1-8C alkyl, saturated or with one unsaturated bond, optionally interrupted by oxygen or NH, and optionally substituted by 1-4C alkoxy, hydroxy and/or amino An Independent claim is also included for the production of (Ia).

Abstract: Composition comprises at least two different (thio)phosphoric acidtriamide (I). Composition comprises at least two different (thio) phosphoric acidtriamide (I) of formula (R 1R 2N-P(X)(NH 2) 2). Either R 1, R 2H, 1-10C-alkyl-, 3-10C-cycloalkyl-, 6-10C-aryl- or dialkylaminocarbonyl; or N(R 1+R 2) : 5-6 membered optionally saturated heterocycle, optionally containing 1 or 2 heteroatoms that are replaced by N, O or S; and X : O or S. Independent claims are included for: (1) the preparation of the composition comprising mixing at least two (thio)phosphoricacidtriamide together or transferring thiophosphorylchloride with a mixture of at least two different primary- or secondary amine and subsequently with ammonia; and (2) a urea containing fertilizer comprising the composition.
