Nitrification inhibitors are characterised in that they contain as active substances 1H-1,2,4-triazole or substituted 1H-1,2-4-triazole, its salts or metallic complexes, and at least another compound such as a substituted pyrazole, its salts or metallic complexes, dicyanodiamide, guanylthiourea, thiourea, ammonium thiosulfate, ammonium thiocyanate. These agents have considerable synergistic effects and, compared with the individual compounds, are more effective and economic, and they may be used in reduced amounts. Se describen medios para la inhibicion de la nitrificacion que se caracterizan porque contienen como componentes de sustancias activas iH-1,2,4-triazol o un 1H-1,2,4-triazol sustituido o sus sales o complejos metálicos y, como mínimo, otro compuesto como un pirazol sustituido, sus sales o complejos metálicos, dicianodiamida, guanilotiourea, tiourea, tiosulfato amonico, rodanuro amonico. Estos medios segun el invento presentan respecto a los compuestos individuales considerables efectos sinérgicos, y resultan por ello ventajosos con vistas a aumentar la eficiencia, reducir la cantidad utilizada y a su economía.
