The inhibitory effects of twelve metallic cations on urease activity in three soil types were evaluated. Four of these metals Cu +2 , Fe +3 , Al +3 and Co +2 in their sulphate forms were tested for retarding the urea hydrolysis in soils. They reduced the accumulation of NH 4 ‐N, nitrite and gaseous losses of ammonia between 35 and 50%.
