Amidase is an enzyme that catalyzes the hydrolysis of aliphatic amides yielding ammonia and the corresponding carboxylic acids. Amidase activity was recently detected in soils; therefore, amides can be thought of as potential nitrogen fertilizers. Urea, which is an amide, is hydrolyzed by urease, and in this study, it was used as a standard fertilizer along with ammonium nitrate. Few other amides had already tested as sources of nitrogen for plants. Formamide and oxamide were shown to serve this purpose successfully. The main obnective of this study was to assess the potential of some amides as nitrogen fertilizers by comparing the dry-matter yield and N recovery produced from soils treated with amide with those obtained with two coventional fertilizers, urea and ammonium nitrate, as sources of N for rygrass in pot experiment. The amides tested were formamide, acetamide, 2-cvanocetamide, glycinamide, oximide, and azodicarbonamide. An additional objective was to study the effect of these nitrogen sources on the uptake of phosphorus and patassium by plants. |
