| Abstract: | Potential of nitrification in the three soil profiles of China was investigated. The data indicated that potential of soil nitrification was significantly correlated with soil pH (r=0 750 ** ), Soil organic matter content was correlated with potential of soil nitrification also, but it did not reach the significant level. It can be drawn that soil pH and soil organic matter content were the main factors to affect soil nitrification activity. It was presumed that the possibility of nitogen fertilizer loss by leaching and nitrification denitrification in the three soils. |
