- Abstract:
-
The ammonia production by bacteria in soil not only could influence the recycle of nitrogen source in soil, but also could be used to improve the acidified soil. In this review article, the biological characteristics and molecular regulation mechanism of ammonia producing pathway by bacteria in soil, the factors influence the urease activity in soil, environmental factors, urea sources, and research progress of microbial interaction will be reviewed. It points out that urease activity in soil is one of the most important indexes to test quality and fertility of soil. The urease activity has an intimate connection with nitrogen fixation, soil reclamation and other ammonia production metabolism. In one word, the urease activity is of great significance to the soil nitrogen fertility evaluation and crop production.
