title: [Effect of fertilizers on the number of bacteria involved in the turnover of nitrogen in pond water of the Astrakhan Region].
abstract: The type of intensification affects the distribution of bacteria involved in turnover of nitrogen in pond water. Green fertilizers (reed) stimulate the number of nitrogen-fixing bacteria, and the number and activity of nitrifying bacteria, to a higher degree than nitrogen and phosphorus fertilizers. Reed is recommended as the main means for intensification of spawning ponds of the Astrakhan Region.
