ABSTRACT



The object of the investigation were bacteria in the soil in diversified conditions of orchard irrigation and with the use of different methods of soil disease prevention. Samples for the estimation of the number of bacteria were taken in spring and autumn.

During the study the following results were obtained: the total number of bacteria in the replanted orchard was lower than in the soil where apple trees had not been cultivated before.

The irrigation did not increase of bacteria population in the soil, whereas the ammonium phosphate increased it. On the number of bacteria in the soil had influence also the application of the Alliette 80 WP and ammonia phosphate which decreased Azotobacter number in comparison with the control. The use of ammonia phosphate increased the number of Azospirillum in soil.

Key words: apple, replant soil, bacteria.
