Technology of the application of microbial preparations on ordinary chernozem soil in the zone of unstable moistening of the Central Ciscaucasia

Abstract

Studies were conducted in the zone of unstable moistening of the Central Ciscaucasia in the ordinary chernozem carbonate according to the scheme: 1. control 2. KBP-standard; 3. KBP – innovative; 4. PCM; 5. KMP-92. According to the traditional technology was carried out treatment of seeds before sowing and maize plants in the phase of 3-4 leaves and flowering, and on the proposed produce and processing of the soil. Revealed that the number of aerobic nitrogen-fixing bacteria on control in phase 3-4 sheet amounted to 21.1 thousand CFU/1 g, and in the flowering stage 76.3 thousand CFU/1 g and increased with the application of KBP-book standard respectively 2.2 and 1.7 times, KBP – innovative 1.9 and 1.6 times, PCM 2.1 and 1.4 times and the PCM-92 – 1.7 and 1.4 times. The lowest values have on the phase of wax ripeness. The number of ammonifying control in the phase of 3-4 leaves was 55 million CFU/1 g. and has increased as a result of the application of biopreparations in 1,4-1,6 times. In the flowering stage, the number of ammonifying control increased to 259 million CFU/1 g and increased by different versions from 1.6 to 1.7 times. Similar changes can be traced in the number of nitrifying microorganisms. The yield of corn for grain was lowest on control (of 4.07 t/ha), increased more than conventional technology, the embodiment with the use of KBP-S 24.1 %, and the proposed technology with the use of KMP-92 - 31.4%.
