Abstract:

In this study, the effects of Micrococcus luteus vaccination, made along with stone phosphate and TSP (triple super phosphate) fertilizer, on some absorbable P and NO3-N contents of the soil and on the biological properties of the soil (soil inhalation, microbial biomass C, dehydrogenase, phosphate activity). Considering the phosphor fixation capacity of the soil used as the experimental material and the absorbable P content in the soil, the test subjects have been created according to the absorption of 0, 25, 50, 75 and 100 percent of the phosphorus to be given to the soil in the special grain plant, respectively, from stone phosphate and TSP, and the non-vaccination and vaccination of the soil with Micrococcus luteus AR-72. According to the test subjects, the shells created were left in incubation for 120 days at 25 0C. During the incubation trial, four land samples were made in 30 days periods. P and NO3-N can be taken in the soil samples in each incubation period with soil inhalation (TS), microbial biomass C (MBC), dehydrogenase (DHA) and alkaline phosphatease (FA) activity values. According to the results obtained, Micrococcus luteus AR-72, made together with both stone phosphate and TSP, has been found that soil increases the absorbable P and NO3-N content more than the non-vaccination applications. However, the vaccination with TSP fertilizer has been found to increase the content of P and NO3-N that can be taken according to the stone phosphate. Furthermore, the Micrococcus luteus AR-72 vaccination made with both stone phosphate and TSP has increased the MBC, TS, DHA and FA content of the soil according to the non-vaccination applications, the vaccination made with stone phosphate fertilizer has increased the MBC, TS and DHA content of the soil according to the TSP but the FA values have been found higher in the vaccination made with TSP fertilizer.
