Abstract:
The aim of this study was to investigate the effects of different incubation times and increasing levels of vermicompost applications on the nutrients contents (total N, available P, exchangeable K, ca and Mg, available Fe, Mn, Zn and Cu) of soils. For this purpose, vermicompost were applied at 4 doses (0, 50, 100 and 200 kg da-1), and left to the incubation for 0, 30 and 60 days. This study was carried out in 3 replications according to randomized block experiment design in greenhouse conditions. Soil samples were taken at the end of incubation times, and analyzed for total N, available P, exchangeable K, Ca and Mg, available Fe, Mn, Zn and Cu. While the effects of different incubation times on the total N, available P, exchangeable K, Ca, available Zn, Fe, Mn and Cu contents of the soils were statistically significant at 0.1%; the exchangeable Mg content of soils was statistically insignificant. As a result of the experiment; depending on the prolongation of the incubation times (towards the 60th day), the exchangeable K, Ca and available Mn contents of soils may be reduced; the available P, Zn, Fe and Cu contents of the soils decreased to 30th day but increased on the 60th day; It was determined that the total N content of the soils increased until 30th day due to prolongation of incubation times but decreased at 60th day. It was determined that the effects of increasing vermicompost applications were found to be statistically significant at 0.1% on the total N, availble P and exchangeable K, 1% on the Zn and Mn contents, and 5% on the changeable Ca content, but not statistically significant on exchangeable Mg, available Fe and Cu contents of soils. Depending on increasing vermicompost applications, it was determined that the available, P, Zn, Mn and exchangeable Mg contents of the soils increased, and the contents of total N and exchangeable Ca decreased. As a result, depending on the different incubation times and increased vermicompost applications, the nutrients contents of the soils were different from each other. The contents of the plant nutrients were generally decreased with the prolongation of the incubation times, and increased with increasing vermicompost applications
