The result of the experiment revealed that the soil available nitrate decreased at the first four weeks of the incubation and increased from weeks 5 to 7. Soil pH did not change at the first 2 weeks of the incubation, however, raised for the rest of the incubation. At the end of the incubation, the application of vermicompost at the rate of 12.5 g kg-1 supplemented with 100% LOF exhibited the greatest soil available nitrate. Also, the same treatment combination had the highest soil total nitrogen (TSN) and soil pH. This finding is significantly managed for nitrogen fertilization using vermicompost in Inceptisols.
