Jurnal ini memuat hasil This study aims to measure the potential nitrfiikasi of nitrification, denitrification, and DNRA and measure the abundance of bacteria in the rubber plantations in Jambi.

Ex situ simulation of this biogeochemical cycle indicate a duration of 13 – 21 days tocomplete the nitrification process. Information For Readers For Authors.

Results of the study showed that the numberof nitrifying bacteria is highest at connecting channel between floodplain lakes L. Nitrification is oxidation of ammonium to nitrate. Water samplings are conducted for three times inthose were in dry season June ,transitional August and the rainy Sept. The lowest potential rate was DNRA. The effect of glyphosate application on the activity of nitrification decreases when weed density increases. In observation of cell morphology and gram staining of isolates nitrifying bacteria isolates derived nitrifying 6 were classified as gram positive and 3 were classifield as gram negative.

From the results of isolation at 3 sampling locations obtained the average number of bacteria of each media, which is to the bacteria Nitrosomonassp.

The finding indicated that 5 genus of nitrifying bacteria had different level of maturity in peat soil. The experiments were carried out using completely randomized design, with four level of glyphosate concentration, 0, 3. As for the bacteria Nitrobacter sp. The results indicate that the effect of glyphosate on nitrification activity depend on the concentration of glyphosate application and weed density.

The ammonium sulphate fertilizer equivalent to kg per hectare were given to the experimental area one week before glyphosate application treatment. Metadata Show full item record. More information and software credits. The purpose of this research to isolate the nitrifying bacteria in the rhizosphere of local aromatic rice that grown conventionally in the Tana Toraja.

The sampel was taken at wildlife sanctuary of Ambawang mountain Kubu Raya district. Collections UT – Biology []. Research on the isolation of nitrifying bacteria in the rhizosphere of local aromatic rice Oryza sativa L. Denitrification and disimilatory nitrate reduction to ammonium DNRA is the process of anaerobic nitrate reduction.

This study was aimed to reveal feature of nitrification process in several floodplainhabitat types of Lake Loa Kang Fishery Reserve LLFR system with emphasize on thespatial distribution pattern of nitrifying bacteria. Isolation of bacteria was conducted by serial dilution up to by using a specific medium nitrification.

The proses of isolation was conducted by pour plate method that applying spesific media of nitrification and total plate account was used to calculate the density of bacteria. This element is an essential nutrient for plant growth. Some features of this site may not work without it.

The purpose of this study is to investigate character nitrifikwsi density of nitrifying bacteria at maturity level of peat soil. Theduration of nitrification process in LLFR suspected to be influenced by the number ofbacteria, organic material and season. Nitrification is one key ofmicrobiological process of nitrogen cycle in inland water.

The ammonium and nitrate availability measurements have been done before glyphosate application and at 7th, 14th and 28th days after. User Username Password Remember me. Keywords nitrifying bacteria, density, maturity level of peat soil.

Nitrification bacteria obviously overcome the effect ofglyphosate.
