An in-vitro experiment to evaluate total nitrogen content of soil of tea plantation area included with indigenous and exogenous AzotoÂbacter sp have been conducted in the Biology and Soil Biotechnology Laboratory, PadjaÂdjaran University. A completely randomized design with 11 treatments and three repliÂcations was used. The treatments were: A (neÂgative control); B (positive control); C (A. Kedelai II); D (A. vinelandii); E (A. N.D.9.3); F (A. Padi); G (VI-1); H (II-1); I (V-2); J (I-1); and K (III-2). Size of microbe inoculated popuÂlation for each treatment was 1,2 x 1011 CFU/ml. One percent dose was used for steÂrilized soil originated from the tea plantation area. After five days of incubation period reÂvealed that II-1 Azotobacter sp produced very significantly different in total nitrogen proÂduction than the other Azotobacter sp, i.e. 0,8532%. Orthogonal comparisons indicated that indigenous Azotobacter sp had the capacity of nitrogen fixation 7,67% higher than that the capacity of nitrogen fixation of exogenous Azotobacter sp for growth on Andisol soil of tea plantation area with pH of 4,5-5,6. Although, Azotobacter sp is very rarely found in soil with low pH (high acidity), this phenomena indiÂcating that an active biofertilizer of indigenous Azotobacter sp is present in tea plantation area.

Tea was planting an upland area with Andisol as the dominant soil ordo. Andisol has a special characteristic i.e. low soil pH and it has more mineral that causing low of soil phos-phate soluble, especially for tea plants, there-fore the rule of solubilizing phosphate bacteria will be needed. Laboratory scale experiments were conducted to study the capability activities of some solubilizing phosphate bacterias name-ly Pseudomonas cepaceae, P. malei, Bacillus mycoides, and B. subtilis. The experiment was arranged in Completely Randomized Design with six treatments and four replications. The result on statistical analysis shown that there were no significant differences in increasing of the soil phosphate soluble. Nevertheless, the treatment D (Bacillus mycoides) produced the highest soil phosphate soluble. The capability of bacteria to increase soil phosphate soluble was depended on its habitat, especially soil pH. Even all of the isolates were the superior solubilizing phosphate bacterias in agricultural food plants with neutral soil pH, but they have not significantly different on Andisol. There-fore, the using of indigenous isolates on tea plant areas was suggested.
