High phosphate retention in andisol soils causes low P-Availability in the soil. Nutrient phosphate has a very important role in plant growth. Actinomycetes can be used to dissolve phosphates that are bound to the soil. This research aims to obtain Actinomycetes and tests their effect on increasing the availability of phosphate. This research was carried out in the Soil Biology Laboratory with 2 stages, namely: 1. Isolation and Purification and 2. Test potential of Actinomycetes on Pykovskaya media with several phosphate sources (Ca3(PO4)2; AlPO4 and FePO4). The results obtained showed that there were 17 Actinomycetes isolates isolated from andisol soil at various locations. Some Actinomycetes obtained have the ability to dissolve P-not available into P available on solid pykovskaya media with various phosphate sources (Ca3(PO4)2; AlPO4 and FePO4) but with different abilities.

Rhizobia fixed nitrogen from the air and supplied legume and effected to soil fertility. The research was conducted in May application of Rhizobia's isolate BGR 3 showed the infektively with root nodule amount criteria (124,00). The isolate Rhizobia's BGR 3 effectively increased N plant level and N absorption (3,80 %; 31,08mg/plant). Application of isolate Rhizobia was not able to increase the level of P plants and P plant uptake. The best interaction was shown (Plant height 85.00 cm, stem diameter 3.93 mm, root nodule 127.50, N level of 3.80%, N absorption 30.16 mg / plant) by treatment of BGR 3 and Lime 1 x Aldd.
