Abstract
Soil reaction (pH) is important property soil for crop productions. Many chemicals as ameliorates are required to make soil productive. In organic agriculture, bio-ameliorates are prerequisite. Rhizobia are acid producers and Bradyrhizobia are alkali producers. Rhizobia and Bradyrhizobia are used as ameliorate to study their impact on soil reaction (pH) in laboratory conditions for 21 days. It was observed that Rhizobia decreased soil pH and Bradyrhizobia increased soil pH during incubation.
Key words: Acid producers, alkali producers, brardyrhizobia, soil pH, rhizobia.
