Abstract: Soil is a wonderful gift of nature for living creatures. It supports crop growth. It is an important environmental factor, and has a close reciprocal relationship with the plants growing in it and the soil microbes that exist in it. The forest soil consists of high humus with variety of microbes. In this experiment forest area of Newasa was selected for evaluation of nutrient status and bacterial population. On the basis of density of grasses Iseilema prostratum L, Setaria pumila (Poir.) Roem. & Schult, Aristida hystrix L., Dactyloctenium aegyptium (L.) Willd, Fimbriristylis miliacea (L.) Vahl. were selected. 100 soil samples from different locations from rhizosphere of these monocots were collected and analyzed for soil nutrient status and nitrogen fixing bacterial population. It was recorded that, out of five plants, the rhizosphere soil of Setaria pumila L. showed maximum bacterial population (11700540.00). Available nitrogen (320 kg ha) and organic carbon (0.60 ) followed by Setaria pumila (Poir.) Roem. & Schult the bacterial population was (2558265.00), available nitrogen (203 Kg ha) and Organic Carbon (0.59 ). Other soil nutrients were also measured.
