Effect of Brick kiln's emission on Plant growth promoting soil bacteria

Akanksha & Kapildev Prasad

ABSTRACT:

Plant growth promoting soil bacteria were isolated from the soil near brick kiln and half km away from brick kiln by culturing on Ashby's medium. Their phosphate solubilizing capacity, potassium solubilizing capacity and HCN production activity were measured. Soil was collected from 50m away, 100m away and 150m away from brick kiln at each side i.e. North, South, East and West. The CFU/gm value of plant growth promoting soil bacteria at a distance of 50m, 100m and 150m away from brick kiln was very poor in comparison to the CFU/gm value of these bacteria half km away from brick kiln. The lowest value of CFU/gm was observed in the soil 100m away from brick kiln in its East side (15X10⁶) followed by 150m away (20X10⁶) in East side and at 50m away the CFU/gm value was (22X10⁶) in its East side while CFU/gm value of these bacteria in soil at a distance of half km away was measured as 32X10⁶ CFU/gm.
