Results show that in biofertilizer treatment results in relatively low pH, which is optimum for solubilisation of bound
elements. Soil becomes alkaline after the treatment of chemical fertilizers. There is reduction of solubility of many nutrients
(Figure-a) and the soil treated with biofertilizer had high EC which is optimum for better plant growth (Figure-a).Results
shows that highest value of organic carbon in control followed by chemical fertilizer treated soil and least value in
biofertilizer treated soils. (Figure-b).Highest concentration of the nitrogen was found in control, followed by treated soil
with chemical fertilizer and lowest in treated soil with biofertilizer. The use of Chemical fertilizer has decreased the in
recent years, although it is a very good source of nitrogen. Application of biofertilizers decreases the nitrogen value in soil
(Figure-c). Chemical and biofertilizer treated soil results in optimum value of potassium which is less in control condition
(Figure-d).It was recorded that the chemical fertilizer treated soil shows highest concentration of phosphorus and
biofertilizers treated soil shows optimum concentration of phosphorus. On the other hand less concentration of phosphorous
was recorded in control condition. Excess availability of phosphorus in soils is often limited by fixation reactions, which
convert the ion into various insoluble forms and optimum availability of Phosphorus compounds act as energy currency
within the plants and involve in wide range of plant processes from permitting cell division to developing good root system.
Dutta et al,(2003)[9] reported that NPK played significant role in sustaining soil fertility and productivity of crop. Also a
higher positive effect on microbial biomass and hence soil health. Similar result were found by Chand et al, (2006)[10] and
Bokhtiar and Sakurai, (2005)[11].Figure-f shows that application of biofertilizer increases the level of micronutrients (Cu,
Zn, Fe and Mn) in soil and makes the soil healthy as compared to the chemical fertilizer.
