The soils present near coal mines have the properties of high concentration of metallic minerals, elevated pH and shortage of essential nutrients for organism growth. But being rich in minerals they could provide a good energy source for plants. Soil near Coal mines of Neyveli was taken and subject to treatment with effective microorganisms that have fertilizing, antibiotic, iron solubilising, sulphur solubilising and photosynthesis helping activities. The microbes helpful in plant photosynthesis were isolated after studying their effect on chlorophyll content and photosynthesis rate by increasing their load on leaves after Humic acid spray. Microorganisms, mainly bacteria, with the above activities were isolated, characterised and cultured. The mines soil and a normal garden soil were treated with these microbes and their effects on plant growth (Abelmoscus esculentus and Trigonella foenum) was analysed by measuring the root length and shoot length of the plants. Simultaneously the soil parameters like pH and EC and chemical factors like NPK content were measured after the treatment. The mining soil showed significant positive result on plant growth and also an improvement in the physical and chemical properties after the microbial treatment.
