Chemical Analysis of an agricultural land for different parameters before and after Diwali in the village of Bihar

Abstract

Scenario of celebrating Diwali has changed now a day. These days house is decorated by coloured electric bulbs and people of different age group gather near an open field and explode different kinds of fire cracker for several hours. The burning of gunpowder along with different compounds used for colour and light, no doubt causes pollution of the ambient airs, rather the residues comes to the ground and also causes alterations I the agricultural soil. To evaluate the impacts of these residues soil samples were analyzed for different parameters before and after the festival. Parameters observed in the present study were, pH, organic matter, electrical conductivity, nitrogen contents, exchangeable sodium, phosphorous, calcium, magnesium, chloride, phosphate, iron etc. During the work it was noted that the pH soil was reduced to 7.6 after the festival from 7.2. However, the electrical conductivity was increased from 0.285 µs cm2. There were slight variations in the organic carbon which became 2.70% after the festival than 2.56 that was before the festival. Sodium content increased to 29.74 mg/kg from 26.32 mg/kg. This was also noted in case of potassium, which become 18.48 mg/kg from 16.64 mg/kg. Likewise calcium from 34.52 mg/kg to 37.28 mg/kg magnesium from 11.38 to 13.6, iron from 126.24 mg/kg to 130.65 mg/kg respectively. Similarly, chloride from 280.0 mg/kg to 284.0 mg/kg, nitrate from 124.0 mg/kg and sulfate from 130.0 to 133.0 mg/kg respectively. It has been mentioned that above chemical are components of different kinds of five crackers and after burning their residues might have fallen down to the soil.
