Degradation of Adjacent Agricultural Land with Leachates of Packaged and Waste Food Dumped Near It

Abstract

Physico chemical parameters of dumped food leachates at dump site adjacent agricultural soil at Chapra city, Bihar were investigated for possible pollution impacts. Soil samples were collected in three replicates from two sampling points within the dump site and for control soil samples were collected about 200m. Standard methods were used to determine the following parameters. The pH of leachate affected soil ranged between 7.3 to 7.5 while in control it was 7.6 to 7.8. The electric conductivity 3.6 to 3.82 while in control 1.89 to 1.91, sodium % 5.62 to 7.86 in LAS and 4.25 to 4.68 in control, organic matter g/kg = 16.7 to 20.5 in LAS and 14.30 to 17.64 in control. Calcium carbonates (g/kg) 288.6 to 305.4 in LAS and 264.6 to 280.2 in control. Total nitrogen % in LAS 0.36 to 0.42% and 0.2 to 0.24 in control available phosphorous in mg/kg in LAS. 14.5 to 11.6 mg/kg and 8.62 and 9.15 mg/kg in control. Available potassium in LAS required between 432.4 to 451.6 mg/kg and 332.3 to 362.7 mg/kg in control amount of calcium 14.2 to 16.5 Cmol/kg in LAS and 12.2 to 12.8 Cmol/kg in control. The magnesium contents ranged between 4.2 to 4.6 Cmol/kg in LAS and 3.60 to 3.90 C mol/kg in control.
