Effect of Different Doses of Sewage Sludge on Soil Health of Black Gram (Vigna mungo) Field in Allahabad Region of India

摘要

A field experiment was conducted on an alluvial soil to determine sewage sludge efficiency on the soil of Black Gram (Vigna mungo) field. Six treatment combinations (3 varieties × 2 sewage sludge doses) were applied to conduct this research. After harvesting of crop, soil samples were taken and brought into the laboratory for analysis of different soil parameters. pH of soil varies from 8.1-8.4. This shows the basic nature of sewage sludge. EC of the soil varies from 0.24-0.27 dSm~(-1). Organic carbon of the soil varies from 0.49-0.53 % due to increasing carbon content in sewage sludge. Due to improving electrical conductivity nitrogen and phosphorus were also increased. The potassium content of the soil varied from 155.39-166.67 kg/ha. Thus, the study reveals that, soil pH, electrical conductivity, organic carbon, nitrogen, phosphorus and potassium were inclining with increasing doses of sewage sludge.
