Sewage sludge (SS), a byproduct of treated wastewater by sewage treatment plants (STPs) are rich in organic C, and other macro –micro nutrients, which if properly managed can be used to improve organic fertility in intensively cropped degraded soil. A field experiment was conducted to examine the role of sewage sludge from different sewage treatment plants with various doses of phosphorus on physicochemical and macronutrient in soil depth under (Vignaradiata L.). Sandy loam soil, during Zaid seasons of 2017at the Nursery of Forestry, Department of Environmental Sciences & NRM in SHUATS, Prayagraj.Nineteen treatments were employed using three different areas STPs sewage sludge (SS) they are Naini STPs (A1), Rajapur STPs (A2) and Pritamnagar STPs (A3) of two different doses of SS (10 t ha-1 and 15 t ha-1) with two-level of phosphorus (60kg ha-1 and 30kg ha-1) to find the effect and accumulation of macronutrient after application of SSin soil 0-15 & 15-30 cm depths. The results showed a positive effect of sewage sludge on physical and chemical parameters on treated soil. BD (g cm-3) and Solid space (%) was significantly decreased and highest data was recorded in particle density(g cm-3), pore space %, EC, OC% in both soil 0-15 & 15-30 cm depth in treatment T3 (Naini 15 t ha-1) after application of sewage sludge as compared to control T1.pH was a basic parameter of soil it showed slightly acidic at higher concentration of SS in Treatment T3 as compare to T9(Rajapur 15 tha-1 ) and T15(Pritamnagar 15 t ha-1 ). The study revealed that quality of Pritamnagar SS showed positive results compare to other SS of different STP because it had low pH with higher amount of NPK which enhance the soil health and the latest technology was used for treatment process of waste. Lower concentration of SS application was beneficial for soil productivity and agriculture for a short period of time.
