Comparative study of sewage sludge from different stps and various doses of phosphorus on physicochemical and macro nutrient in soil depth under (Vigna radiata L.)

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. | Comparative study of sewage sludge from different stps and various doses of phosphorus on physicochemical and macro nutrient in soil depth under (Vigna radiata L.)
