Effect of grey water application on physicochemical properties of tomato growing soil

Abstract

A field study was conducted on “Effect of grey water application on physicochemical properties of tomato growing soil” during Rabi season of 2017 at RPCAU, Pusa Farm. Soil samples (0-15cm) were investigated for physical and chemical properties, viz., bulk density, texture, porosity, pH, EC, organic carbon (OC), available nitrogen, phosphorous, potassium, sulphur, boron. Use of grey water significantly improves the soil properties like bulk density, pH, organic carbon, nitrogen, phosphorous, potassium, boron in soil. The concentration of nutrient like N, P, K and b was recorded highest viz. 389.0 kg ha-1, 182.9 kg ha-1, 176.7 kg ha-1 and 0.46 mg kg-1 respectively in 100% grey water applied soil. All chemical parameters and nutrient contents were found higher in grey water than ground water treated soil. Application of gray water can be a good choice for plant nutrient enrichment in farmland.
