Delineation of soil fertility and nutrient index of Sohaon block soil of Ballia district, U.P

Abstract

A experiment was conducted by collected surface soil samples from 31 villages wise composite surface soil sample (0-15 cm) from 31 villages of Sohaon Block (Pipara Kala, Sohaon, Nasirpur Khan, Narahi, Govindpur Khas, Sobantha, Sikandarpur, Senduriya, Basantpur Utari, Bairiya, Bharouli Khas, Ujiyar, Ramgarh Nasirpur Mutkal, Nasirpur Kalan, Narayanpur, Saraykota, Shrawanpur, Baghawana, Sarya, Salempur, Chaura, Kathariya, Amao, Kutubpur, Surahi, Lakhsmanpur, Medawrakala, Tutuwari, Daulatpur, Akhtiyarpur And Dularpur) of Ballia district. After analyses the soil pH was slightly alkaline, EC ranged from 1.032 to 1.044 dS/m, Bd values were varied from 1.5 to 1.6 Mgm-3 . The organic carbon content was ranged from 0.30 - to 0.8 %, WHC value was found that 44.5 to 46%, CaCO3 values were from 1.6 to 1.7 % , available nitrogen content was ranged from 103.48 to 307.32 kg ha-1 of different village, available phosphorus content was 8.13 to 17.92 kg ha-1 of different village, available potassium content was 268.8 to 358.4 kg ha-1 of different village, available sulphur content was 7.00 to 8.87 mg kg-1 , nutrient index of available nitrogen was 1.064, available phosphorus was 1.77 and for available potassium was 2.54 have been appeared.
