Abstract

A phosphorus fractionation study was conducted in the surface soil of Azamgarh district, 2022-2024 U.P. by collection of surfaces (0-15 cm) soil samples from five village of each block of district (110 village) and prepare composite sample of each village. Analyses were conducted in the laboratory of department of Agricultural Chemistry and Soil Science, Shri Murali Manohar Town P.G. College, Ballia followed by standard procedures reported by different authors. Soils of every village were light textured soils, neutral to slight alkaline in nature. The distribution of the different phosphorus fraction in surface soils were viz. Saloid-P ranged from 23.00 to 53.87 ppm, Al-P 11.30 to 19.87 ppm, Fe-P 15.50 to 37.10 ppm the Reductant Soluble-P 15.75 to 44.55 ppm, Occluded-P 13.13 to 30.56 ppm, Ca-P 90.20 to124.25 ppm, Organic-P 82.25 to 152.01 ppm with Total Phosphorus 369.30 to 481.05 ppm respectively in different village surface soils. Among the different fraction of P, total-P, Organic-P, Ca-P were observed in greater concentration while Al-P, Fe-P, Occl-P, RS-P, ESS-P were observed comparatively in small concentration.
