Morphology and Physico-Chemical Properties of Upland Area of Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj

Abstract

The study evaluate the morphology, physico - chemical characteristics as well as the nutrient status of upland
soils, located in Sam Higginbottom University of Agriculture Technology & Sciences (SHUATS) area of prayagraj.
Profile depth of 1m, with 20cm interval for 5 different samples are examined for their morphology, physical and chemical
properties. A total numbers of 5 samples were collected from different depth at 20cm interval. All field and laboratory
analyses were done following standard procedures. The results indicate that the nutrient status of the upland soils in the
area were moderate. The nutrient status recorded a neutral pH of 7.03 in the study area, with 0.39dSm-1
electrical
conductivity, the available nitrogen recorded was low with 139.54 kg ha-1
, organic carbon recorded a value of 0.9%, the
organic matter also recorded a value of 1.6%.The soil has no carbonate threat with a recorded value of 0.50%.The
physical properties of the soil give a bulk density of 1.30Mgm-3
,particle density of 3.0 Mgm-3
, with total porosity of
56.80%,and a solid phase of 43.6%.The soil particle size show a textural class of sandy clay loam of 65.2% sand, 26.6%
clay, 8.2% silt, with angular to sub angular blocky structure, the morphology of the study area show a yellowish brown to
dark yellowish brown color, with clear and smooth horizon boundaries ,and a little abrupt distinction. The soil shows a
friable consistency at the surface and a moderately hard consistency at the subsurface horizons.
