PH, EC and OC Status of Chittoor District Soils of Andhra Pradesh
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 4
Abstract
Analysis of 576 geo-referenced surface soil samples collected using stratified random sampling techniques from 64 mandals of Chittoor district of Andhra Pradesh. The pH of the soils was found to be in the range of 4.5 to 8.9 and majority of them (53%) were alkaline in nature. The EC of the district soils was normal and was in the range of 0.10 and 1.66 dSm-1. Fifty five percent of soils analyzed from Chittoor district were found to be medium in organic carbon content (0.5 to 0.75%) and 43% registered low organic carbon content. The nutrient index rating for OC, therefore, was found to be medium (1.78). All the thematic maps related to studying PH, EC and OC were prepared in a GIS environment and presented
