Objective: The objective of this study is to determine the physicochemical properties and nutrient content of agricultural soils at various stations such as black soil from Kalroad Palli village (Chandragiri mandal), red soil from Ramapuram village (Ramachandrapuram Mandal), and clay from Yerpedu village (Yerpedu Mandal) of Chittoor district.
Method:The physicochemical parameters such as pH was measured using pH meter (Thermo Scientific); electrical conductivity (EC) was measured by conductivity meter (CM180 Elico Technologies); organic carbon (OC) was determined by Fourier-transform infrared (Agilent technologies 630) and with ultraviolet (UV) spectrophotometer (Agilent technologies Cary UV 60); nitrogen (N2) was estimated by Kjeldahl method; potassium (K), sodium (Na), and calcium (Ca) were estimated using flame photometer (Elico Technologies CL/361); and magnesium (Mg) was estimated by titrimetric method.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
