Abstract

A survey was conducted in the year 2019-20 in old Mahboobnagar and Nalgonda district of Telangana state to study the characters of calcareous soils, based on effervescence with dilute.HCL the samples were collected and were analysed for its characters. Majority of soils collected were medium to high in CaCO3 status. All the soils collected were alkaline to highly alkaline in reaction. Soils were low to medium in available nitrogen and phosphorus content. The average pH, N, P2O5, K2O value recorded in these soils were 8.49, 77.19 kg ha-1, 6.215 kg ha-1, 72.88 kg ha-1 respectively.  The main objective of the study is to know the properties of Calcareous soil and also to study the effect of calcium carbonate on the different properties of soil and therefore acorrelation study was conducted which reported that there is significant positive relationship is seen between CaCO3 content and pH and significant negative relationship is seen between CaCO3 content and available N and P2O5 in soil. No significant relationship is seen between CaCO3 content and EC and OC values.

Keywords: Calcareous soil, characterization, CaCO3 content, correlation
