Geometrical Assessment of Soil calcareousness: Acase study from Telangana State, India

Abstract

The accretion and hauling of carbonates are used to identify, and interpret the soil formation processes in the soil profile. Predominantly, these soils types comprise over one-third of the world’s land surface area. Generally, Calcareous soils are identified by the presence of calcium carbonate (CaCO3) in the parent material. When the soil samples are treated with dilute Hydrochloric acid, an accumulation of lime through the fizzing occurs, and releases carbon dioxide. The released carbon dioxide gas concentration indicates the level of carbonates present in the soil. In this study, the thematic data integration of calcareous soil values, and soil types is done using Remote sensing and GIS tools to get the action plan maps by Arc GIS 10.3 software. From this, it is identified that almost 50% of Gopannapalle village is suffering from 35-60% calcareous, followed by 30% of the study area with 15-35% slightly calcareous and 70% of Anekunta village is suffering from 35-60% calcareous, followed by 20% of the study area with 15-35% somewhat calcareous. Based on the calcareous maps, it is recommended that the soil infertility and soil pH can reduce by improving proper fertilizer management and organic manure applications to increase its nutrient value.
