A team of scientists from IIT Kharagpur and other collaborating institutes created a digital soil map for India.
About the Digital Soil Map
- Properties: The digital map will provide information about the properties of soil such as pH, texture, and the amount of organic carbon in the soil.
- Information collaboration: The digital soil maps combine field and laboratory data with geographical and environmental information.
- It also uses mathematical modeling tools to infer soil properties for a location.
- New data generation: This map will also enable scientists to predict soil properties for those regions too for which field data is not available.
- This can be easily updated as the new soil data becomes available.
- Study: The map is created at a resolution of 500m.
- Soil properties were assessed for several layers up to a depth of two meters.
- The texture of the soil was assessed by measuring the sand and soil content.
- The acidity of the soil by measuring the pH
- The organic carbon content of the soil is also ascertained
- Significance: digital soil maps have been used widely across the globe to understand
- the nature of the soil
- arrest its degradation
- in making informed decisions about crop suitability
- In Europe, LUCAS Soil (Land Use/Cover Area frame statistical Survey Soil) is a format for surveying the topsoil from approximately 45,000 locations across the European Union.
- In the U.S. and some other countries there exists a long history of making digital soil maps.
- World Soil Information Service (WoSIS) project at the global level has a WoSIS database that already has 199 soil profile submissions from India.
