What is soil map India?
Using data collected over the last three decades, a team of scientists from IIT Kharagpur and other collaborating institutes has created the first digital soil map for India. The digitally accessible resource provides information about properties like soil’s pH, texture, and the amount of organic carbon in the soil.

How are soil maps created?
The process of making an inference about a landscape segment (e.g., a soil map unit) from a few point-based observations using the operative soil-forming factors is “modeling.” Whether the soil map is produced using nothing but a bucket auger and an aerial photo or using geospatial software, the process is a modeling …

Which type of soil is found in India?
India Soil Map. Laterite Soil: The term is derived from the word ‘Later’ which means ‘brick’. Llaterite soil is found in those regions of the country which receive heavy rainfall with alternate dry and wet period – particularly, near the coasts. This kind of soil becomes soft when wet and hardens when dry.
What is soil map?
Soil map is a geographical representation showing diversity of soil types and/or soil properties ( soil pH, textures, organic matter, depths of horizons etc.) in the area of interest. It is typically the end result of a soil survey inventory, i.e. soil survey.
