Question

How were the soils classified in ancient India?

Answer 1

Hint: During ancient times the soils were classified based on their health and ability to grow crops.
-It was classified into two parts. One describes healthy soil and other unhealthy soil.
-In the modern-day, one category of soil means a soil which can sustain agricultural growth and another one cannot.

Complete answer:
-Soil can be just characterized as a combination of little stone particles/garbage and natural materials/humus which creates on the earth surface and backs the development of plants.
-In India, the soil had been arranged from the ancient period itself even though it was not as detailed as the advanced groupings.
-In the antiquated period, the characterization depended on just two things; regardless of whether the dirt is fruitful or sterile.

Hence the order was:
1. Urvara - fertile: The soil with a good amount of nitrogen and potash suitable for the growth of crops and plants. Urvara alludes to "fruitful land", as characterized in the subsequent part (Dharan Adi-Varga) of the thirteenth century Raj Nighantu or Rajanighantu (an Ayurvedic reference book). Appropriately, it is defined as the land is supposed to be rich, which can be used to cultivate a wide range of grains and because it can create all the harvests and vegetations, it is called Urvara.
2. Usara - sterile: Saline soils or Usara soils contain a bigger extent of sodium, potassium, and magnesium, and subsequently, they are barren and don't uphold any vegetative development.

Additional Information:
In the sixteenth century A.D., soils were characterized based on their inalienable qualities and outer highlights, for example, surface, shading, the incline of the land, and dampness content in the dirt.
In light of the surface, principle soil types were distinguished as sandy, clayey, silty and topsoil, and so on.

Note: Based on richness, soils were made into two classes, Rivara (ripe) and Guevara or usara (sterile).
-Urvara mrittika (ripe soil) was again partitioned into various types considering harvests, for example, have (grain), tila (sesamum), Vashi (rice), Indiana (mung), and so forth.
-Guevara mrittika (sterile soil) was partitioned into usara (sand ground) and maru (desert). Likewise, the dirt that was flooded by stream and under rainfed were known as nadimatrika and devamatrika, respectively.
