1. Presentation on Mini Lab “Mridaparikshak”
Developed by
ICAR-Indian Institute of Soil Science, Bhopal
Under NRM Division of ICAR

2. Why “Mridaparikshak”?
More than 14 crore soil health cards (SHCs) to be prepared and sent to farmers.
Existing Soil Test Kits (STKs) are subject to human error.
Quantitative estimation of micronutrients is also missing.
Hence, this Mini Lab was specifically designed to generate SHC.

15. Summary . . . Mridaparikshak is a minilab, easy to operate.
It can be operated by young educated farmers/rural youth (12th Pass).
Mridaparikshak employs state-of-the-art technology, the results are stable, and reproducible.
Mridaparikshak comes with accessories that can be supplied on demand. These accessories are Geopositioning system and Soil sampling system, Tablet, and Printer.

21. Why “Mridaparikshak”?
1200 STL can analyze only 1.2 crore samples in one year equal to 3.6 crore in three years.
This is only 25% of the total soil health card need to be generated in three years.
Creation of new infrastructure would require 3600 new STLs, would amount to Rs crore.
Existing STKs are qualitative in nature, subject to human error, and can not generate SHC.
Also, the quantitative estimation of micronutrients is missing.
Hence, there was a need to work out Mini Lab specifically designed to generate SHC.
