Universal indicator is also available in the market as a ready product. Hence, production of such liquid was tried with available indicators suitable for specific ranges. The combinations were tried. The result is the DHUN indicator. The production of equipment was tried with available electrical devices with standard EC solutions suitable for specific ranges. The combinations were tried. The result is the SLIM stick. The salinity measurement is through this SLIM stick (Salinity Light Intensity Monitor stick). Ranjan Kumar Basak's soil testing methods were modified and brought into this kit method which clearly indicates the per cent of organic matter in soil very easily and quickly. It gives colour development (Orange yellow, olive green and bluish green for low, medium and high organic matter levels).
