Digital Soil Testing Kit (STFR Meter)

Digital Soil Testing kit

The STFR Meter is Unique. The farmer can determine the available nutrients in the soil on the spot himself and unlike other soil test kits, the STFR Meter suggests the correct dosage of the fertilizer based on the crop, Sulphur and micronutrients recommendations based on critical value in soil using the in-built program.

Nutrient deficiency is the major problem in India and farmers often apply fertilizers without any scientific recommendation. This increases the cost of production, lowers farm profits and leads to soil health deterioration.

With vast experience in manufacturing kits and instruments, we have started manufacturing STFR (Soil Test Fertilizer Recommendation) Meter, Digital Soil Testing Kit developed by Indian Agriculture Research Institute, Delhi.

Reliability, portability, and excellent quality are the best of the attributes that are setting our Digital Soil Testing Kit apart. It is convenient to carry and is equivalent to a small laboratory. lt is suitable for agricultural service departments, agricultural dealers and fertilizer manufacturers to test soil and to identify the major & secondary nutrients and up to 100 tests. we are capable of meeting mass requirements and offering products at economical prices.

The heart of our Portable Digital Lab is the STFR Meter, which has been developed by Indian Agricultural Research Institute (IARI), Pusa, New Delhi. The STFR Meter assists the farmer in determining the available nutrients in soil and suggests crop specific fertiliser dosage.
