Researchers develop a stable low-cost microsensor from #graphene #oxide to measure #soil moisture on field
#Agriculture uses 80% of the usable water in #India. However, almost half of it is wasted due to inefficient irrigation systems—a scenario to be avoided as water is getting scarce. #Plants get nutrition from the nutrients dissolved in the soil moisture, and they grow best in soil that has optimal moisture. #Farmers need to examine the ground at regular intervals to check the moisture level—a task that could be very tedious in large #farms.
Researchers from the Indian Institute of Technology Bombay (IIT Bombay) seem to have a technological solution to this problem. Led by Prof Maryam Shojaei Baghini, researchers from #IIT #Bombay and #Gauhati University, have designed a robust, accurate and affordable soil moisture sensor using graphene oxide. The sensor detects small changes in soil moisture and is not affected by changes in the temperature and salt content of the soil. It is also stable, giving consistent measurement over a long time. When mass produced, these sensors could cost about ₹2000, which is 40 to 50 times cheaper than other sensors available in the market. These features make the sensor lucrative for use, especially in large farms.
