Development of Advanced Portable Optical Sensor to Monitor Plant Stress Boosts Smart Agricultural Market

Posted On January 18, 2021     

Precision agriculture is an essential method so that the increasing problem of food security can be curbed with the help of sustainable farming. Sustainable farming refers to producing food so that the consumption and textile needs of today's society are met without compromising the future generations' ability to meet their needs. To achieve this, smart technologies are needed for quick diagnosis of plant stresses before the symptoms or yield losses have even occurred. Smart Agriculture Farming refers to using advanced information, big data, the internet of things (IoT), cloud computing, etc., for tracking, monitoring, automating, and analyzing operations in the commercial problem.

To solve the problem of food insecurity, researchers have recently introduced a new Smart Farming Technology. A portable Raman leaf-clip sensor will turn out to be an essential tool in precision agriculture as it allows the diagnosis of nitrogen deficiency in plants. This deficiency can cause premature leaf deterioration and loss of yield. Hence, this new technology may turn out to be an important development in Smart Agriculture Market.

It is designed as a portable optical sensor and can monitor whether a plant is under stress or not. This device provides plant scientists and farmers a new tool that would help in early diagnosis and real-time monitoring of a plant's health in the field.

The researchers' team did in-depth research to develop this technology. The team designed, constructed, tested the sensor, and probed the leaf chemistry to establish its stress rate. They stated Vivo measurements that use potable leaf-clip Raman sensor under full-light growth conditions were steady as per their findings. These measurements were taken with a benchtop Raman spectrometer on leaf-sections under a laboratory setting.

 Nitrogen is a critical nutrient for the plants and is also an essential component of fertilizers. The research demonstrated that early diagnosis of nutrient deficiency in living plants is possible with the leaf-clip sensor.

The study mostly looked at measuring levels of nitrogen in plants. This device can be used to detect levels of other plant stress phenotypes such as saline stress, heat, light stress, drought, and cold stress. A leaf-clip Raman survey can detect most plant stressors. The sensors' are simple in use, and their speed makes them perfect for use in the field to ensure crop health.

Researchers have stated that these sensors may be able to contribute in improving crop yield all over the world and provide more excellent plant resiliency and mitigation of pollution through reduced fertilizer use.
