Why in news
Engineers developed wearable leaf sensors and stem bands that use plant sweat to detect drought, disease, and nutrient stress in real-time before visible symptoms appear.
Background
The technology utilizes tattoo-like leaf sensors and stretchable stem bands powered by plant sweat. It distinguishes between specific stressors including water shortages, salinity stress, and disease to provide early intervention data.
Facts for Prelims
- S&TPlant wearables: Sensors powered by plant sweat to monitor physiological distress.
- FactEarly detection: Sensors identify stress signals days before visible physical symptoms appear.
- S&TStressors monitored: Water shortage, salinity stress, and disease.
For Mains
Q. How can the integration of wearable sensor technology in precision agriculture mitigate crop losses and enhance resource efficiency in Indian farming?
Dimensions to cover in your answer
- Data-driven intervention: Reducing input waste by identifying specific nutrient deficiencies or water stress at the individual plant level.
- Early warning systems: Shifting from reactive to proactive pest and disease management to minimize chemical usage.
- Technological accessibility: Balancing high-tech sensor deployment costs with the economic realities of smallholder and marginal farmers.
