The latest systematic methods are used in the agricultural sector for engineering, superiority, and advance ecological sustainability. Voltammetric sensors are imperative in detecting multiple analytes, which is an essential key to agricultural processes in a subtle, instant, and tailored fashion. The current chapter proposes an outline of voltammetric sensors that are greatly applicable in the agricultural investigation, emphasizing their importance in the detection of pesticides, monitoring nutrients in soil, water quality measurement, and analyzing heavy metals in agricultural goods. Owing to their distinct features, voltammetric sensors possibly diminish the environmental adversative effects and help in detecting the remnant pesticide. Also, these sensors are vigorous in checking soil health, measuring nutrients in the soil and cleansing fertilization approaches. Additionally, these sensors ascertain heavy metals in agricultural products, protect consumers, and safeguard food safety. Furthermore, monitoring the water quality, enabling real-time water irrigation tracking, and decreasing the risk of effluence voltammetric sensors are used. Imminent studies on multi-parametric sensing systems, augmenting the performance of sensors, and connecting this innovation with smart farming have a lot of perspectives.
