Integrating precision technology in mechanized fertilizer sprayers: A step towards sustainable agriculture

Abstract

India, with over 70% of its population directly or indirectly dependent on agriculture, continues to face significant challenges stemming from low productivity, traditional farming practices, and limited mechanization—particularly among small and marginal farmers. This research presents a novel approach to integrating precision technology into mechanized fertilizer sprayers to enhance operational efficiency, reduce labor demands, and minimize input wastage. The developed system incorporates an ergonomic, gear-driven manual propulsion mechanism coupled with a precision-controlled multi-nozzle boom for uniform chemical distribution. The design emphasizes affordability and adaptability for small landholdings, with the potential for future integration of GPS, Variable Rate Technology (VRT), and sensor-based automation. Traditional methods such as backpack sprayers are labor-intensive, inefficient, and often result in uneven fertilizer and pesticide application—leading to poor crop performance and environmental risks. The proposed solution eliminates the need for manual pumping or fuel-powered operation, thus lowering operator fatigue and operational costs. The inclusion of adjustable nozzles and height-control mechanisms ensures uniform spraying, reduced chemical usage, and adaptability across diverse field conditions. This innovation bridges the gap between mechanical functionality and precision control, promoting sustainable agricultural practices and empowering grassroots farmers with accessible modern technology. It marks a significant advancement in precision agriculture, contributing to higher productivity, environmental sustainability, and economic viability.
