The increasing demand for water has raised significant concerns regarding the future of irrigated agriculture in various regions of the country. This escalating demand necessitates a profound understanding of crop water requirements, which is crucial for enhancing water use efficiency in irrigation practices. Traditional irrigation systems often lead to uneven water distribution, resulting in over-irrigation in some areas of a field while leaving other areas inadequately irrigated. Such inefficiencies are particularly problematic in the context of changing environmental conditions and the growing scarcity of water resources. These challenges underscore the urgent need for advanced systems that can manage field irrigation more effectively. This paper aims to address these issues by examining the role of soil moisture sensors in irrigation. Soil moisture sensors represent a critical technology for modernizing irrigation practices, offering precise and real-time data on soil moisture levels. This information is essential for optimizing irrigation schedules, ensuring that crops receive the right amount of water at the right time. By integrating soil moisture sensors into irrigation systems, farmers can significantly improve water use efficiency, reduce wastage, and enhance crop yields. The paper provides a comprehensive review of the necessity of soil moisture sensors in contemporary irrigation practices. It delves into the technology behind these sensors, exploring how they function and the various types available. Additionally, the paper discusses the wide range of applications of soil moisture sensors in agriculture, highlighting their role in different aspects of crop management and irrigation scheduling. These sensors are invaluable for precision agriculture, where they help to monitor soil conditions accurately and facilitate data-driven decision-making.
