What is the primary function of a soil moisture sensor in agriculture?

The primary function of a soil moisture sensor in agriculture is to monitor soil moisture levels. These sensors provide real-time data on the amount of water contained in the soil, which is crucial for making informed irrigation decisions and managing water resources effectively. By knowing the moisture levels, farmers can optimize irrigation schedules, ensure that crops receive the appropriate amount of water, and avoid over- or under-watering. This not only helps in maintaining healthy crop growth but also conserves water and reduces costs associated with excessive irrigation.

Measuring crop growth potential and evaluating soil nutrient content are related to crop health and fertility management but do not directly involve moisture levels. Predicting pest invasions involves monitoring for signs of pest activity and environmental factors, which is entirely different from the functionality of a soil moisture sensor. The focus of these devices is specifically on the water content in the soil, which is fundamental for efficient crop production.
