Soil moisture is a critical factor in plant growth and agricultural productivity. It is the amount of water held in the soil that plants can access to meet their water needs. Too little soil moisture can lead to plant stress and reduced crop yield, while too much soil moisture can cause root damage, nutrient leaching, and soil erosion. Therefore, monitoring soil moisture content is an essential task for farmers and other stakeholders in the agricultural industry. One way to monitor soil moisture content effectively is through the use of soil sensors. In this article, we will explore the role of soil sensors in monitoring soil moisture content.
