Monitoring soil moisture levels is needed for effective irrigation water management. Irrigation water management requires timely application of the right amount of water. Competition for water, high pumping costs, and concerns for the environment are making good water management more important.

When you measure soil moisture, it identifies if there is a water deficiency that can reduce yields or if there is extreme water application that can cause water logging or leaching of nitrates below the root zone. Measuring soil moisture can also create an awareness and knowledge of every irrigated field that is very useful for planning and management.
