Methods to Monitor Soil Moisture - Extension
fyi.extension.wisc.eduIrrigation has become an increasingly important risk management tool for growers. An understanding of soil moisture management is key for growers to make irrigation management decisions. The recommended approach for optimal root zone soil water management includes irrigation water management (scheduling) and soil moisture monitoring.
