Sensor-based irrigation systems show potential to increase greenhouse profitabilitywireless sensor-based irrigation systems can offer significant benefits to greenhouse operators.
Advances in sensor technology and increased understanding of plant physiology have made it possible for greenhouse growers to use water content sensors to accurately determine irrigation timing and application rates in soilless substrates.
The wireless sensor systems provide more accurate measurements of substrate moisture than qualitative methods and can save irrigation water labor energy and fertilizer.
