Pressure Chamber technology helps wine growers improve grape quality by supporting more informed irrigation decisions. It is especially useful for regulated deficit irrigation, where controlled vine stress can encourage favorable outcomes. Because it measures plant water stress directly, it reflects the combined effects of soil moisture, humidity, wind, and heat load.
Pressure Chamber technology has become a standard tool for plant-based irrigation decisions in orchards as water resources become more limited. In almond production, it can help determine when to begin irrigation and support better water management through key stages of the season. It is especially valuable near hull split and harvest, when careful stress management can help reduce problems and support a successful harvest.
Pressure Chamber technology has become a standard tool for plant-based irrigation decisions in walnut orchards as water resources become more limited. It helps growers determine when to begin irrigation and maintain better water balance for growth without over-irrigating. Near harvest, it also supports stress monitoring when irrigation is often reduced to keep the orchard floor dry.
Pressure Chamber technology gives prune growers a practical way to make more informed irrigation decisions throughout the season. It can help identify when irrigation should begin, support steady orchard moisture for growth, and reduce the risk of excess water that may contribute to disease or harvest issues. As harvest approaches, it also helps monitor plant stress when irrigation is scaled back to maintain field conditions.
