Measuring water potential in soils and plants.ARIMAD helps you schedule irrigation wisely! While most monitoring systems only monitor one of these influences, the ARIMAD Pressure Chamber takes all four into consideration when taking a direct plant based measurement.
Pressure Chamber is an excellent choice for routine water measurements for crop plants and light research in plants with little to moderate water stress. Pressure Chamber becomes a standard method for plant-based irrigation decisions in the orchard. The pressure Chamber allows you to monitor the stress level in the tree.It allows you to monitor the plants / fruits and know how much more needs to be watered or lowered.Plant water stress is a sum of four environmental influences; soil moisture, humidity, wind and direct sunlight or heat load.Pressure chamber method demonstrating the plant’s reaction to moisture excess or deficiency. Enables adjustments of irrigation schedule.It is important to bring the measuring instrument to the field to immediately measure the plants. This will prevent errors in the data.

Measuring water potential with a pressure chamber. A cut branch (or leaf or compound leaf) is placed inside the chamber, with the cut end protruding from the seal. Once the chamber has been sealed (hermetically closed), pressure is gradually applied from the gas cylinder.Whenthe pressure in the chamber equals the xylem pressure, a drop of water appears at the cut surface. Assuming that the xylem osmotic potential is very low, the balance pressure represents the equilibrium water potential of the plant material in the chamber.

What is it good for?
The pressure chamber can be used in various fields of agriculture
The pressure chamber method introduced by ARIMAD is widely used in the wine industry within the past decades. Understanding the significance of the quality of grapes for producing premium wine, agronomistsnowadays seek for ways to improve the quality of their grapes. Among woody plants, grapevines are often described as highly vulnerable towater-stress. Vine's physiological characteristics are highly influenced by the irrigation regime applied towards them; for example, deficitirrigation, which means deliberately withholding irrigation to cause stress, is known to improve the grapes quality. But how can wedistinguish between well-irrigated and water stressed vines on the spot. The TheARIMAD pressure chamber allows you to control and monitor the vine'swater statussothat you can stress the vine just to the appropriate level.
