RRP Rhizon Irrigators are the perfect match to Rhizoboxes / RhizonBoxes by allowing reseachers to apply water, nutrients or contaminants (e.g. saline solutions, etc.) where and when it matters! Placing Irrigators at different depths allows you to either achieve the most uniform water supply throughout your rootbox, or to more realistically mimic droughts and the inherent loss of soil moisture from top to bottom, e.g. by gradually shifting the water supply to Rhizon Irrigators placed deeper in your rhizoboxes. In addition to irrigation, experiments can be conducted with fertilizers or polluted solutions to simulate the accumulation of excess salt concentrations that often occur with suboptimal irrigation.
Passive irrigation can be achieved by placing storage containers (of water or other solutions) at the same height as the boxes. By changing the height difference between the storage container and the experimental rhizobox, you can influence the suction. For example, if the male luer of the RhizonIrrigator is connected to a water container and the water level is below the level of the RhizonIrrigator in the pot/rhizobox, this means that suction is present - allowing a variety of soil water conditions to be implemented. Since soil characteristics and plant water uptake vary widely, a pre-test is recommended to determine specific soil moisture levels. Get in contact and/or select RhizonIrrigators as accessories in the Rhizobox Config Form.
Rhizon Irrigators have a porous part (10 or 15 cm) with a diameter of 2.5 mm. At one end of the porous part there is a 100 cm tube with male luer lock and at the other end is a 60 cm tube with a female luer lock and stopcock. The porous section is reinforced with nylon wire.
Because of the luer locks, RhizonIrrigators cannot be installed using the normal 4.5 mm side holes in Rhizonboxes but are installed from the top during soil filling. Alternatively, larger holes could be forseen in side panels (on special request).
Store in a dry, normally ventilated place away from sources of heat, ignition and direct sunlight. Store between 0 and 50°C - the membrane modules should not be exposed to freezing. All Rhizon-Irrigators are sold in sets of 10. Continue reading on the properties of the micro-membrane.
