Rhizon - Model RPP - Soil Water Sampler
From Rhizon Soil Water Sampler
RPP-Rhizon samplers are used for (un-)disturbed soils (see types below), and are thus ideal to be positioned in Rhizoboxes and RhizonBoxes. Especially RhizonBoxes can be equipped with special openings on the side wall (e.g. at different depth) to insert special Rhizon samplers (with sleeve to prevent leakage of water from the RhizonBox) before or after soil filling. They can be used to collect water from larger zones (length of porous parts: 5 cm or 10 cm) for analyzing macro and micro elements, dissolved organic carbon (DOC) and dissolved gases. Using Rhizons with a 10 cm porous part, maximum yield of water is approximately 4 ml per minute.
