Abstract
⺠We used planar optodes for simultaneous analysis of rhizosphere pH and O2 dynamics. ⺠Pronounced diurnal changes of O2 concentration and pH along the roots were measured. ⺠Records of 8 weeks revealed a dynamic range of 0-200 μmol O2 Lâ1 and ±1.4 pH units. ⺠Organic acid content decreased up to 58% within 4 mm from the bulk soil to the root.
