Abstract: Abstract\ud Aims Rhizodeposits collected from hydroponic solutions with roots of maize and barley, and seed mucilage washed from chia, were added to soil to measure their impact on water retention and hysteresis in a sandy loam soil at a range of concentrations. We test the hypothesis that the effect of plant exudates and mucilages on hydraulic properties of soils depend on their physicochemical characteristics and origin.\ud Methods Surface tension and viscosity of the exudate solutions were measured using the Du Noüy ring method and a cone-p...
