The main function of roots is absorbing water and nutrients (sap) required for the development of plants and trees and anchoring them to the ground. The increasing water shortage in many countries calls for a better understanding of root structure, r

Root water uptake is one of the essential processes within the soil–plant–atmosphere continuum. We present a method for monitoring soil-water redistributions due to water uptake by roots. Our aim is to image and monitor diurnal soil-water redistr

Data from an infiltration and drainage experiment into and from a sand tank model of 5 by 3 m and 2 m deep were reevaluated. The uniform sand overlaid a 0.2-m-thick gravel layer from which five perforated pipes collected drainage flow. The data inclu
