Název v původním jazyce

Dual permeability soil water dynamics, plant growth and water uptake by roots in irrigated potato fields.

Popis výsledku v původním jazyce

Water movement and root uptake in a drip-irrigated potato field were studied by field experiments and numerical simulations, using summary results of an EU project. Measurements of soil suction and weather conditions made it possible to derive improved parameters for the dual permeability model S1D DUAL. A reasonable agreement between the measured and the estimated soil hydraulic properties was obtained. The measured root zone depths were near to those obtained by inverse simulation and to a boundary curve approximation. The measured and simulated pressure heads were comparable with those achieved by the Daisy model. During dry spells, the measured pressure heads were higher than the simulated ones. In general, the former oscillated between the simulated values for matrix and those for the preferential flow domain. Irrigation facilitated deep seepage after rain. Several parallel soil moisture sensors are needed for irrigation control. The sensors cannot detect the time when to stop the
