To overcome dry spells, plant roots can use macroscopic structures in the soil to reach deeper water reservoirs. We used R-SWMS, an explicit soil- and root water uptake model and integrated different kinds of macropores within the soil domain. Root growth is based on vector addition and influenced by the local soil parameters, e.g. penetrometer resistance or nutrient availability, around a growing root tip. Root water uptake from the macroporebulk soil interface was simulated with respect to the contact area between roots and bulk soil. The macropore was assumed to be air-filled.
