abstract
The role of chosen soil structure parameters in models of crop growth and yield prediction has been analysed on the base of the review of the latest literature. It was stated that the most frequently appearing soil parameters in the chosen models are soil water retention, rooting system, unsaturated and saturated hydraulic conductivity, bulk density or porosity. Comparison of submodels of physical processes in soil-plant-atmosphere continuum in chosen yield production models (CTSPAC, WOFOST, EPIC, CERES-maize) has been presented.
