Evaluation of root development with respect to soil parameter.

Growth and spatial distribution of plant roots, as well as their function as an absorbing surface are influenced by various soil - environment factors. Restricted root growth diminishes their uptake ability and may cause plants stress and diseases and, therefore, to pure yield. As a result, limited nutrient uptake by roots induce high nutrient (e.g. nitrate) concentration in deeper soil layers and can pollute the ground-water. In regard to this, relationships between the soil characteristic and the root growth res. their uptake potential should be taken into consideration. Knowledge of temporal and spatial structure of the root growth, fundamental soil properties and soil nutrient turnover are essential to design programs for the management and protection of agricultural soils.
