Quantified hypotheses on the relation between root density, mobility of the nutrient concerned and possibilities for actual uptake have to be developed and tested as building stones of 'soil fertility theory'. Depending on the mobility of the nutrient concerned and the buffering capacity of the soil-root system, emphasis should be placed on a comparison of nutrient supply and demand in time ('synchronization') or in space ('synlocalization'). A model approach is outlined.
