Modelling of root growth of corn (Zea mays L.) under fiield conditions

Abstract

Quantitative studies of root development as it depends on climate, soil and plant properties are one prerequisite to derive relations that allow for a more general, possibly predictive approach to root growth and, consequently, root nutrient uptake. Since net maize root length, e.g. amount of roots that can be measured or observed in a soil sample, increases until flowering, detailed information is needed until this stage is entered. The process of dispersion of the total amount of roots formed in soil, i.e. root penetration into soil and root proliferation in soil layers, has to be quantified.
