Abstract Root‐induced changes in the rhizosphere may affect mineral nutrition of plants various ways. Examples for this are pH response to source nitrogen (NH 4 ‐N versus NO 3 ‐N), and iron phosphorus deficiency. These can readily be demonstrated by infiltration soil with agar containing a indicator. The as much 2 units higher or lower than bulk soil. Also along roots distinct differences exist. In deficiency most plant species their apical root zones increase rate H + net excretion...

Life course researchers have increasingly explored optimal matching analysis (OMA) as a tool for the of sequences, such sections people's status biographies. OMA is usually employed in combination with cluster (CA) to create classifications sequences. In this article, we introduce an analytic strategy that allows assessing classification's internal validity. Using ideal typical sequence representations, test different algorithms and are able optimise fit data. An application analyses...
