<P> To allow plants full realization of their phytonutrient potential, active mineralization of the soil is sometimes undertaken . This can involve adding crushed rock or chemical soil supplements . In either case the purpose is to combat mineral depletion . A broad range of minerals can be used, including common substances such as phosphorus and more exotic substances such as zinc and selenium . Extensive research examines the phase transitions of minerals in soil with aqueous contact . </P> <P> Flooding can bring significant sediments to an alluvial plain . While this effect may not be desirable if floods endanger life or if the sediment originates from productive land, this process of addition to a floodplain is a natural process that can rejuvenate soil chemistry through mineralization . </P>
