Minerotrophic soils and vegetation receive their water supply mainly from streams or springs. This water has flowed over or through rocks or other minerals, often acquiring dissolved chemicals which raise the nutrient levels and reduce the acidity. If these chemicals include chemical bases such as calcium or magnesium ions, the water is referred to as ''base-rich'' and is neutral or alkaline.
In contrast to minerotrophic environments, ombrotrophic environments get their water mainly from precipitation, and so are very low in nutrients and more acidic.
