Buffering action in plants
http://ecoursesonline.iasri.res.in/mod/page/view.php?id=1534 WebThere are some plants that require strongly acid soils, but all plants of agricultural value fail to grow and die in strongly alkaline soils. The preference of plants for soil pH seems to be linked with the type of buffering system present in the cell sap. Buffering the Soil Reaction: Buffer Action: Buffering refers to resistance to a change in pH.
