Abstract
It is generally agreed upon that activity and not concentration governs the physicochemical reactions of ions in solution. It is much less agreed upon that ionic activity governs biological processes, and the problem is open and controversial. Of special interest and importance in connection to soil—plant relationships is the question if, and how, ionic uptake to plants is affected by activity (Dainty, 1962; Shone, 1970) and whether activity may replace concentration in our evaluations of soil solution composition and its effects on plant uptake.
