Responses of Reclamation Plants to High Root Zone pH: Effects of Phosphorus and Calcium Availability.

Abstract

Low phosphorus (P) availability and high pH inhibit plant growth in calcareous soils and some oil sands reclamation sites in northeastern Alberta, Canada. In this study, we used a split-root hydroponic setup to test the effects of supplemental P with different calcium (Ca) concentrations and root-zone pH conditions on the growth and physiological response… (More)
