Thermodynamics Of Phosphate Absorption On Several Charcoals, James Duncan Beaton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Phosphorus has long been recognized by agriculturists as being one of the elements essential for plant growth. Although the total phosphorus content of a soil may be high, the amount of phosphate actually available for plant growth is often low. Many agencies such as inherent low solubilities of phosphate compounds, adsorption on Ca C03, adsorption in the diffuse double layer of clay micelles, and chemical precipitation of phosphate which refers to the removal of phosphate ions from solution and their chemical bonding to the solid phase have been studied to explain the lack of phosphate availability.
