Crystallography and equilibrium solubility for ammonium and potassium orthophosphites and hypophosphites
1992
Frazier, A.W. | Waerstad, K.R.
The composition and solubility properties of eight ammonium and potassium orthophosphites and hypophosphites were determined to evaluate the potential of these classes of materials for increasing the plant nutrient content of liquid fertilizers. Phase relationships for the systems (NH4)2O-P2O3-H2O, K2O-P2O3-H2O, (NH4)2O-P2O-H2O, and K2O-P2O-H2O were determined along with the crystallographic properties (X-ray and optical) of the solid phases. Toxicity and phosphite response was tested in greenhouse experiments for the compounds.
