Physicochemical Features of Polyphosphate Transformation in Model Soil Solutions
The transformations of low- and high-molecular-weight polyphosphates (compound fertilizers) were studied in model soil solutions. It was shown that low-molecular-weight polyphosphates (because of their complexing ability) and high-molecular-weight polyphosphates (polymetaphosphate) (because of their ion-exchange and complexing abilities) significantly differed from orthophosphate, especially water-soluble ones.
