Composition and some characteristics of phosphate in coastal sandy soils
In coastal sandy soils, the proportion of phosphate groups can be graded as: fixed phosphate > iron phosphate > aluminum phosphate > calcium phosphate > soluble phosphate. Applying single supper-phosphate (SSP) and fused magnesium phosphate (FMP) has changed the composition of phosphate groups I the coastal sandy soils. However, FMP proves to be more positive.
