The study looked at how much phosphate in soil can be dissolved in water and how much can be absorbed by the soil. They found that the amount of phosphate that can dissolve in water is closely related to the amount of phosphate available in the soil and how much phosphate the soil can absorb. The researchers discovered a strong connection between the amount of phosphate that can dissolve in water and the ratio of available phosphate to phosphate absorbed by the soil. This relationship can help estimate how much phosphate can be dissolved in water based on the characteristics of the soil.
