Exudates' analysis would help to find minerals and in the form that they are mobilised in the plant because exudates are often plant sap which contains xylem sap as well as phloem sap. It has a composition of amino acids, sucrose, organic and inorganic acids, water, ions, sugars etc. If we perform an analysis of the plant exudates, then we can find out which mineral nutrient is transported in the plant and in which form it is transported.

For eg: Nitrogen can be carried in organic forms like amino acids or as inorganic ions.
