Which of the following media is micaceous, neutral in reaction, good cation exchange capacity, and source of magnesium and potassium? (RJ ACF Ranger 2021)

✅Explanation: Vermiculite is a hydrous phyllosilicate mineral that expands when heated. It is micaceous (has a layered structure), neutral in pH, has a good cation exchange capacity (ability to hold and release nutrients), and is a natural source of magnesium and potassium. These properties make it an excellent medium for plant growth.
📌 Other Options Explanations:
-Sawdust: Sawdust is acidic and can deplete nitrogen from the soil as it decomposes.
-Perlite: Perlite is a volcanic glass that is lightweight and improves drainage.
-Peat: Peat is acidic and has a high water-holding capacity.
