Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the primary modern extraction?Mining of underground evaporite deposits rich in potassium-bearing minerals
2. What is the key physiological role in plants?Osmotic regulation, enzyme activation, stomatal control, and tissue strength
3. What is potash and why is it special?Potash is a salt made from ancient ashes that gives plants the potassium they need to grow big and strong.
4. How does potash help plants?Potassium from potash helps plants use water, make food from sunlight, and keeps their leaves and stems strong.

Evaporite Deposits: Sedimentary rocks formed from minerals left behind after water evaporates, often rich in salts like potash.
Macronutrient: A chemical element required in large quantities for plant growth, such as potassium, nitrogen, and phosphorus.
Electrolysis: A chemical process using electric current to drive non-spontaneous chemical reactions, used to isolate elements.
Stomatal Regulation: The control of the opening and closing of stomata (pores on plant leaves) to manage gas exchange and water loss.
