How does calcium oxide and calcium hydroxide help plants grow?

Calcium oxide (CaO) and calcium hydroxide (Ca(OH)₂) are important for plant growth as they contribute to soil pH regulation and improve soil structure. Calcium helps strengthen plant cell walls and is vital for cell division and growth. Additionally, these compounds can enhance nutrient availability by neutralizing acidic soils, promoting better absorption of essential nutrients like nitrogen and potassium. Overall, calcium plays a crucial role in various physiological processes that support healthy plant development.
