Why are Silver Oak trees and Cardamom trees planted in coffee plantations along with the coffee plants?
Show Hint
Solution and Explanation
Silver Oak trees are planted in coffee plantations to provide shade for the coffee plants. Coffee plants thrive in shaded conditions, especially in regions with direct sunlight. Silver Oak trees help in maintaining an optimal microclimate for coffee cultivation by blocking the harsh sun rays and providing protection from wind.
Step 2: Role of Cardamom Plants.
Cardamom trees are often planted in coffee plantations because they grow well under similar climatic conditions as coffee. Additionally, they help in improving the biodiversity of the plantation, preventing soil erosion, and enriching the soil with organic matter, all of which benefit coffee growth.
