What has to be done to caliche before plants can be installed?

• A. Removed completely
• B. Desalted completely
• C. Amended Completely
• D. Aerated Completely

Answer: (A)

Caliche is a hard layer of calcium carbonate that forms a dense barrier in soil. It blocks root growth and restricts water movement, so plants can’t establish properly unless this layer is removed. Because the problem is physical, not just chemical, simply desalting, amending, or aerating won’t create the usable rooting space plants need. Removing caliche completely gives you a workable soil profile with adequate drainage and root penetration, which is essential before installation.
