Question

1. which is not true of laterite soils? they are red in color. they are very productive agriculturally. they form in the wet tropics. they are enriched in iron oxide.

Explanation:

To determine the false statement about laterite soils, we analyze each option:

• Laterite soils are red due to iron oxide content, so "They are red in color" is true.
• Laterite soils are generally not very productive agriculturally because they are acidic, low in nutrients, and have poor water - holding capacity.
• Laterite soils form in wet tropical regions with high temperature and heavy rainfall, so "They form in the wet tropics" is true.
• Laterite soils are enriched in iron oxide (which gives them the red color), so "They are enriched in iron oxide" is true.

Answer:

The option "They are very productive agriculturally" (the third option from the left, with the text "They are very productive agriculturally") is the false statement.
