Question

The proportion of humus is negligible in ___________ soil.​

Answer 1

Answer:

Since humus comprises 60–80% of the total soil organic matter and has a relatively high nitrogen content, it constitutes a large reservoir of nitrogen in most ecosystems.

Answer 2

Answer:

Laterite soil

Explanation:

The Laterite soil develops in the areas with high temperature and heavy rainfall. This soil is highly leached due to heavy rains. The humus content of laterite soil is low as most of the microorganisms, particularly the decomposers, like bacteria, get destroyed due to high temperature.
