Humus Overview

Hi 5th years. Please revise this overview on Humus for tomorrows class. A good idea is to convert into a mindmap.

-is the product of the breakdown of organic matter (dead plants and animals)

-holds minerals in the soil due to its high cation exchange capacity

-absorbs the water and can greatly improve the quality of otherwise poor (sandy) soils.

-improves and strengthens the crumb structure of heavy soils.

-it forms clay - humus complexes, which improves soil stability.

-its dark colour improves the warming capabilities of the soil (i.e. it is able to absorb more heat from the sun)

-can make the soil more acidic (an advantage and disadvantage depending on the use of the soil).
