Question

How do biogeochemical cycles maintain soil fertility?​

Answer 1

Answer:

Soil fertility can be further improved by incorporating cover crops that add organic matter to the soil, which leads to improved soil structure and promotes a healthy, fertile soil; by using green manure or growing legumes to fix nitrogen from the air through the process of biological nitrogen fixation; by micro-dose.

In effect, human activity, sometimes agriculture itself, has disrupted the basic biogeochemical cycling that maintains soil fertility. To the extent that nitrogen or phosphorus is lost from the A horizon, the fundamental movement of nutrients shifts from cycling to net export.
