Question

how does soil erosion affect the nitrogen cycle

Answer 1

Erosion affects production of new photosynthate and consequently input of C into soil due to its effect on soilfertility. The redistribution of topsoil and associated nutrients due to soil erosion changes the spatial distribution and rates of plant productivity in eroding watersheds.

Answer 2

The redistribution of topsoil and associated nutrients due to soil erosion changes the spatial distribution and rates of plant productivity in eroding watersheds. ... Erosion can also affect the physical and chemical mechanisms that stabilize C and N, and slow down their losses from the soil system.
