d.
all of the above.

d.

All of the above.

Explanation:

If soil is not protected it will erode.

Traditional methods cause a quick erosion,

Alternative management of soil means different practices , better practices where there is little marging for decomposition of organic matter and preventing soil from wind and water erosion as possible

Soil develops as plants and rocks break down.

Soil comes from the organic matter and minerals as core nutrients.

As the plants, and animals go through decomposition, they lay the foundations for a rich soil which is high on organic components.

Decaying matter is the result of the action of microscopic organisms breakingi down the dead bodies and turning them into organic nutrients

If soil is not protected it will become exhausted.

In order to avoid this, crops need to be harvested and then a period of recovery of the soil is needed in order to continue growing.

If there are no pauses , and no mantaining of the soil is allowed, eventually the soil is exhausted and serves no longer.
